If you go to Manage Connections page again, you will most likely see that the check box next to Mobile Network is unchecked, with a red X. Your Wi-Fi should now be on with a green check box. Exit out.
You should also see UMA in upper right corner, and now should be able to access your Wi-Fi network. In order to get back to EDGE, you need to go to Manage Connections again and undo the above.
I don't know why, but my Curve seems to attach to the EDGE signal at my home, and UMA only if I manually turn off EDGE signal.
options > mobile network > connection preference. set this to "wi-fi preferred", hit the back key, select "save", then hard reset the device by pulling the battery while the power is on. wait 30 seconds and put the battery back in.
if this doesnt do it, then it means you have an unusually strong mobile signal near your home (like, you live under a cell tower) and/or your wireless router's signal output has much to be desired.
