Hello there, I'm wondering has anyone else had this problem with their wi-fi. My iPod Touch was working well with my home wi-fi network for the past few weeks. Then about three days ago it suddenly stopped. I can connect to the network, but whenever I try to do anything online I get an "Invalid Argument" error. I thought my wi-fi thingy was faulty, but then I borrowed a friends net book and he was able to connect to it without a problem. I noticed one thing, the ip address that showed up on the net book was different from the one on the iPod. I tried to manually enter it, but the iPod seemed to forget this as soon as I left settings. Is there any way to make the changes stick? Has anyone else had this happen to them, if so, how did you fix it? Thanks in advance.
