Hello, I have a Dell Vostro running Ubuntu 12.04 with a Broadcom BCM4313 wireless card. I've used linux a fair bit but I'm far from a guru.
The other day, I noticed that whenever my Ubuntu laptop was the wifi network, all the other nearby machines experienced problems. After some research, I found people saying the proprietary STA drivers could cause this problem and should be disabled.
I uninstalled the STA driver package and de-blacklisted bcma, brcmsmac, and brcmutil in /etc/modprobe.d/blacklist.conf per some instructions I found. After a reboot, my wifi worked fine again, presumably now on the open source driver. (Notably, ifconfig now called my wifi interface wlan0 instead of eth1.) I even found it a bit faster to connect.
I used the machine normally for a day or so. Then today, some bizarre message about "Precise" popped up unexpectly. I'm afraid I didn't read it thouroughly, but it said something about Precise not being supported anymore and asked if I needed technical support. Lacking context, I dismissed it. However, after a reboot, wifi is no longer showing up at all in the network manager menu.
The ethernet port on this machine was destroyed some time ago, so for the moment I'm sharing internet through bluetooth from another machine.
I'm hoping someone can help me out with this problem. I'll reinstall the STA driver if I have to, but I would prefer another solution.
Here's the output from some relevant commands...
