I recently installed openSUSE 12.2 on an MSI VR420 laptop (model MS-1422). Since it is a laptop, I elected to go with the Network Manager applet rather than using ifup/ifdown. Fortunately I configured it as a dual-boot machine and left the existing Winows Vista Home Premium OS in place.
The problem is that frequently on bootup after a reboot or powerdown Network Manager will report "Wireless disabled by hardware" even though the LED for the radio is illuminated. Indeed, the Wireless LED will toggle by repeatedly depressing the wireless switch. The only way I've found to get the WiFi to work when this happens is to reboot into Vista and login so that the WiFi connects to an AP, then reboot into openSUSE. The WiFi will then work and connect to the AP.
Interestingly, I can get the same message when Wifi is working by pressing the wireless switch and extinguishing the WiFi LED.
I have tested the memory extensively using Memtest86+ and the memory test portion of the Vista System Recovery S/W, No errors have been found.
Still, SOMETHING is causing a bit to flip somewhere on openSUSE reboot/shutdown and that bit stays flipped through multiple reboots and removal of the battery and power cable.
If there's some way to re-enable the WiFi in software (preferably from the command line) I'd like to know it.
Here is the output of "hwinfo --netcard" when WiFi is working and when it's not. In both cases I cut out the portion that relates to the onboard Gb wired NIC.

I'm beginning to think that this is a bug in the rt73usb module, as it seems that the same thing happens when booting a LiveCD (like PartedMagic).
I appreciate any help you can offer. If you need more info let me know.
Thanks,
ron
