stone walls and poor router signal

Heleus — Thu, 23 Apr 2026 17:31:44 GMT

Hi All,

I live in an old stone cottage with very thick walls (around 20 inches or more in some areas) - Inside the house my signal is ok, a little weak in some rooms but I can live with it. Recently I have had a Hypervolt EV charger fit to the outside of the house and this is where my problem starts. Connecting to the wifi is inconsistent and regularly drops out - my router is an older model (EE smarthub SH30A - I think it is wifi5 if that means anything??) and my connection is not full fibre but I think this has recently become available in my area, finally I am also using an old model of wifi extender, which is invisible to most devices through the stone walls.

So my question, I know obviously that an upgrade is required but do you have any suggestions? Would simply moving to full fibre and an upgrade on the smarthub fix the connection issue or should I look at changing to a mesh router system?

thanks in advance

Full Fibre won't make the WiFi signal any stronger, just faster in the places it reaches.

@Heleus Can you place a WiFi repeater very close to the EV charger? Your issue is the walls so the closer you can place it you might have a better chance. You can test this with your current repeater. You might need to use an extension cable to get it as close as possible but still within your home. From that you’ll know if adding an additional repeater as close as possible is an option to look at.

SH30A is WiFi 6 and to answer the router upgrade question: it's unlikely to help. Even if your EV charger supports WiFi 7 (which I'm pretty certain it won't), it's not really going to help with wall penetration. Likewise with an upgrade to a router that supports 6GHz; 6GHz is faster, but even worse at dealing with obstacles in its path.
