Ongoing issues with multi room v6 box
I had an additional V6 box fitted in the bedroom a few months ago, but I've been having intermittent issues where it says that my connection is too slow or that the bedroom V6 box can't connect to the main V6 box down stairs.
After a lot of back and forth I was put through to someone in retentions said the if you could be because my kit was old.
Virgin sent out a new router (hub3) which is the same as the one I already have, the engineer said no point changing it as its exsatly the same.
An engineer came out who said that the signal was poor and kept dropping (i can't remember the actual words he used)
He fitted an signal amplifier and said it was miles better when he tested it.
That same night I had an issues with the Wi-Fi on my phone where page wouldn't load and then the v6 box in the bedroom had the 2 flashing arrows.
After a lot of messing about the V6 box in the bedroom was able to connect.
The same thing happened the next night and I was unable to watch anything from the downstairs V6 box on the V6 box upstairs. it was also playing up when trying to watch catch up.
Error codes:
V401, N17, V125, V210, C501
Could someone technical please help as whenever I ring Virgin they just try to flog me extra stuff.
