Why can't my phone connect to my WiFi

[jbrown]

iPhone 4s - recent replacement. iOS 6.

I had no trouble with the previous iPhone 4s.

I was backed up and I restored to the new phone. All good except when I try to connect to my WiFi network I get a message saying " Unable to join the network TalkTalk-XXX " the a dismiss option.

Any ideas?

Thanks

Is it just that wifi network you can't connect to, or is it all wifi networks?

My first 4s had a faulty wifi chip that caused it to be unable to connect sometimes and also ocassionally drop off whatever network I was on.

If you're having trouble connecting to any network, I'd take it back for another replacement. If it's just that network, then it might not be the phone.
