I upgraded my Mini9 with an Atheros 5008 card manufactured by AzureWave. No problem with the install and everything seemed to work fine. I primarily use my Mini9 to stream video with a Slingplayer. It works fine for somewhere between 45 minutes and an hour and a half at which point it always bluescreens with a message "NMI: Parity Check/Memory Parity Error." It's definitely not the RAM, because only switching back to the stock 802.11g fixes the problem. Searching the web suggest it's a defect in the adapter, but I'm not sure it's not a compatibility issues. Has anybody else had a problem like this and do you have any suggestions? Thanks.
