Reinstalling LL after losing wifi due to installing updates

[bobw]

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

[bobw]

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.

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

remove any of the packages you previously installed for that wifi
and install this

Code: [Select]

sudo apt-get install firmware-b43-installer

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

Lets see what  PCI ID you have for that wireless

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.

Network:   Card-1: Broadcom BCM4318 [AirForce One 54g] 802.11g Wireless LAN Controller driver: wl
           IF: N/A state: N/A mac: N/A

Given that new info, go ahead an follow instructions posted by bitsnpcs a few posts ago.  Boot into installed LL (not live CD) with ethernet cable plugged-in; then open a terminal and enter the four commands in order shown in his post.  When done, reboot computer without ethernet cable attached and hopefully your wifi will be working again.

P.s.  It's entirely possible that when you enter "sudo apt-get install linux-firmware-nonfree" command it will come back saying that it's already installed.  That's fine, just continue on to next steps.

Earlier, I gave the wifi card & driver information when I used the CD to access the internet. I removed the CD and hooked up the ethernet cable and looked at the wifi card & driver information again and came up with a different driver. Below is the new (correct) information when using the ethernet  cable to access the internet.

Network:   Card-1: Broadcom BCM4318 [AirForce One 54g] 802.11g Wireless LAN Controller driver: wl
           IF: N/A state: N/A mac: N/A
           Card-2: Realtek RTL-8100/8101L/8139 PCI Fast Ethernet Adapter driver: 8139too
           IF: eth0 state: unknown speed: 100 Mbps duplex: full mac: <filter>

Hello Rob,

yes indeed, an apt phrase

Hello!

Thanks. After all, why 'throw out the baby with the bath water'?

Hello AZ,

Source - 'Varun'

The sta driver won't support your card, the native b43 will. Please purge the sta driver package and install the firmware for b43 instead -

Code: [Select]

sudo apt-get purge bcmwl-kernel-source
sudo apt-get install linux-firmware-nonfree

Then unload (if already loaded) and reload the b43 driver-

Code: [Select]

sudo modprobe -rv b43
sudo modprobe -v b43
Remove ethernet cable.
Reboot machine.

Not really an expert on wifi problems, but let's see if we can fix this.

Edit:  If anyone else who is familiar with Broadcom problems wants to jump in, please do.

Go to Menu -> System -> Install/Remove Software to open up the Synaptic Package Manager.  Highlight "All" and "Status" on the left-hand side of Synaptic, then type "broadcom" in the "Quick filter" search box.  (If Quick filter not showing, just use "Search".  Once you do a first search in Synaptic, when you close and re-open the program it will then start showing the "Quick filter" box.)



Try to adjust size of results window so that all of the boxes shown in green show up without you having to scroll.  When you have that done, take a screenshot of the window and post it back here for us to see.  Menu -> Accessories -> Screenshot -> Active window -> OK -> Save -> then change name of screenshot to synaptic.png and save it.  (Use directions in this post for including screenshots in your reply:  https://www.linuxliteos.com/forums/index.php?topic=487.0.)

Also, go to Menu -> Settings -> Install Drivers.  After it finishes loading, take a screenshot of that and post it back here.  Don't change anything with the program -- just take the screenshot, then close the window.

Lastly, open a terminal and post back output from this command:

Code: [Select]

apt-cache policy linux-firmware-nonfree bcmwl-kernel-source

Hi gold_finger,

Here are the results from the last command, inxi -nz.


linux@linux:~$ inxi -nz
Network:   Card-1: Broadcom BCM4318 [AirForce One 54g] 802.11g Wireless LAN Controller driver: b43-pci-bridge
           IF: wlan0 state: up mac: <filter>
           Card-2: Realtek RTL-8100/8101L/8139 PCI Fast Ethernet Adapter driver: 8139too
           IF: eth0 state: down mac: <filter>
linux@linux:~$

Thanks,
AZ

I agree with N4RPS here.  Think you're better off trying to get wifi working vs. going through a new install again.  Have a feeling that as soon as you run updates after the install you'll just end up back where you are now.

Temporarily use an ethernet cable for now.  Open a terminal and enter following commands one at a time.

Code: [Select]

sudo apt-get update
sudo apt-get install inxi
inxi -nz
Copy/Paste back here the output of that last command which will show us what kind of network card is on the machine and what driver it's using.
