I have the BCM43224 (Dell Wireless 1520) installed on my Dell laptop (Ubuntu 11.10) and have compiled and installed the latest driver as per the README file at http://www.broadcom.com/support/802.11/linux_sta.php. I have verified that all conflicting drivers have been removed and blacklisted and that I am using the driver I compiled. The driver works and I can successfully connect to my router and the internet.

I am using the latest 64bit driver from Broadcom (see link above).

The issue that I have is that I cannot seem to get the 2x2 40mhz channel width to work in Ubuntu -- so my wireless link speed is less than half (at best) what it is in Windows 7. I have successfully done this on the same computer through Windows 7, and am able to achieve full speed (upwards near 300Mbps).

Is this a known issue with the current Linux driver? Is there any way to enable 40mhz channel width in Linux?

I would greatly appreciate any help you can give me!

Hmm the BCM43224 should be supported out-the-box on the in-kernel brcm80211/brcmsmac drivers. Is there a reason you went to the STA drivers? – Oli♦ Nov 10 '11 at 16:40
