Whether you are a digital nomad hopping between co-working spaces in Bangkok, a family on holiday exploring the Scottish Highlands, or a business professional requiring constant, secure access to corporate resources, mastering your router is the key to stress-free, uninterrupted connectivity. This comprehensive walkthrough will cover every critical aspect, ensuring that your 4G LTE Mobile WiFi Routers serve you faithfully, providing the robust, high-speed connection you need to make your travels both productive and enjoyable.

Initial Setup: Getting Started

Unboxing and Charging

The journey to mastering your portable network begins the moment you open the box. While the contents may vary slightly by manufacturer, almost every package for 4G LTE Mobile WiFi Routers will include the router itself, a USB charging cable (often USB-A to Micro-USB or USB-C), and a wall adapter. Before you even think about inserting a SIM card, it is absolutely critical to charge the internal battery fully. Most modern routers ship with a partial charge, which is sufficient for a brief test but not for real-world use. Connect the device to a power source using the provided cable and adapter. Look for a small LED indicator on the device; it will typically turn red or orange while charging and change to green or blue when the battery is full. A full charge cycle usually takes between 2.5 and 4 hours, depending on the battery capacity (which is often in the 2000mAh to 5000mAh range). Resist the temptation to power on the device during this initial charge, as modern lithium-ion batteries benefit from a complete, uninterrupted first charge to calibrate their power management systems. This initial patience will pay dividends in long-term battery health and consistent performance. While charging, take a moment to inspect the device. Locate the SIM card slot, which is often hidden under a small rubber flap or a sliding panel on the side or back. Also, note the WPS button (if present) and the reset pin-hole, which you should only use if you need to restore factory defaults. Understanding these physical attributes before proceeding will make the next steps seamless.

Inserting Your SIM Card (Physical vs. eSIM)

With the battery fully charged, the next critical step is providing your router with its internet lifeline: the SIM card. This is where a key decision comes into play, especially relevant for users in dynamic markets like Hong Kong, which serves as a hub for travelers. For standard physical SIMs, power off the router completely—do not just put it to sleep. Using your fingernail or the provided tool (if any), gently open the SIM card tray. Your device will require a specific size: usually a Nano-SIM or Micro-SIM. Insert the card following the orientation indicated by a small diagram near the slot, ensuring the gold contacts face down. A satisfying click confirms it is seated correctly. Alternatively, a growing number of modern 4G LTE Mobile WiFi Routers, particularly those from brands like Huawei, Netgear, and GlocalMe, now support eSIM technology. An eSIM is a programmable SIM embedded directly into the router's hardware. Instead of inserting a physical card, you scan a QR code or download a profile from a provider. This is exceptionally convenient for international travel because you can instantly purchase and activate a local data plan from Hong Kong's leading carriers like 3 Hong Kong, CSL, or SmarTone without needing to find a store. Hong Kong, with its 11 million mobile subscriptions for a population of 7.5 million, has a highly competitive market; many providers offer excellent prepaid travel SIMs at very low prices, such as HK$198 for a 30-day plan with 50GB of data. Whether you choose physical or eSIM, ensure that the plan you purchase includes data (not just voice/SMS) and that it operates on the FDD-LTE bands supported by your router. Most global routers support bands 1, 3, 7, 8, and 20 (for Europe/Asia) and bands 2, 4, 5, and 12 (for the Americas). Double-checking your specific router's frequency compatibility with your destination's bands is a mark of an expert traveler.

Powering On and Initial Configuration

Once the SIM card is secure, power on the device by holding the power button for 2-3 seconds. The LED indicators will cycle through a startup sequence. Look for the Wi-Fi signal and the globe/internet indicators; a solid blue or green globe usually means you have a successful connection to the cellular network. Your router will now broadcast its default Wi-Fi network. The default SSID (network name) and password are almost always printed on a sticker attached to the bottom or side of the router. This is your temporary access key. Do not share this initial connection with anyone. Connect your phone, tablet, or laptop to this network. Open a web browser, and you will likely be redirected to the router's web admin interface—often accessible via an IP address like 192.168.1.1 or 192.168.0.1, which will also be printed on the sticker. If the page does not load automatically, manually type the IP address into your browser's address bar. The default login username and password are also typically provided on this sticker (commonly 'admin'/'admin'). Upon first login, the device may prompt you to choose a language, set the date/time, and select your region. For Hong Kong, ensure you set the time zone to UTC+8. This initial setup wizard is your first opportunity to customize the device. Do not skip it. Within this admin panel, you can view the signal strength, the connected mobile network (e.g., "SmarTone HK LTE"), and the associated IP address. This is also where you might need to manually input the APN (Access Point Name) settings for your carrier if the router does not auto-configure them. For Hong Kong providers, common APNs include smarone (SmarTone), mobile.three.com.hk (3 HK), and csl (CSL). Correct APN configuration is non-negotiable for establishing data connectivity. Confirm that the "Data Connection" state shows as "Connected" before proceeding to connect your devices.

