I've done all that was suggested in this thread (except the HP Connection manager one) and I'm still getting the same issue.
The only thing different I have to report is before I tried reinstalling drivers, the button turned blue for just a second when I would re-enable through device manager. After reinstalling drivers though... it no longer does this.
I've also swapped out the wireless card with another one of same brand and model but still nothing new.
Laptop is Compaq CQ60 with BIOS F.54 and is using Win7 32-bit
Wireless card is Atheros AR5007, driver version 2.0.0.74
