Hey I just wanted 2 throw this out there in case it might help anyone else. I've been using my iPad 2day with our WiFi and its been okay but pretty slow actually. It's stalled a couple of times but never really disconnected (just sometimes took a long time 2 open web pages or whatever).
Anyways, I noticed something really interesting. Even tho the WiFi was working, I went into the settings and turned off auto-brightness and WOW. All of a sudden (and instantly) I got a HUGE performance improvement with WiFi. My web pages are opening hugely fast now and my comics downloads (was gettin some comics from the Comixology "Comics" app) were super fast compared to what they were b4.
It SEEMS that just turning off auto-brightness made this big improvement. If anyone else is having slow WiFi issues can u try this and see if this works? It would be really good 2 know for peeps who are having slow connections.
