Hello; I have a new iPod Touch 3G, and I'm getting poor WiFi performance. Sometimes websites will load quickly in Safari, sometimes they take forever. Can't login to apps like Pandora and Slacker, eventually I get a message like "cannot connect, check your network settings." I was able to load the App Store after a long time, but have not yet been able to get the iTunes app to load. If I ping my iPod Touch, I usually either get lost packets or a very long ping time ("latency"?). Before I return this, is there any way I can diagnose exactly what's going on? Thanks in advance.
