solamour,

Does the device ID change between a cold boot and a warm boot?
Or easier to test, does the device ID change when the kernel module and fimware is loaded?

The differece between the two boot states is that at a cold bood the card gets a hardware reset pulse and in a warm boot, it does not.
Theory ... reboot trashes the firmware installed but does not revert the device ID to the pre fimware loaded state, so its not reloaded on reboot.

I wasn't quite sure how to check the device ID (inform me on how to go about doing that), so I just did "lspci -vvv" when WiFi is working and not working.

Code:

The only difference between the two are the following
Code:
WiFi Working:
Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort+ <TAbort- <MAbort- >SERR- <PERR- INTx-
CESta:   RxErr- BadTLP- BadDLLP- Rollover- Timeout- NonFatalErr+


Code:
WiFi Not Working:
Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx-
CESta:   RxErr+ BadTLP- BadDLLP- Rollover- Timeout- NonFatalErr+


Quite honestly I have no idea what this jumble of texts means, so if there is anything you'd like me to test, just let me know easy-to-follow instructions. Thanks.
