So at first I thought the upgrade to 2.2 had fixed my wifi issues as I was able to connect to my wireless N router with TKIP/AES and was getting speeds of 10-15mbps but since the first day or so it's been sporadically not working. It still shows it's connected with signal bars but no data is coming through. My Touchdown exchange email which polls every 5 minutes starts to show failures and webpages fail to load. If I log off the wifi and then back on it SOMETIMES fixes the problem. I've also tried to change my router to wireless G only with TKIP and I'm getting the same issues. While it's better than 2.1, it's still not usable everyday. Anybody else having these issues? I'd love to have wifi work correctly like it does on my iPod touch as it'll save battery, give me faster speeds, and allow me to use the web and get notifications while i'm on the phone.
