Reinstalling LL after losing wifi due to installing updates

[AZ]

I attached the ethernet cable, entered the four commands posted by bitsnpcs, removed the ethernet cable (hooked up the wifi) & rebooted and still had no wifi. I tried entering the four commands again and still no wifi. Any ideas. Thanks.

Lets see what  PCI ID you have for that wireless

Code:

lspci -nn -d 14e4:

Below are the results from the command: lspci -nn -d 14e4:,

gary@gary-Presario-V5000-RG324UA-ABA:~$ lspci -nn -d 14e4:
06:02.0 Network controller [0280]: Broadcom Corporation BCM4318 [AirForce One 54g] 802.11g Wireless LAN Controller [14e4:4318] (rev 02)

[14e4:4318] (rev 02)
remove any of the packages you previously installed for that wifi
and install this

Code:

sudo apt-get install firmware-b43-installer

Thank you very much misko_2083. I installed the code and I'm now able to get on the internet with a wireless connection.

I'm experiencing a similar problem today.  I already have 64-bit LL2.0 on a PC, and today I have installed the 32-bit version on an elderly Dell Inspiron 1525 laptop as a dual-boot with Windows Vista.  At first the wireless connection was working OK with the installed LL (I succeeded in synching my Google & LastPass accounts), then it stopped working.  The wireless connection still works in Windows and when I boot from the LL CD.

I've followed the instructions in Post #2 from gold_finger, and the results of the inxi -nz command, in the installed LL, are:
Network:  Card-1: Broadcom BCM4311 802.11a/b/g driver: wl
          IF: N/A state: N/A mac: N/A
          Card-2: Marvell 88E8040 PCI-E Fast Ethernet Controller driver: sky2
          IF: eth0 state: up speed: 100 Mbps duplex: full mac: <filter>

The command "lspci -nn -d 14e4:" suggested by misko_2083 returns no result.

I have also installed the firmware-b43-installer as per Misko_2083's Post #13, and rebooted without the ethernet cable, but the  wireless connection still doesn't work.

Incidentally, if I need to reinstall, could I use the 64-bit LL2.0?  There is a system report attached - it suggests that the CPU has 32-bit and 64-bit operating modes.

Regarding my final question, I've now established that it is a 32-bit machine.

Just some more info to read for you broadcom chip users.

https://help.ubuntu.com/community/WifiDo...er/bcm43xx

Since Linux-Lite 2.0 is based on Ubuntu 14.04

It explains that the wl driver is the proprietary broadcom driver and b43 is the open source driver.
Confusing I know. But that is broadcoms fault, (just my opinion).

For the b43 open source :

Note: Not all PCI-ID's and/or modes are supported.

So pcid with broadcom is a must. Seems like all broadcom chips are not created equal.
You should though just be able to get your 4311 working. Just some other colored hoops
broadcom wants you to jump through is all. And they do make it hard.

bobw,

Code:

sudo apt-get update

Download new pci id list

Code:

sudo update-pciids

try again

Code:

lspci -nn -d 14e4:

if it's
14e4:4311 
then you'll have to remove the existing drivers

Code:

sudo apt-get purge bcmwl-kernel-source firmware-b43-installer

And install linux-firmware-nonfree

Code:

sudo apt-get install linux-firmware-nonfree

reboot
Broadcom drivers are a mess

Thanks misko_2083.

Response to the 3rd command is:
0b:00.0 Network controller [0280]: Broadcom Corporation BCM4311 802.11a/b/g [14e4:4312] (rev 01)

So it's 14e4:4312, rather than 14e4:4311.  Should I now omit the 4th command and proceed to the 5th?
