Wireless does not work anymore after software update with Ubuntu 12.10 on a Dell Latitude E6230
- by Andy
I just installed Ubuntu 12.10 on my DELL Latitude E6230, on first boot wifi worked properly but when I updated the software it stopped working. I can't figure out the problem...
The wireless network controller is a Broadcom Corporation BCM4313 802.11b/g/n Wireless Lan Controller (rev 01)
"lshw -class network" gives, for the above controller:
*-network UNCLAIMED
description: Network controller
product: BCM4313 802.11b/g/n Wireless LAN Controller
vendor: Broadcom Corporation
physical id: 0
bus info: pci@0000:02:00.0
version: 01
width: 64 bits
clock: 33MHz
capabilities: pm msi pciexpress bus_master cap_list
configuration: latency=0
resources: memory:f7d00000-f7d03fff
After reading the answer to another similar question, I edited the file
NetworkManager.conf to make "managed=true", but that did not make any difference,
it is as if the wireless adapter were not there. In the "Network" setting window,
I only see "Wired" and "Network proxy". Wireless has just disappeared:
rfkill list all
0: hci0: Bluetooth
Soft blocked: no
Hard blocked: no
and that's it! Nothing about the wireless controller...
Any suggestions?
