12.04 does not detect wlan0(Broadcom 4365)

Today I acquired a Dell XPS 1645. Ubuntu seems to run alright on it however The bluetooth is not detected and the WiFi doesn't work. The WiFi is especially weird because I actually have the restricted driver enabled for it. It also worked for a short while when I first booted into Ubuntu however now there isn't even an option to enable wireless.

My laptop (Dell Inspiron 17R 5720) came with preinstalled Ubuntu 11.10. I removed it and installed 12.04. Now I can't find driver for wireless. Apparently, in 11.10 there was Broadcom-STA driver. But in 12.04 there is no additional drivers to install. I tried using:

sudo m-a a-i broadcom-sta

But building fails on 26%.

I'm new to linux. I just started working on ubuntu 12.04. Wifi is not working on ubuntu. It works on Windows 7 though.

When I tried connecting to the net throght LAN it works. Also, through LAN I checked for additional drivers.

Hi,

I bought Dell Inspiron 15R (5520). It comes with Dell Wireless 1704. The chipset is Broadcom 4365.

I used this package to install the driver on 3.2 Kernel and it was working perfectly.

I had a solid bluetooth connection to my mouse with my built-in bluetooth on the Dell Inspiron 1525. I had installed a game and when I exited out, the bluetooth stopped working. Instead of just rebooting the system, I removed bluez and reinstalled it, but it still did not work. Now I'm stuck without a bluetooth connection or icon at the top.

Hi I just deleted my windows XP and installed Ubuntu 9.10 earlier this morning. I used wired connection to get drivers for my wireless network card.

When I did lspci, the very last line states:

Network Controller: Broadcom Coporation BCM4311 902.11b/g WLAN(rev 01)

I have a Dell Vostro 1700 with the Broadcom BCM4312 card (obviously). Running 10.04.

Earlier today the wireless was working fine, then after a reboot, it stopped.
