We have a wireless network in our house and since yesterday it has not been working and i was wondering if anyone could help me. Initially two of the three computers said there was limited or no connectivity so we restarted the router and now all three computers connect and say there is a good signal but none of them can access the internet. The data button isn't flashing on the router so i was wondering if it was a problem with the service provider. Does anyone have any suggestions? I've been trying to phone the helpline but there is at least a 25 minute waiting limit and i haven't got through yet.
