How to Improve Your WiFi Signal with a Repeater and Ethernet
Struggling with weak WiFi in certain rooms of your home or rental? You’re not alone. Many people deal with WiFi dead zones where the router signal doesn’t quite reach. During my last vacation, I ran into this exact issue—the internet connection barely worked in my bedroom. Instead of dealing with slow speeds and buffering, I used a simple WiFi repeater and an Ethernet cable to extend WiFi coverage and boost performance.
Here’s how you can do the same to fix weak WiFi signals at home.
Why WiFi Repeaters Can Save the Day
A WiFi repeater (or extender) is one of the easiest WiFi dead zone solutions. It captures your router’s signal and rebroadcasts it into areas with poor coverage.
However, many people simply plug in a repeater and expect strong results. While this works to some extent, it often leads to slower speeds. With the right setup and placement, you can boost WiFi strength and enjoy a stable connection for streaming, gaming, or video calls.
The Best Way to Extend WiFi Coverage: Use Ethernet
Most users connect their repeater wirelessly to the router, but this method reduces speeds and creates more interference. A better solution is to use an Ethernet cable.
In my case, the rental had a wall Ethernet port. By connecting the repeater via cable instead of WiFi alone, I created a direct link to the router. This gave me a stable connection for streaming and eliminated buffering issues.
Why Ethernet Beats WiFi in This Setup:
- Avoids signal interference.
- Keeps the full internet speed when extending the network.
- More reliable than wireless-only setups.
This Ethernet vs WiFi connection method is the best way to maximize your home network performance.
Choosing the Right Ethernet Cable for Better Internet Speed
Not all cables are the same. The cable category affects speed and stability. If you want to increase internet speed at home, upgrading your Ethernet cable might help.
| Ethernet Cable | Max Speed | Max Transfer | Frequency | Best Use Case |
|---|---|---|---|---|
| Cat 5 | 100 Mbps | 15.5 MB/s | 100 MHz | Outdated, avoid if possible |
| Cat 5e | 1,000 Mbps | 150 MB/s | 100 MHz | Affordable, works for most homes |
| Cat 6 | 1,000 Mbps | 150 MB/s | 250 MHz | Great for repeaters and everyday use |
| Cat 6a | 10,000 Mbps | 1,250 MB/s | 500 MHz | Gamers and heavy users |
| Cat 7 / 7a | 10,000 Mbps | 1,250 MB/s | 600–1,000 MHz | Advanced home networks |
| Cat 8 | 40,000 Mbps | 5,000 MB/s | 2,000 MHz | Future-proof, professional setups |
Tip: Cat 5e or Cat 6 is usually enough for most households. I personally used a Cat 6 Ethernet cable, and the difference was noticeable.
WiFi Extender Setup Tips: Placement Still Matters
Even with a wired connection, choosing the right location for your repeater is crucial. Poor placement can lead to weak performance.
Here’s how to find the best place to put your WiFi repeater:
- Place it in a central area for balanced coverage.
- Avoid interference from Bluetooth devices, microwaves, or other electronics.
- Don’t hide it behind furniture—it needs open space.
This small adjustment can improve router signal strength and ensure your extended network performs well.
