Ubuntu 11.10 no wireless

Hi, that happens a lot during a power loss, it may not even have anything to do with the commands you were running at the time, power loss causes file corruption and bad sectors on the hard drive.

Thank you praseodym.

Hi, it looks like you installed the driver for this card in additional drivers if so please do this:

sudo apt-get purge bcmwl-kernel-source broadcom-sta-common broadcom-sta-source

Then run this command and watch for errors.

sudo apt-get install b43-fwcutter firmware-b43-installer

After it intalls disconnect your wired connection and restart your computer.

I may not be the original poster too, but this fix my situation as well. i've been working on it for days trying everything i found in this forum and this simple two things fix my thing.

Hi everyone,
I [like a few people here] recently downloaded/installed ubuntu 10.11 and since I am having a few problems with my wireless connection.
I was hoping someone here mght be able help me or point me into the right direction to resolve this issue. I've attached a notepad with my results from the following commands:

sudo lshw -C network

lspci -nnk | grep -iA2 net

iwconfig

rfkill list all

lsmod

sudo cat /var/log/syslog | grep -e b43 -e wl -e firmware -e wlan0 | tail -n35

sudo apt-get purge bcmwl-kernel-source broadcom-sta-common broadcom-sta-source

Then run this command and watch for errors.

sudo apt-get install b43-fwcutter firmware-b43-installer

After it intalls disconnect your wired connection and restart your computer.

I have also downloaded the zip file [on page 2 of this thread] which consisted on the b43 file. I carried out the commands attached, but again no luck.
I've tried rebooting many times
Any help would be greatly appricated.
thanks,
thegant

Hi thegant,

the module "wl" from the STA driver is still loaded:

sudo modprobe -rfv wl
sudo modprobe -v b43

Check:

iwconfig
dmesg | grep b43
sudo iwlist scan
rfkill list
iwlist chan

Is it a Dell laptop?

[wildmanne39]

Hi, did you have a connection to the internet when you ran the purge command and the install command?

This should get you going but you will need to be hard wired to the internet first.

sudo apt-get purge bcmwl-kernel-source broadcom-sta-common broadcom-sta-source

sudo apt-get purge firmware-b43-lpphy-installer

sudo apt-get install b43-fwcutter firmware-b43-installer

Reboot and it should be working.
thank you

Hi praseodym,
thanks a million - it is a Dell laptop and the commands you supplied above worked!
Can't believe it - thanks for you quick reply and help.

Hi wildmanne39,
thanks for your quick reply also. You were right, I wasnt connected to the internet. But the command that praseodym supplied worked before I got to yours.
Thanks a million - youre both very good to help.
Best regards,

i use the method above, and that resolve my issue, but some update from above.
the package "firmware-b43-installer " changed to "firmware-b43-lpphy-installer", the "lpphy" is low power.
thanks again.

computer setting [Dell inspiron, broadcom 4312 wireless], for reference.

Hi, I am glad you got it working!
Enjoy

My HP dv9000 worked with the b43 driver and not the bcmwl driver. I have a Broadcom BCM4311 [14e4:4311].

Had to make sure I uninstalled the bcmwl driver for the wireless card to work.

Thanks
