I'm using Ubuntu 12.04. Network controller is BCM4311, lap top is a Dell Latitude D830. I've updated, upgraded, installed firmware-b43-installer, fwcutter, and it's still not detecting my wireless internet. iwconfig says no wireless extensions for lo or etho even though the controller is detected. Trying to manually add the wireless network through network manager also hasn't worked. It's just not detecting the wireless network.
And the output from lshw -c network:
*-network UNCLAIMED description: Network controller product: BCM4311 802.11b/g WLAN vendor: Broadcom Corporation physical id: 0 bus info: pci@0000:0c:00.0 version: 01 width: 32 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list configuration: latency=0 resources: memory:fe8fc000-fe8fffff
Output from rfkill list all:
0: dell-wifi: Wireless LAN Soft blocked: no Hard blocked: no 1: dell-bluetooth: Bluetooth Soft blocked: no Hard blocked: no 2: hci0: Bluetooth Soft blocked: no Hard blocked: no
What else can I try? All of the solutions I've seen have said that fwcutter and the firmware-b43-installer are the answer but they haven't been working for me.
