YES...I have this very problem. At times, my Focus has trouble connecting to wifi, and at times when it is connected it actually uses 3G/3G+ and then the connection
In my case the 3G isn't bad, and neither is the wifi...if i turn of either Cellular data or WIFI then the other will work just fine for data. It is as though the phone has trouble switching between the two.
Finally, I have talked to a couple HTC Radar owners with the same problem in another forum. Besides having Mango in common, we all think it might be related to using Internet Sharing (which I 'hacked' onto my Focus). Do you have the Internet SHaring hack on your Focus?
