Hello all, I made an account to post this reply since I also have been frustrated with the frequent crashes.
I have an Aviptek NC1200W, which is technically equivalent to the Gadspot one.
I downloaded FW version C61200-WX-2.00.02.70929-ZZ
from
http://www.aviptek.com/nc1200w10.html
I could started getting the hangs after 30 mins and even wrote a script that rebooted the thing every 15 mins, but that didn't help.
I then held the reset button (little hole in the front) for over 30 secs to reset the default settings.
After reapplying my regular settings, it started working well and hasn't crashed in over a week and a half. I am only using the wired connection though, with the wifi off.
Hope this helps...
Also, I can now get to the jpeg and mjpeg images in Linux.
I set up lirc so that when I press a button on my remote control, it starts
vlc -f --video-on-top

which shows the camera output on my computer
