Home tech expert visit yesterday for installation of latest home hub. We didn’t want complete wifi as well (as only power line extenders work in our house; sky q etc doesn’t work here) but he convinced us to give it a go. He left without it working properly (he had been here 2 hours to be fair and it was 8pm on a Friday ) and we can’t get a signal in the lounge or upstairs. We had tp link power line extenders before and I think we’ll have to go back to using them. Anyone else had this problem?
