we have been having problems with our wireless internet connection for a while now and have even changed provider without success.
What happens is that all our computers lose the internet connection from one moment to the next while the signal strength remains unchanged. when you try to sign back into the home network it is basically impossible. When rebooting the BT router it works, sometimes for a few moments only sometimes it lasts.
I am wondering if the reason is that the computers are losing their ip address or has it something to do with the security key?