Connecting Your Devices

With the router operational and broadcasting its network, you can now connect your devices. Navigate to the Wi-Fi settings on your laptop or smartphone, find the SSID you saw on the sticker, and enter the corresponding password. For the initial connection, do this for at least two devices (e.g., a phone and a laptop) to confirm that the 4G LTE Mobile WiFi Routers can handle multiple concurrent connections. Most modern travel routers can support between 10 and 32 devices simultaneously, but the actual performance depends on the available LTE bandwidth. Once connected, perform a quick speed test using a service like Speedtest.net. In Hong Kong, which boasts one of the fastest average mobile internet speeds globally (often exceeding 50 Mbps down), you should expect to see speeds of 20-40 Mbps in a suburban area and 50-80 Mbps in a central location like Tsim Sha Tsui or Central. If you see a connection but no internet access, go back to the admin panel and verify your APN settings. If the speeds are abysmally low (under 5 Mbps), check the signal strength indicator on the router. A weak signal may require moving the router closer to a window or to a higher vantage point. This test phase is also the perfect time to familiarize yourself with the router's internal interface. Browse around to see how many devices are currently connected, your current data usage breakdown (most routers track this by device), and the signal strength of your chosen cell tower. Understanding these basic metrics now will empower you to optimize your network later.

Optimizing Performance and Security

Changing Default Passwords and SSIDs

The single most impactful step you can take to secure your portable network is to immediately change the default admin password and the Wi-Fi network name and password. Default credentials are universally known and published online. Leaving them active makes your device a prime target for intruders who could drain your data allowance, monitor your traffic, or even manipulate your router's settings. Access the router's admin panel (refer to the IP address on the sticker) and navigate to the 'System' or 'Administration' section. Change the admin login from the generic 'admin' to a unique username (e.g., 'alice_travels_2024') and a complex, hard-to-guess password that combines uppercase and lowercase letters, numbers, and symbols. Do not use your birthdate or simple patterns like 'abc123'. Next, go to the 'Wi-Fi Settings' section. Change the SSID from something generic like 'Huawei-E5577-ABCD' to something subtle that does not scream "valuable tourist router". A good option might be a neutral name like 'Home_Office_24' or 'Personal_Hotspot_2'. Avoid naming it 'HK-Free-WiFi' or 'Bali-Beach-Net', as this attracts unwanted attention. Set a new Wi-Fi password that is at least 12 characters long. Using WPA3 encryption is best, but if your devices are older, ensure you are using WPA2-AES (not TKIP). This change immediately creates a private, secure environment, significantly reducing the risk of 'piggybacking' or malicious access. In high-traffic environments like Hong Kong International Airport or Disneyland, a well-secured router is your first line of defense against data theft and unwanted bandwidth sharing.

Firmware Updates for Stability and Features

Firmware is the operating system of your 4G LTE Mobile WiFi Routers. Keeping it up to date is just as important as updating your phone or computer's software. Manufacturers like Huawei, TP-Link, and D-Link regularly release firmware updates that address critical security vulnerabilities, improve LTE modem stability, and occasionally introduce new features (e.g., better battery optimization or roaming support). Within the admin panel, look for a section labeled 'System Update', 'Firmware Upgrade', or 'Tools & Settings'. Most routers have an 'Online Update' feature that will automatically check the manufacturer's servers for the latest version. It is crucial to perform this check before you depart on your trip, while you are connected to a reliable home network. If you wait until you are abroad, downloading a large firmware file (often 30-100 MB) can eat into your precious travel data plan. In Hong Kong, where 5G is ubiquitous, many routers from 2023 onward also receive updates that improve how they hand off between 4G and 5G towers, though we are focusing on the robustness of 4G LTE Mobile WiFi Routers. A firmware update can fix known bugs, such as the device randomly rebooting or losing the APN configuration. To ensure a successful update, connect the router to a power outlet via the wall charger (do not use a computer's USB port, as power may be insufficient) and do not power off the device during the process. A failed firmware update can 'brick' the device, rendering it unusable. Therefore, only use official firmware from the manufacturer's support website, and never download 'modded' or 'custom' firmware from unverified sources, as these can introduce major security risks. Making firmware updates a routine part of your device's maintenance will ensure long-term reliability and peak performance.

