I've searched the forums for an answer to this problem, seems some others are having the same problem, but was unable to find a solution. Just today the WiFi on my touch stopped working for my wireless router. I can connect to the wireless network, but could not surf the net. Tried rebooting wireless router (linksys WRT54G), no dice. Tried several different DNS settings (IP of router, opendns, etc) to no avail. Also tried browsing too googles homepage using googles IP address at http://126.96.36.199, since this shouldnt be affected by DNS, still nothing. As a last resort i restored the touch to 1.1.1, no dice. additional, I have 2 notebooks running on same wifi connection, both working fine. additional additional, i have a webserver running on my local network, ipt connects to that no problem. any ideas?
