I've been experiencing this problem for awhile now and have contacted BT about it but nothing has really happen much. This has been occurring over the last 4 months where anything connected via Wi-Fi is really slow. Wire connection is fine and I've not had any issues with it. I was advised to try different channels set on my router to which I tried all of them and the issue still occurred (was fine on automatic previously). Wi-Fi has been fine for years but has only started playing up over the past 4 months and nothing has changed so I can't see it being an interference issue. I have the home hub 3 and a modem. I have been restarting my router overtime I have an issue which doesn't help. I'm thinking about getting one of the new BT home hubs as it's looking to me being a fault with the router but I'm hoping someone can give me some other options to try.