Band Selection and APN Settings

While 4G LTE Mobile WiFi Routers are designed to automatically connect to the best available network, there are scenarios where manual configuration is needed for optimal performance. One of the most powerful but often overlooked settings is 'Band Locking' or 'Network Selection'. By default, the router scans all available LTE bands (e.g., Band 1 at 2100 MHz, Band 3 at 1800 MHz, Band 7 at 2600 MHz, Band 8 at 900 MHz). While automatic selection usually works fine, it can sometimes cause the router to latch onto a 'faster' but congested band or a band with poor penetration through walls. In a concrete-heavy environment like many hotel rooms in Hong Kong, forcing the router to use a lower-frequency band like Band 8 (900 MHz) can provide dramatically better signal penetration and stability, even if the theoretical top speed is lower. To do this, log into the admin panel and look for 'Band Management', 'LTE Band Selection', or 'Preferred Network'. Some routers allow you to tick or un-tick specific bands. If you are experiencing slow speeds in a crowded area (e.g., a convention center), you might try locking onto a different band. However, be careful—selecting the wrong band can cause a complete loss of signal. Similarly, APN settings are critical. While most routers auto-configure APNs for major carriers like 3 Hong Kong, CSL, or SmarTone, if you use a lesser-known Mobile Virtual Network Operator (MVNO) or a prepaid card from a specific region, you may need to input the APN manually. Incorrect APN settings are the number one cause of 'no internet access' after a successful SIM card detection. Always note down the correct APN provided by your SIM card issuer. In Hong Kong, common APNs are smarone (SmarTone), mobile.three.com.hk (3 HK), and csl (CSL). A single typo here will kill your data session, so double-check. Mastering these manual adjustments separates a novice from a power user.

Using a VPN for Enhanced Security

Security on public networks is a paramount concern for any traveler, and a Virtual Private Network (VPN) is the gold standard for protecting your data. When you connect to the internet via your 4G LTE Mobile WiFi Routers, your traffic is theoretically encrypted over the air to the cell tower. However, once it hits the internet backbone, it can be vulnerable, especially when accessing sensitive accounts like banking or corporate email in a foreign jurisdiction. A VPN creates an encrypted tunnel from your device to a server in a location of your choosing (e.g., a server back home in the UK, USA, or a neutral location). You have two primary options: device-level or router-level VPN. Device-level VPN is the simplest: you install a VPN app (like NordVPN, ExpressVPN, or Surfshark) on your phone or laptop. This only encrypts traffic from that specific device. Router-level VPN is far more powerful. If your travel router supports OpenVPN or WireGuard client capabilities (check the admin panel under 'VPN' or 'Advanced Settings'), you can configure the router itself to connect to your chosen VPN service. This means every single device that connects to the router—your phone, tablet, laptop, e-reader, everything—is automatically protected through the VPN tunnel. This is incredibly convenient, as you do not need to install apps on every device. Furthermore, it can help you 'geo-shift' your location to access content available only in your home country. For example, if you are traveling in Hong Kong and want to watch BBC iPlayer, you would connect your router to a VPN server in the UK. When configuring a router-level VPN, ensure your VPN provider offers a dedicated configuration file or manual setup guide. Be aware that a VPN will reduce your raw speed slightly (by 10-20%) due to the encryption overhead, but the security and privacy benefits far outweigh this minor performance hit, especially in regions with strict internet censorship or surveillance.

