Data/WiFi conflict with ActiveSync?
 

For some reason, whenever my phone is connected via ActiveSync, I cannot make a data connection to the Sprint network, nor can I make a WiFi connection to my router. If I turn on the WiFi switch, the phone briefly activates WiFi, then turns it back off within seconds. If I have an active data connection and I then connect to ActiveSync (by plugging the USB into my computer), the data connection is immediately dropped.

Did Sprint change something in the last ROM update to make this happen? I know that this used to work. Has anyone else encountered this? Anyone know how to fix it?

Thought I had a broken wifi switch until I saw your post..... Same issue for me

Anyone.....

Here's something to check with ActiveSync that might have been missed after you upgraded your phone and re-synced it.

Open ActiveSync, then click on File->Connection Settings...

Is "Allow wireless connection on device when connected to the desktop" checked?

I don't remember ever noticing that checkbox before. It was not checked, so perhaps that will solve the problem. But I've never changed it before, so I still wonder if Sprint made some firmware change - perhaps they fixed it so that the phone now honors that setting.

In any event, it seems to have solved the problem. Thank you!

OK, I must be an idiot, but when I open ActiveSync, I don't even have an option/menu called 'File'
