Ubuntu – Can’t connect to Wifi 5GHz with Broadcom Corporation BCM4311

14.04broadcomnetworkingwireless

I am using b43 driver installed via synaptic package manager and I have loaded the module through command line “modprobe -r b43 bcma”.

The wifi indicator on my pc light up and the wifi manager shows many available wifi networks but my 5GHz network is missing. All other mobile devices and workstation are connecting to this network without any issue.

I have tested brcmsmac bcma and wl module but only b43 seems to work with my wireless card => Broadcom Corporation BCM4311 802.11a/b/g [14e4:4312] (rev 01) .

NOTE:
My PCI device is listed as supported => http://www.linuxwireless.org/en/users/Drivers/b43/#supported and I can connect to the same network with the same workstation if I boot with Windows 7.
I am trying to connect to router Technicolor TC7200.

Question:
It is obvious that the old b43 driver doesn't recognize the 5HGZ access point, is there any other approach how to get this work?

Best Answer

5GHz is NOT supported by broadcom-wl or any other driver choice. Sorry, but look here
