I had full fibre provided about six months ago, the router is now on the first floor of our four bed house. To improve WiFi coverage I have a TPLINK range extender. This has worked reasonably well until recently with only a couple of areas receiving weak to no coverage.
I wanted to improve the arrangement to get full house coverage, first by mapping using a phone app. What I found is that I get 150 mbps throughout the property for a few minutes but then it will drop out with only coverage at 150 mbps in the imeadiate vicinity of the router leaving most of the house without a signal.
I'm puzzled is the router faulty? Is that normal? Do I need to install more or new WiFi range extenders.
I used the Sky service checker and got a clean bill of health. I would appreciate some help, as as a consequence of the regular loss of coverage a number of smart plugs are no longer operating.
