So I've just had the latest update for my HTC Desire HD. I'm running Sense 3.0 version 2.35. I was hoping this would fix my wifi error problem, sadly this has not been the case. I downloaded Wifi Fixer which will hold the connection as long as the screen is on but as soon as it turns off for any amount of time the wifi disconnects and the only way I can reconnect is by restarting my phone. Has anyone found a fix to the wifi error problem? If so please help!
