Query: Locks up, constantly needs to be rebooted

The DWL-G820 has given me nothing but problems. The unit constantly locks up forcing you to reboot it, but then it loses all of its settings and reverts to defaults. Sometimes it takes 2-3 reboots for the unit to become functional again. My friend bought one and he has also experienced nothing but trouble. I am sure that the problems are all firmware-related, but D-Link has not released any new firmware revisions (1.00 is still posted on their site).The only other issue I have is that it runs very hot - much hotter than any of my other networking equipment (my friend's unit also ran very hot). They could also lengthen the antenna a bit, I think it's just too short.
