Thick brick walls can kill WiFi signal, especially in older UK houses and extensions. The right extender can make a big difference without a full mesh overhaul.
We’ve picked compact, reliable options that are easy to set up, with a mix of budget, mid-range and premium choices for stubborn dead spots.
Our Top Picks
£20-£30
TP-Link RE315 AC1200 WiFi Range Extender
“A cheap and simple way to push signal through awkward brick layouts.”
The RE315 is a solid budget extender for smaller homes where one or two rooms lose signal. It uses dual-band AC1200 speeds and a handy signal light to help you place it properly.
Build quality is basic but fine, and setup through the TP-Link app is straightforward. It’s best for boosting coverage rather than delivering top speeds through multiple thick walls.
- Very affordable
- Easy setup
- Good signal indicator
- Limited top speed
- Not ideal for large homes

It is larger and pricier, but the build feels more substantial and the coverage is generally more consistent. It suits users who want a sturdier, higher-capacity extender without moving to mesh.

- More expensive than entry-level models
Best for: Larger homes needing stronger, steadier extension across brick walls.

ASUS RP-AX58 AX3000 WiFi 6 Range Extender

It is well built, faster than cheaper units and better suited to demanding homes with multiple thick walls. The higher price makes sense if you need performance close to mesh without replacing everything.
- Fast WiFi 6 performance

What to Look For — Buyer’s Guide
What matters
With thick brick walls, placement matters as much as the extender itself. Look for dual-band or WiFi 6 models, and position the unit where it still gets a strong signal from the router.
If your home has several heavy walls, a mesh system may work better long term. Extenders are best when you only need to fix one or two weak rooms.
Our Verdict
For most UK homes, a good WiFi 6 extender offers the best balance of price and performance. If your brick walls are especially stubborn, it may be worth stepping up to a stronger premium model.
