Broadcom BCM4312 - Updated Firmware, now no wireless in Windows

[Imizael]

I just tried 10.10, and aside from the ever-present wireless issues, I was okay with it. Unfortunately, I require wireless access to work, and it didn't work out. I removed the Ubuntu partition, fixed the Windows bootloader, and booted back into Windows to find that wireless no longer works.

Now, when I was in Ubuntu, I installed firmware-b43-lpphy-installer. I suspect that installing that overwrote whatever I had before as far as firmware goes, and the driver I have in Windows doesn't work. Now, when I say "doesn't work", I actually mean "detects and installs properly per Device Manager, but doesn't actually detect or connect to wireless networks."

I'm going to try using a liveUSB installation to reinstall the default firmware... if I can figure out what that is. I looked for a Windows firmware installer for the BCM4312 chip, but I can't find one. Running the manufacturer installer (Dell Inspiron 1564) worked, but didn't get any different results.

Does anyone have any suggestions?

What wifi issues?
My Mini has the same card (I presume):

03:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g LP-PHY (rev 01)

It works well if you use the ubuntumini link Megaptera gave in 10.10. The other driver (b43) appears to work well initially, but intermittently disconnects.

As far as I know, the firmware makes no changes to the hardware at all - so it should have no effect on Windows.

Perhaps point 9 in this link might be of relevance? http://ubuntuforums.org/showthread.p...25#post5024425
Although a re-installed Windows should be able to fix its own ridiculous setting.
