Wi-fi connection problem

[#1]

I lost my wifi connection at home for a couple of days and when it came back I haven't been able to connect on my W995 phone, which had no problems before.  I can connect with my notebook no problem.

I've used the wifi on the phone elsewhere and it's been fine so don't know why it's not working at home.  It says I'm connected but I get a communication error message when I try to browse.

Have checked setting and can't see what's wrong and it's driving me mad!

Any ideas?

Thanks.

Delete the connection from the phone, power down the router/PC, turn power back on and reconnect your phone.

Thanks for the advice.  Tried that and lost connection on the notebook too!

Turned out to be a problem with the hub which Virgin sorted out so I'm back in business.

Thanks anyway.

No worries.
