Extending wifi

[clutha]

I have two Ring devices, gen2 doorbell & stick up camera.

Our flat is on the 1st floor in an 1850’s house, thick walls. 
Door bell is external on ground floor. It has worked well for almost  3 years.

A couple off weeks ago the WiFi signal became intermittently too weak to stay online.

I suspected interference from other flats.

BT sent me a Black Disc, it won’t connect either by WiFi or ethernet, goes back to Red light.

Another Disc was supplied, same result, no. 3 arrived today, not tried yet. A BT engineer was booked to come this morning. Cancelled by BT 15mins after appointment time.

Getting somewhat frustrated.

Meanwhile ‘Stickup Ring camera performs fine via £20 TP WiFi extender. This used to connect door bell but started failing a couple of weeks ago 🙄

The problem with a wi-fi extender in your circumstances is where would you site it?

You might be better off, as a first step, changing the 2.4GHz band on your hub, there's only 3 channels to choose from on a BT hub so you can do it by trial and error

Thanks for reply, presently trying to set up disc 3!
Following BTapp method.
I’ve tried channel change on hub as advised by BT help line, they recommended 2.4 🤔
