I've had Virgin internet for years and never really had a problem. Then a few weeks ago the wifi started to cut out, the wired connections stayed fine. I checked the channels and saw that both mine and next doors routers were both on channel 6 so I tried mine at both ends of the scale 1 & 11 but the problem remained.
I contacted Virgin and they arranged for an engineer to swap out my router which turned out to be faulty (shit happens) so I kicked off and they sent another engineer with one of the new AC routers. So what is happening now, is wired is fine, 5G is fine but the 2G starts off OK then intermittently the speed starts to degrade till it gets to 0. I've tried stepping through various channels but the problem remains.
It doesn't really affect me as 95% of the time I'm on a wired connection but my daughter is driving me nuts as her laptop only has a 2G connection.
I'm stuck now and don't know what else to try.
