Larry,
I've got it working and here's the scoop after many hours.
the only version that's officially compatible with windows 8.1 is the AUus036nhr model.
I just happen to have this when I replaced one that broke about 1 1/2 years ago.
As for the crashing, after I installed the software, per instructions, then plug in the
antenna, I got a blue screen, saying windows had a problem, and would restart.
once restarted, it would again say windows had a problem and would restart. this would
continue until I unplugged the antenna.
I found that the updated software could be downloaded from www.realtek.com.tw/downloads.
downloaded and installed, and works great. I'm a happy camper.
Also, after talking to data alliance, I contacted alfa tech support via e-mail. they responded
within a couple hours, and then also responded in similar fashion a few times. very helpful.
