I have this Thinkpad E335, it is quite a legacy model now but I decided to give it to my uncle for some fun. I recently found the wireless drivers cannot be recognised (a exclamation shown) in WINDOWS 7 no matter which driver I downloaded from Thinkpad official website. (It did work previously).
I remembered I did upgrade the bios (it is also from official website), and after that it seems the wireless driver does not work. However, if I installed ubuntu, the build-in driver works. This means the hardware and bios work but the problem is the driver?
Where can I found a driver that works or how can I downgrade to an older version Bios.
Thank you for the help.

For wifi cards, they're usually PCI devices so the format is PCI\VEN_xxxx&DEV_xxxx&&SUBSYS_xxxxxxxxx
The parts in bold are the most important ones (VENdor ID and DEVice ID), google that part until you can find a proper name for the device. Once you've found its name, it's much easier to look for drivers.
