Thanks misko_2083 - you're a star.

It's now working perfectly - ethernet cable is disconnected!

OK - done that.

Should I now follow the instructions at #26, or are some now redundant?

Thanks misko_2083 - you're certainly putting some work in for me.

I didn't get past the first command.  It returned message:
modprobe: FATAL: Module wl is in use.

What should I do now?

Try one more thing.
Maybe you card is supported by more than one driver, and they are conflicting.
First unload all the drivers.
Code: [Select]
sudo modprobe -r b43 wl brcmsmacThen loasd this driver:
Code: [Select]
sudo modprobe b43Wait a few seconds  and try to make a connection. If that works you'll have to blacklist the other drivers.
If that doesn't work  unload this driver and try this one.
Code: [Select]
sudo modprobe brcmsmacUnload, then try next driver.
Code: [Select]
sudo modprobe wl
Here is how to blacklist a driver
Code: [Select]
echo "blacklist drivername" | sudo tee -a /etc/modprobe.d/blacklist-broadcom-wireless.confReplace "drivername"  with the ones you don't want to use
You will have to do it twice because you need 2 lines in the /etc/modprobe.d/blacklist-broadcom-wireless.conf
One for each blacklisted driver.
Example:
Code: [Select]
echo "blacklist wl" | sudo tee -a /etc/modprobe.d/blacklist-broadcom-wireless.conf
Code: [Select]
echo "blacklist brcmsmac" | sudo tee -a /etc/modprobe.d/blacklist-broadcom-wireless.confUpdate the initramfs after any changes to the blacklist files:
Code: [Select]
sudo update-initramfs -uReboot:
Code: [Select]
sudo reboot

I don't think it was.  I made the disk about 3 months ago, before misko_2083 developed the Thunar facility for checking the MD5sum.  I've used to install LL successfully on two other machines, but they didn't have wireless connectivity.  I don't have the ISO file now.

If no other suggestions emerge, I'll try reinstalling from the present disk then if that fails I'll try a fresh download.

Usually when I see this part of a thread coming up ("it did not work also"). My next question is was a md5sum done of downloaded Linux-Lite iso.

Thanks again misko_2083 for all your help, and rokyntji for your response, but unfortunately it still hasn't worked.

I am wondering now whether I should try a reinstall - it's strange that the wireless connection was working initially then failed.

Any further suggestions would be appreciated though.

Unfortunately, that hasn't worked.  I also tried going back to the 4th command, then the 5th again, but still no success.

The output from the inxi -nz command is now:
Network:   Card-1: Broadcom BCM4311 802.11a/b/g driver: b43-pci-bridge
           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>

I've looked at the page suggested by rokyntji:
https://help.ubuntu.com/community/WifiDocs/Driver/bcm43xx

Should I try something from this page:
sudo apt-get --reinstall install bcmwl-kernel-source

This is for Ubuntu 12.04-12.10, so may not be right for LL2.0?

Yes, it's the same driver for 14e4:4312.

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?

bobw,
Code: [Select]
sudo apt-get updateDownload new pci id list
Code: [Select]
sudo update-pciidstry again
Code: [Select]
lspci -nn -d 14e4:if it's
14e4:4311 
then you'll have to remove the existing drivers
Code: [Select]
sudo apt-get purge bcmwl-kernel-source firmware-b43-installerAnd install linux-firmware-nonfree
Code: [Select]
sudo apt-get install linux-firmware-nonfreereboot
Broadcom drivers are a mess :)

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

https://help.ubuntu.com/community/WifiDocs/Driver/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 :

Quote
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.
