Hi,
From web searches I can see this is a common problem. My phone and iPad remain connected to wifi but frequently (several times per day) lose connection to the internet. I know this only because web pages time out. If I disconnect and reconnect wifi the connection is restored to the web. Other devices not affected to my knowledge.
I think it might be worth trying a firmware update, which I believe Talk talk can initiate remotely? I have a fairly old router, had it for 5+ years.
thanks!
