Hope this solves ur WiFi problems! I was, well I thought I was, having trouble with my WiFi connection, I was so pissed n almost exchanged my iPod 4 a new one, bt then I did this: I called my internet service provider, talked to a representative, and explained the issue. I let them do their thing and at the end they provided me with the name of my wireless or WiFi network and my WEP key. N thats it! So I went to setting in my iTouch n joined my network n for my password i entered the WEP key they provided, and it worked! Now I don't get that ugly "can't find server" pop-up and I have excellent signal. So, call ur internet provider, explain ur issue, and ask them to provide you with the name of your network and your WEP key. Hope this works. Post here if u have any questions and/or u were able to get into internet after doing this! Good luck!
