I've got Plusnet 76Mb fibre, with the BT openreach modem and the Technicolour router. I've written in the past about wifi problems but for the past few weeks it's been good and I've been getting 30-50Mb wireless speeds all over the house which is fine.
This afternoon some children came to the house and one of them pulled some of the wires and loosened them and the internet connection went down. I plugged everything back in and rebooted the router but there's now a big wifi problem.
I get 70+Mb speed with ethernet. If I put the laptop a few feet from the router I get 40-50MB wireless speeds. But there's almost nothing in the rest of the house. Walk a few feet away from the router and the wifi suddenly drops speed. Can get 1Mb in the front room but no wifi connection anywhere else. The front room used to get 60Mb with wireless until today.
I've tried different channels, to no effect. I suspect this is a hardware problem, i.e. the router got damaged when the child pulled the wires. Any ideas? Should I buy a new router?
