My Desire HD connects to my wifi, shows full signal, and allows me to access web pages and web through apps as normal. After about 5 minutes, all web pages and requests time out and I no longer have internet access, although my phone still says I have full Wifi signal and I've received no errors other than "this page doesn't appear to exist" kind of thing. I don't seem to have this problem on my works wifi - get full internet access as normal. My girlfriend's Desire S doesn't seem to have the same problem on my home wifi. I've tried turning off 3G, and I've tried setting a static IP - I get the same issues with both. I've used Wifi Analyzer and set my wifi broadcasting channels to ones set outside the ones used by all of the other routers I can pick up. I've already received the Desire HD wifi fix update as well, didn't seem to make any difference. Any help would be appreciated!