Managing Connected Devices and Data Usage

One of the biggest challenges of using 4G LTE Mobile WiFi Routers on the road is managing your data allowance. Unlike your unlimited home fiber connection, travel data plans (especially high-speed ones) are often capped at 20GB, 50GB, or 100GB. Exceeding this cap can result in throttled speeds (e.g., down to 128 kbps) or expensive overage charges. Most travel routers include a built-in data usage monitor. Log into the admin panel and find the 'Statistics', 'Data Usage', or 'Traffic Manager' section. This will show you how much data you have used since the last reset. Make it a habit to reset this counter every time you insert a new SIM card or start a new billing cycle. A pro tip: set a hardware data limit if your router supports it. For instance, if you have a 30GB plan, set the router to cut off the internet at 28GB to leave a safety buffer. Furthermore, you can monitor which connected devices are consuming the most bandwidth. A single device streaming high-definition video (e.g., Netflix, which uses about 3GB per hour) can decimate your monthly allowance in a few hours. Many routers allow you to implement Quality of Service (QoS) rules to limit the bandwidth of specific devices. For example, you could limit your kids' iPad to 5Mbps to prevent them from hogging the connection while you work. Actively managing your data usage prevents the shock of running out of data during a critical video call or while navigating an unfamiliar city. For Hong Kong, where high-speed 5G alternatives exist but where LTE remains the most reliable backbone, monitoring your usage is the difference between a smooth trip and a disconnected one.

Advanced Tips for Travelers

Sourcing Local SIM Cards: Best Practices

The heart of your portable network is the SIM card inside it. While roaming with your home carrier can be convenient, it is often prohibitively expensive. Sourcing a local SIM card is the most cost-effective way to get high-speed data. When arriving in a destination like Hong Kong, you have several options. At Hong Kong International Airport (HKIA), you will find official counters for major carriers like 3 HK, CSL, and SmarTone as soon as you exit customs. These are trustworthy, but often priced at a premium for convenience. A better strategy is to head to a local 7-Eleven or Circle K convenience store, or a dedicated electronics store like Fortress or Broadway. These outlets sell prepaid 'Travel SIM' packages that offer a high volume of data (e.g., 50GB for 30 days) for a very reasonable price, often around HK$150 to HK$250. Before buying, verify that the card supports full-speed 4G LTE data on the bands your router uses. Some 'data-only' SIM cards do not support voice or SMS, which is fine for a router. A critical best practice is to never throw away the SIM card packaging. It contains the mobile number (for registration, if needed) and, most importantly, the APN settings. Pro tip: purchase a SIM card that allows 'tethering' (sharing internet). Some cheap or unlimited plans from certain providers in other countries restrict tethering through TTL (Time to Live) analysis, but in Hong Kong, this is rarely an issue for mainstream prepaid cards. Another insider trick is to buy a SIM card from an MVNO (Mobile Virtual Network Operator) like Hello 喂 (Hello SIM), which uses the 3 HK network and offers excellent value. Always keep the original SIM adapter handy in case you need to switch the card back to a standard phone.

Conserving Battery Life

A dead battery renders even the most advanced 4G LTE Mobile WiFi Routers useless. Battery life is arguably the most critical physical attribute of these devices during travel. A typical router can last 8 to 12 hours on a single charge, but this drops significantly under heavy use. To maximize battery life, first activate the router's 'Power Saving Mode' or 'Automatic Shutdown' feature. This is often found in the 'Battery' or 'Power Management' settings within the admin panel. This mode will automatically reduce the Wi-Fi transmission power (TX power) if it detects that all connected devices are nearby, which saves considerable energy. Secondly, set an 'Idle Timeout'. If no devices are connected to the router for, say, 10 minutes, the router can automatically turn off its Wi-Fi radio or go into deep sleep. When you wake your device and try to reconnect, the router will wake up instantly. Thirdly, turn off the Wi-Fi when you do not need it. If you are in a meeting, having dinner, or sleeping, holding the power button for a few seconds to shut down the router fully is a simple habit that preserves battery charge for when you truly need it. Another significant battery drain is the screen (if your device has one). Set the backlight timeout to the minimum (e.g., 15 seconds). Furthermore, avoid using the router while it is charging via a power bank, especially a low-quality one, as this can generate heat which degrades battery health. For Hong Kong's humid summers, the battery swells more easily when hot. Keep the router out of direct sunlight and away from hot surfaces. By conscientiously managing these power settings, you can easily stretch a single charge from breakfast to late evening, covering a full day of sightseeing and work.

