Up until 1.64, I was havng problems where my SB server would die and not be found by my SB radio. I installed 1.64 and the server worked for a couple of days and then all of a sudden it was not seen AT ALL by the radio. I tried restarting the server, cleaning the cache and restarting the LSWXL without any luck. It wasn't until I set the LSWXL back to factory defaults that the radio found the server.. Since this happened, the radio has upgraded its own firmware twice. It's been working really well for more than a day without any problems (a new record)! I'll add any new findings to this thread.
