Extending Wi-Fi to the garage

Tomsdad · Monday at 17:02

Hi everyone, first time post. Not even sure if this is the right place but…..
I need to extend my Wi-Fi to my garage. My Wi-Fi is fttp giving speeds of 149 mbs download and 31 mbs upload. The garage is about 20 metres from the house and about 30 metres from the router. My supplier is currently PlusNet and it’s their router. The Wi-Fi needed in the garage is for an EV charger which uploads data to remote servers. So I think Wi-Fi strength more than pure speed is needed. The Wi-Fi at the charger is currently -75 db. but able to pair with the router using the wps button, but unable to upload any data so on the app it appears as offline.
Now I am absolutely no expert in this matter and all advise is welcome. I can think of three possible solutions
1. Wi-Fi booster
2. Powerline Wi-Fi extender
3. Running a networking cable from the BT fibre box on the house, to the garage then into a second router?? Is that even possible?
What do you people think I should do?

Thanks in advance.

Yes. The fuse box (distribution board) in the house has a dedicated breaker for the garage. Then the garage has its own smaller distribution board with a dedicated breaker for the EV charger.

Thanks for that. So I have just ordered TP-Link Wireless G.hn2400 Powerline AX1800 Wi-Fi 6 Kit, Range Extender/Wi-Fi Booster
Let’s see if that works. I’ll report back either way.
Appreciate your help.

I don’t know what an AP is.

Thanks for that. I think in the end it will be the Ethernet cable solution. So if I run an Ethernet cable from the back of my router into the garage, into a cheap dumb router it should work?
Maybe instead of the dumb router I can run the cable straight into the EV charger which has an Ethernet port.

Looking at these cable prices, it’s actually the cheapest solution. Just involves a bit of work burying the cable.
If I buy the external double sheathed cable made for burying, can Ethernet connectors be crimped on. Or does it need to go to a junction box and from there change to internal cable to crimp?
