Understanding Wi-Fi Dead Zones and Their Causes
Why Do Dead Zones Appear?
Wi-Fi dead zones are areas within your home or office where wireless internet signals are either extremely weak or non-existent. These spots can severely hinder your online activities. Several factors contribute to the formation of these frustrating areas:
Physical Obstructions: Building materials like thick concrete walls, brick, stone, and metal can significantly block or absorb Wi-Fi signals. Even large metal appliances or furniture can create interference. Older buildings, often constructed with denser materials, are particularly prone to these issues.
Distance from Router: The further you are from your main router, the weaker the Wi-Fi signal becomes. Signals naturally degrade over distance.
Interference from Other Devices: Household electronics such as microwaves, cordless phones, baby monitors, and security systems can operate on similar frequencies, leading to signal interference and reduced Wi-Fi performance.
Router Placement: An improperly placed router, especially if it's in a corner, hidden behind furniture, or in a closet, can limit its ability to broadcast a strong signal throughout the entire space. Optimizing router location is a crucial first step in improving overall Wi-Fi coverage.
Network Congestion: If many Wi-Fi networks in your vicinity are using the same wireless channels, this can lead to congestion and weaker signals, even causing dead zones.
Identifying dead zones often involves simply walking through your home with a connected device and noting where the signal becomes weak or disconnects. Apps like Wi-Fi Analyzer can provide detailed information on signal strength and channel congestion, helping you pinpoint problem areas more accurately.
Evaluating Your Proposed Solution: TP-Link AC1750 Extender and Ethernet
A Synergistic Approach to Connectivity
Your plan to use a TP-Link AC1750 Wi-Fi range extender in an adjacent room and then run an Ethernet cable to the PC in the dead zone is an excellent combination of wireless extension and wired reliability. Let's break down why this is a viable and effective solution:
The Role of the TP-Link AC1750 Wi-Fi Range Extender
The TP-Link AC1750 is a dual-band Wi-Fi range extender, meaning it operates on both the 2.4GHz and 5GHz bands. It typically offers speeds up to 450Mbps on 2.4GHz and 1300Mbps on 5GHz, for a combined AC1750 rating. Importantly, it features a Gigabit Ethernet port, which is crucial for your setup.
Signal Amplification: The primary function of a Wi-Fi extender is to pick up the existing Wi-Fi signal from your main router and re-broadcast it, effectively extending the coverage area. By placing it in an adjacent room that already receives good Wi-Fi coverage (500Mbps from your VX420-G2V), you ensure the extender itself has a strong signal to work with. This is vital because an extender can only re-broadcast a signal as good as it receives.
Dual-Band Capability: The AC1750's dual-band support allows it to handle more devices and reduce congestion, potentially improving overall performance.
Strategic Placement: Placing the extender "halfway" between your main router and the dead zone (or, in your case, in an adjacent room with good signal) is generally the recommended approach to maximize its effectiveness. This allows it to capture a strong signal and efficiently extend it.

The Power of the Ethernet Connection
The second part of your solution, running an Ethernet cable from the AC1750 extender to your PC, is where this plan truly shines. While the extender boosts Wi-Fi coverage, wireless signals can still be susceptible to interference and degradation over distance, especially when passing through walls.
Bypassing Wireless Weaknesses: By using an Ethernet cable, you create a direct, stable, and high-speed wired connection to your PC. This completely bypasses the weak Wi-Fi signal in the "dead zone" room, ensuring your computer receives optimal internet performance.
Gigabit Speeds: The TP-Link AC1750 extenders (like the RE450 model) typically come equipped with Gigabit Ethernet ports, which support data transmissions up to 1,000 Mbps. This means your PC can achieve speeds significantly faster and more reliable than a wireless connection, even if the wireless signal to the extender is 500Mbps. The wired connection maximizes the effective bandwidth delivered to your device.
Reduced Latency and Interference: Wired connections inherently have lower latency and are not subject to the same wireless interference that can plague Wi-Fi. This is particularly beneficial for activities like online gaming, large file transfers, or video conferencing where stability and speed are paramount.
Setting Up Your TP-Link AC1750 Extender
Setting up a Wi-Fi extender like the TP-Link AC1750 is generally straightforward. Here are common methods:
WPS Button (Wi-Fi Protected Setup): This is often the quickest method. Plug the extender into an outlet near your main router. Once powered on, press the WPS button on your main router, then within two minutes, press the WPS button on the extender. The devices should connect automatically. Once connected, you can move the extender to its optimal location (the adjacent room with good signal).
TP-Link Tether App: Many modern TP-Link extenders can be set up via the Tether app on your smartphone or tablet. Download the app, connect your mobile device to the extender's default Wi-Fi network (usually displayed on the device itself), and follow the on-screen instructions to connect it to your main home network.
Web Browser Setup: Plug the extender into a power outlet. Connect your computer or smartphone to the extender's default Wi-Fi network (or via Ethernet if your PC is nearby). Open a web browser and enter the default access address (e.g., http://tplinkrepeater.net or an IP address like 192.168.0.254). Follow the setup wizard to connect the extender to your existing Wi-Fi network.
After the initial setup, you will then connect an Ethernet cable from the extender's Gigabit Ethernet port to your PC in the "dead zone" room.

SSID Management: Some users prefer having the same SSID (network name) for both the main router and the extender, allowing devices to "roam" between them. However, sometimes devices may stick to a weaker signal. If you experience this, consider giving your extender a different SSID (e.g., "MyHome_EXT") so you can manually connect to the stronger signal when in the extended area.
Conclusion
Your proposed solution of installing a TP-Link AC1750 Wi-Fi range extender in an adjacent room with good signal and then running an Ethernet cable to your PC in the dead zone is highly viable and effective. This approach intelligently leverages the extender's ability to boost wireless coverage while utilizing a direct Ethernet connection to provide your PC with a stable, high-speed, and interference-free internet link. It directly addresses the challenges posed by Wi-Fi dead zones, ensuring seamless connectivity for your critical devices. By following the recommended setup procedures and considering ongoing network optimization, you can successfully eliminate your Wi-Fi dead zone and enjoy reliable internet access throughout your home.
A traditional wireless-only Wi-Fi extender can halve your bandwidth because it has to receive and then re-broadcast the signal on the same wireless channel. However, by using an Ethernet cable from the extender to your device, as you propose, you mitigate this speed reduction for the wired connection, as the extender's Gigabit Ethernet port can deliver much higher speeds directly to your PC.
Where should I place the Wi-Fi extender for best results?
The ideal placement for a Wi-Fi extender is roughly halfway between your main router and the Wi-Fi dead zone. It needs to be close enough to the router to receive a strong signal itself, but also close enough to the dead zone to effectively extend coverage there. In your scenario, an adjacent room with good coverage is an excellent choice.
Can a Wi-Fi extender create a new Wi-Fi network?
A Wi-Fi extender typically extends your existing network, often using the same network name (SSID) as your main router for seamless roaming. However, during setup, you usually have the option to give the extended network a different SSID, which can be useful if you prefer to manually select which network your devices connect to.
Is it better to use a mesh Wi-Fi system than an extender?
For whole-home seamless coverage, especially in larger homes or those with multiple dead zones, a mesh Wi-Fi system is generally superior to a single extender. Mesh systems create a unified network with intelligent roaming and often offer better performance and easier management. However, they are typically more expensive than a single extender. Your proposed solution offers a cost-effective and highly effective compromise for specific dead zones.
