Ubuntu 10.04 64 bit cannot connect to internet (b43 related problem)

http://askubuntu.com – I recently came upon a Dell 1545 Inspiron laptop and decided to put a fresh install of Ubuntu 10.04 LTS. At first I couldn't connect to the internet because I did not install the driver for my wireless card (broadcom 4312), but then I installed the first of the two drivers under the proprietary drivers list, it was the Broadcom b43 wireless driver. While that was active, I could detect wireless networks but could not connect to a network. I then tried to switch to the other set of drivers, the STA set. Now, I cannot even detect networks! Please help, and thank you for your time (HowTos)

Stories similar to Ubuntu 10.04 64 bit cannot connect to internet (b43 related problem)

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've recently installed Lucid Lynx 10.04 on my Dell Studio which uses an internal BCM4315 wi-fi card to connect to the internet. I was hoping it would work upon the install, but deep down I knew I'd have to tweak it a little bit to get it up and running the way I wanted.

The card was instantly recognized but, at first, wasn't detecting wireless networks.

It seems a lot of people are having this problem, but none of the posted solutions have worked for me so far. My driver is installed and activated, I have tried removing and re-adding the network, and various other fixes.

Hi All,

I am new to linux/Ubuntu and need some help!

I have a new Dell Precision M6400 core I7 laptop. i am not able to connect to wireless network.

i tried all options in the config guide but still was not successful. In the additional Drivers window i see that it is using Broadcom STA wireless driver.

I had 9.04 on my HP Pavilion DV6570, everything worked fine until I decided to install 9.10. I installed a fresh setup and now I can't use my broadcom wireless, when I go to Hardware drivers to enable proprietary drivers there is nothing to activate, no wireless driver, no graphic driver!

I recently installed Ubuntu 10.4 on my new Dell Studio 1558. After installing the broadcom proprietary driver for my wireless card, the wireless for my laptop worked fine.

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.

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%.