Leveraging Router Features

Most users only scratch the surface of their router's capabilities. Beyond basic Wi-Fi, your 4G LTE Mobile WiFi Routers likely have several hidden features that can significantly enhance your travel experience. The 'Guest Network' feature is a gem for security-conscious travelers. When staying in a hostel, Airbnb, or co-working space, you can enable a guest network that is isolated from your main network. This prevents other users from accessing your shared folders or printer, even if they have the guest password. It's a simple way to share your connection without compromising your private devices. Another powerful feature is the 'Storage Sharing' or 'Media Server' function. Many routers have a USB or microSD card slot. Insert a USB drive with your favorite movies, music, or e-books. You can then access this shared storage from any device on the network—your phone, tablet, or laptop—without needing to rely on cloud services or a separate external hard drive. For long flights or areas with poor internet, this is a lifesaver. Additionally, do not overlook the Ethernet port. While the port is usually configured as a WAN port (to connect to a hotel wired network), many modern routers allow you to switch it to LAN mode via the admin panel. In this LAN mode, you can connect a game console, a smart TV without Wi-Fi, or even a wired printer directly to the router for a faster, more stable connection. During a visit to Hong Kong, if you are staying in a serviced apartment that provides a wired Ethernet connection, you can use your travel router in 'WISP' or 'Ethernet WAN' mode to turn that wired internet into a private Wi-Fi network for all your devices. This feature alone transforms the utility of your router from a mobile hotspot into a full-featured home router replacement.

Understanding Data Roaming vs. Local Data

A fundamental decision every traveler must make is whether to use a roaming plan from their home carrier or to purchase a local SIM card. This choice has profound implications for cost, speed, and latency. Data roaming works by your home carrier making a deal with a local carrier in the visited country (e.g., your UK carrier might partner with CSL in Hong Kong). While it is convenient because you do not need to change SIMs, it comes with significant drawbacks. Roaming data is almost always more expensive—often by a factor of 3 to 10 compared to local data. Additionally, your data is often backhauled to your home country before reaching the internet, increasing latency (ping time). For example, browsing a website from Hong Kong will have to route through London, adding 150-300ms of delay. This makes it feel sluggish and is terrible for real-time applications like video calls or gaming. In contrast, using a local Hong Kong carrier (e.g., 3 Hong Kong or SmarTone) provides direct, local internet access. You get the local IP address, which is better for accessing local services and geo-restricted content. The speeds are the fastest possible because you are directly connected to the carrier's backbone. With 4G LTE Mobile WiFi Routers, the local SIM approach is almost always superior for performance and budget. The only exception is for very short trips (1-2 days) where the hassle of buying a SIM outweighs the cost. However, for any trip longer than 3 days, the financial savings of a local SIM are undeniable. In Hong Kong, a 30-day, 50GB local data plan can cost as little as HK$198, whereas roaming from a European carrier for the same data could easily exceed HK$1000. By understanding these cost and performance dynamics, you can make an informed decision that aligns with your travel style and budget.

Common Troubleshooting Guide

No Internet Connection

This is the most frustrating issue, and it's usually the easiest to fix. When your device connects to the router's Wi-Fi but you get 'No Internet', the problem is almost always with the SIM card or its configuration. First, reboot the 4G LTE Mobile WiFi Routers completely: turn it off, remove the battery (if possible), wait 30 seconds, reinsert it, and power on. This clears the device's memory. If that fails, check the SIM card. Is it inserted correctly? Is it activated? For prepaid cards sold in Hong Kong, activation is sometimes not automatic and requires a simple phone call or SMS to a specific number. Try putting the SIM into a standard phone to ensure it works there first. If it works in the phone but not the router, the issue is likely the APN settings. Go to the router's admin panel and manually input the correct APN for the carrier (e.g., smarone for SmarTone). A single wrong character will block the connection. Another possibility is that your data plan has run out. Log into the carrier's website or app to check your remaining balance. In some cases, the router might be set to the wrong network mode. In the admin panel, under 'Network Settings', ensure it is set to 'LTE/4G Only' or 'Auto' (4G/3G). If you are in a remote area in Hong Kong (like some of the outlying islands), the signal might be very weak. Move the router near a window or to a higher floor. Finally, check if there is a carrier blackout or network outage. Checking local forums (e.g., Hong Kong Wi-Fi discussion groups) can confirm if others are having issues with the same provider.

