I have a wireless G linksys router. Pretty standard. And when I got it all hooked up it worked great for a few hours. Now, since yesterday, my ipod will load pages and everything fine for about an hour to 2 hours and then it'll just be stuck at "loading." It doesn't say it can't find server it and it can recognize it because it shows up under wifi spots. I will unplug my cable modem and router for 30 seconds and turn it back on and it'll work for an hour again or somestimes if I just wait a few minutes it'll just start working again, but I don't want to have to do that constantly. Is there a router setting that I need to fix or anything?
