I have been trying to get this wireless card using Broadcom BCM5751 chipset working, but it is just giving me frustration. This is using the tg3 module.
What have I tried so far:
Play around with the default kernel module. Yes, it shows the available wireless networks but will not connect. I'm currently in net through wired connection, using the same tg3 module.
Download the linux driver from Broadcom's website. The package comes with .rpm and .tar.gz drivers, no .deb. Extracted the .tar.gz, and followed the README. Tried to compile the driver, but compile fails.
Installed ndiswrapper and downloaded windows drivers (tried with Vista and XP). Result:
sudo ndiswrapper -l b57nd60x : invalid driver! b57win32 : invalid driver!
