I’m a new user of Ubuntu MATE. Installed 16.04 LTS from de DVD, got my wifi working and have been happy and very content user since a couple of weeks. Then last week got the message that there were updates. followed instructions to install them and now my wifi isn’t working anymore. Cannot find the info to get it working again and would appreciate your help.
Read that I needed to do following command, but after that I’m lost.
Hi @Bill_MI thanks for your reply.
The 'rather old' Broadcam is because of my 'rather old' Dell Vostro 1510 that got a new life and works like new thanks to Ubuntu Mate.
The additional driver was already uploaded and worked (till 6 days ago before the upgrade)
I tried to change to "don't use" to be able to reload it afterwards, but doesn't work. I don't seem to be able to access it through the standard menus.
The usual sequence is to remove your old Broadcom wifi driver first and then to install a broadcom firmware installer (using an ethernet connection of course) and then reboot. This page has a complete explanation.
Thanks @mdooley for your answer. Went to the site and read that I should first undo previous installed drivers. Didn’t know how to do that, tried copying a guide from the forum, but got stuck half way. Rebooted my system, then tried it via the system>control center>updates & software
There I succeeded to undo the use of the broadcam pilot. Rebooted, via the same menu activated the broadcam pilot and Voilà… writing this message via Wifi connection.
thank you so much for your help and the link that got me unstuck
I’m reopening my question because Wifi connection isn’t working. During some time it worked perfect, than intermittent and now not anymore.
I installed last updates, didn’t solve the problem.
I tried via System -> Preferences -> Hardware -> Additional Drivers to change to “don’t use” to be able to reload it afterwards, but doesn’t work. Cannot undo the installation.
Since I’m really a newby in Linux, can you please tell me what code to use to de-install drivers via Terminal ? So that I can try to re-install afterwards.
Otherwise : can anyone suggest a USB wifi that works well ? Don’t need mega speed because I’m in the countryside and don’t have fast connection, just want it to work.
Thanks @mdooley for your answer.
All goes well until I get to "sudo apt-get install firmware-b43-installer"
It asks me to insert disc. Which I do, I press enter and there it buggs.
Maybe it's because it asks me to insert in the drive '/media/cdrom/'
and I think it's called '/media/esther/' ? Could that be the source of the bug ?

@Esther_HV In order to install firmware-b43-installer, you must have an ethernet connection. For me, that meant walking my laptop over to my router and connecting to the internet via an ethernet cable. Is that possible where you are?
Edit2: Sorry to be so forgetful. I looked on my DVD installation disc and found where you can get the b43-fwcutter .deb without a working internet connection. Hopefully this will help you get through this connectivity issue. Please see screenshot below.
Edit: Finding and using the B43-fwcutter deb was insufficient to get my Broadcom device working on an install of UM 17.10. I had to connect via an ethernet cable and run the commands in post #8 above.
Hi @mdooley,
Thank you for taking the time to reply to my newbe questions. Did programming, but all in DOS and Pascal when at universaty, but that is already 25 years ago. I' m kind of handy with computer compared to the average user, but with Ubuntu Mate (Linux) I'm beginner. Don't know the codes, have a hard time figuring out what extensions are programs, etc. So you help is really appreciated.
Yes I do have connection to the internet via cable. Am most of the time on my couch with laptop on knees, but hard for my back, so really want to get this wifi connection going again.
Think I can find the file you mentioned, where do you suggest I paste it.
How do I adapt the code you suggested me :
First do
sudo lshw -class network
then
lspci -vvnn | grep 14e4
to find out if there is a broadcom (BCM4311) controller. Then
Don't ask me why, but finally got it working again and via the menu
System -> Preferences -> Hardware -> Additional Drivers
This time only selected the drivers for the Broadcam and didn't activate the drivers for Processor and this worked.
Don't know for how long, but at least learned something again about Linux and commandes (looked up some commands on internet, so was useful for something).
Thanks again @mdooley for your help, was much appreciated.
Hello, reopening my question, because I still have a strange problem with WIFI connection.
In the office, WIFI works without any problems. Connects automatically.
At home, wifi doesn’t work. No way I can get it running.
So I want to buy a USB WIFI dongel and trying to figure out which one will work with Ubunt MATE 16.04.01.
Our livebox at home is a 802.11ac.
Anyone with advice on what material to buy that works without all kinds of adaptations ?
Thanks in advance.
