Thread: Phone connecting to wifi but not being able to use it

I've had the phone for about a year and it's always worked before. It just seems to have suddenly stopped working. I've tried rebooting it, taking battery out whilst it's turned on, forgetting the network and then re connecting. It's not in airplane mode and funnily enough the internet works fine using the mobile network. Please help. The only thing I can think of is we've just got a new computer which we've attached to the wifi. But I don't see why this would make a difference. My partners phone works fine as does the 2 computers and the printer.
