I changed to infinity about april/may this year and have constant problems. The longest running is not being able to connect to the internet at all. diagnostics on my computer says "wi-fi does not have a valid IP address" it re sets the router but this mainly fails. i usually have to re set it at least twice before it will connect at all, today it took 3 attempts.
I have had several faults on my line which the fault reporting page says are fixed. but I see no inprovements on a day to day basis. some days everything is painfully slow even by my old hubs standards. A week ago I lost both broadband and landline connections. A workman was in the street with an open reach van. I asked him if he was with BT - he said they had come to change my cable, so they dug up the road and took most of the day. I was not informed of this and it does not show up on fault reporting page. It has made no difference.
I dearly with i had never joined. the saleasperson assured me the only difference I would see was very fast speeds but so far i have seen nothing but problems and i'm still beeing charged. I have not got the caller alert even though I have this new line contract. A chat helper assured me it would be turned back on but still no joy - fancy that!
I have screen shots and chat transcripts to back this up
The no valid IP address can occur if your computer network adapters have been corrupted. You will need to uninstall them and reboot your computer.
If using Win 10 then do this
I have found that uninstalling the ethernet adapter solved my problems with both the wireless and wired connection on my laptop.
It'll be almost the same.
It is probably not a corrupted network adaptor if resetting the Homehub resolves the problem.
Try ONE factory reset of the Homehub by pressing a pin into the recess button on the rear for about 20 seconds.
Follow the below instructions:
I hope using these steps your problem will be resolved.