Slow Speeds

Slow internet is subjective, but if you are getting speeds under 5 Mbps while expecting 20+, there is a bottleneck. The first suspect is network congestion. In a dense urban environment like Hong Kong, central areas like Causeway Bay or Mong Kok experience heavy LTE usage during peak hours (6 PM-9 PM). Try moving to a less crowded area or wait until off-peak hours. Second, check the signal strength indicator on the router. If it shows only 1 or 2 bars out of 5, the signal is weak. Reposition the router: windowsills, high shelves, or even a different corner of the room can make a huge difference. Third, consider 'Band Locking'. As mentioned earlier, forcing the router to a different LTE band (like Band 8 at 900 MHz) can improve stability and effective throughput in weak-signal environments. Fourth, check which devices are connected. A single device streaming 4K video will saturate the connection. Use the admin panel to see the active data usage per device and disconnect any bandwidth hogs. Fifth, investigate the SIM card itself. Some 'unlimited' travel SIMs have a 'Fair Usage Policy' (FUP). After using a certain amount of high-speed data (e.g., the first 10GB), the carrier may throttle the speed to 384 kbps or 1 Mbps for the rest of the month. Check the fine print on your SIM card package. Finally, firmware in your 4G LTE Mobile WiFi Routers may be outdated. A new firmware can optimize the modem's performance, especially for carrier aggregation (combining multiple LTE bands for higher speeds). Performing a firmware update is a reliable long-term fix for speed issues.

Device Not Connecting

When a specific device (e.g., your laptop) cannot connect to the router, but others can, the problem is usually on the device, not the router. First, 'Forget' the Wi-Fi network on that device and reconnect. Go into your device's Wi-Fi settings, find the network name, tap 'Forget', then select the network again and enter the password carefully. A simple typo is a common cause. Second, check for IP conflicts. Most routers use DHCP (Dynamic Host Configuration Protocol) to automatically assign IP addresses. If your device has a manually configured static IP address that conflicts with the router's range (e.g., if the router uses 192.168.1.x, but your device is set to 192.168.2.x), it won't work. Set the device's IP configuration to 'Obtain automatically (DHCP)'. Third, if the problem persists, the router's DHCP pool might be full. Most travel routers can handle 10-32 devices, but if you've connected 40 devices over the past few weeks, the lease table might be full. Reboot the router to clear the table. Fourth, check the router's 'Access Control' list. Some routers have a feature to blacklist certain MAC addresses. Log into the admin panel and check 'MAC Filtering' or 'Device Management' to ensure your laptop's MAC address is not blocked. If you are trying to connect an older device (like a 2015 Kindle or an IoT gadget), it might not support the modern WPA2/WPA3 encryption standard. Consider creating a 'Gast Network' that uses WPA2 or even WPA (less secure, but compatible) as a temporary workaround, but ensure you use a strong password for it.

Battery Draining Quickly

A battery that used to last 10 hours but now barely makes it through 4 is a sign of degradation or a setting issue. First, check the router's power-saving settings as discussed in the battery conservation section. Ensure 'Power Saving Mode' is enabled and the idle timeout is set to 5-10 minutes. Second, evaluate the physical conditions. Lithium-ion batteries degrade significantly faster in high heat. If you have been using the router in direct sunlight, in a hot car, or in a humid environment (like a tropical beach), the battery's chemical composition is damaged. In Hong Kong's summer (30-35°C with high humidity), this is a common issue. Third, connected devices affect battery life. The more devices connected, and the more data they are transferring, the harder the modem and CPU work, draining the battery faster. Disconnect devices you are not using. Fourth, check the firmware for battery management updates. Manufacturers sometimes release updates that optimize power consumption. If the battery is genuinely old (more than 2 years of regular use), it might simply have reached the end of its lifecycle (typically 300-500 charge cycles). In this case, the only solution is to replace the battery. Many travel routers like the Huawei E5577 and Netgear Nighthawk M1 have user-replaceable batteries. Purchase a genuine battery from the manufacturer or a reputable Hong Kong electronics retailer (e.g., Fortress or Broadway). Avoid cheap third-party batteries, as they can be fire hazards or have inflated capacity claims. If the battery is not user-replaceable, your only option is to use the router plugged into a power bank or wall charger permanently, which effectively turns it into a wired modem.
