Dell Streak problem:

My Streak has started freezing.  Side lights stay lit - that's it.  Finally dies - then recharged it.  After this issue three times, now it will not connect to my internet.  Continuously Scans - Authenticates - Disconnects - Scanning.....  All other wireless devices are working fine.  Since the last "freeze" it won't connect. Please help.  Warranty will be up in mid December.
