[solved] Error compiling wpa_supplicant with broadcom_wl support

Hello friends.

I'm using the broadcom_wl driver for my bcm4312 card in my Dell XPS m1530 laptop. Unsecured wifi is tested and works fine.

I need to use wpa_supplicant to connect to my university's wifi. The core package for wpa_supplicant is not compiled with broadcom support. I tried using the generic wext option, but I get

Trying to associate with 00:11:92:90:de:e1 (SSID='restricted.utexas.edu' freq=2462 MHz)
ioctl[SIOCSIWAP]: Device or resource busy
Association request to the driver failed

It looks like the generic wext option doesn't work for the bcm4312.

So I tried to compile wpa_supplicant with broadcom support using ABS with this package: http://aur.archlinux.org/packages.php?ID=18511 from AUR. I enabled broadcom support in the config file and pointed it toward my local copy of wlioctl.h.

Unfortunately, build() dies with

I don't know c. Can someone decipher this error for me?

Thanks in advance.

EDIT: There are multiple versions of wlioctl.h floating around. I eventually got this to work with the version included with the wrt54g tarball. BUT, wpa_supplicant still had driver problems when being run with the -D broadcom option.

I eventually got this working with ndiswrapper and instructions found here: https://help.ubuntu.com/community/WifiD … y_No-Fluff
Pay special attention to the instruction:

"This Chipset/PCI ID is the correct/reliable way to identify the device: Any other labels can be misleading (e.g., notice that both the '14e4:4311 (rev 02)' and '14e4:4319 (rev 02)' call themselves a "BCM4311 (Rev 02)", even though they are different devices)."

Download the driver that matches the output of

lspci -n | grep '14e4:43'

Anyway, wpa_supplicant still gave me driver troubles when using the -D ndiswrapper option. However, it works well with -D wext.

Tldr;
-Your bcm4312 may actually be a BCM4310 (rev 01).
-Use ndiswrapper with this driver: http://myspamb8.googlepages.com/R174291-pruned.zip
-use wpa_supplicant with the -D wext option.
