iPod Touch will not connect to WiFi network
I am getting errors connecting to WiFi networks with my iPod Touch. This had affected a Touch I got a couple months ago. Initially, the WiFi worked perfectly on my WEP network and several others. Then, one day, I couldn't get any WiFi. After standard troubleshooting steps (forget network & re-enter, reset network settings, restart, restore iPod, etc.), it still wouldn't work. I returned the iPod and bought another. At first it also worked perfectly on any WiFi network I joined.
But now I'm affected by the same issue. This time, I went to the router settings and saw that the router (a Linksys) had assigned the iPod Touch an IP address. Yet, in the settings pane on th iPod Touch, the iPod had no IP address. I just ahead and reset all network settings, forget the network, reset the update and still nothing. And this was recently after updating to 1.1.2 firmware.
Given that this has now happened to iPod Touches, I'm concerned that it may be an issue that is affecting others. Any suggestions? The error I get in Safari is "Safari can't open the page because it can't find the server."
