I have Lubuntu installed on my HP laptop, It does not show any wireless connections nor the options to turn it on. The WiFi light and activate button is dead.
When I run a LIVE install of other linux flavors like Debian, Peppermint, Mint, and Ubuntu, WiFi is always there and activated.
What am I missing in Lubuntu?
Why wont it pick it up?
Any help would be great.
Thanks.
I canāt see any reason for Lubuntu to be any different to Ubuntu itself as they both have the same Ubuntu base, assuming the releases are equivalent with same software stacks (ie. comparing HWE with HWE, and not HWE with non-HWE).
The same would apply with Peppermint & Mint which are based on Ubuntu, and Debian which is very similar (in my experience I have less hassle with getting devices to work on Ubuntu/Lubuntu when compared to debian); though again the age of the software stacks is the most significant difference. The software in this my primary Lubuntu 20.04 LTS system is newer than my Debian bullseye (testing/sid) box in nearly all cases; in some rather significantly.
Your comparisons only make sense if you gave software stack ages; which debian? which ā¦
If it were me, Iād boot a OS that works (āliveā system for example) look at what release, kernel, etc is being used - then sudo lshw -C network to see kernel module (driver) is being used (the ādriver=ā bit) then go back to where you want it (Lubuntu) see if itās there, if not install it; if where it works has HWE enabled, enable HWE on your wanted system.
Lubuntu 18.04.3 LTS installs will be using the HWE software stack inc. 5.0 kernel, however a Lubuntu 18.04 LTS (or 18.04.1) install will not have HWE enabled by default (4.15 kernel), even if full-upgraded to 18.04.3; thus will have slightly older ādriversā noticed on new devices.
What you are missing primarily as I read it is by ignoring release/version detail - the age of the software stack enclosed within. Even having a 18.04.3 updated system could represent to different ages of software stacks, because of the install media used which dictates if HWE is used or not (unless enabled post-install).
For info on HWE see Kernel/LTSEnablementStack - Ubuntu Wiki
Thank you Chris,
This all makes sense to me. I will do my homework and get back to you with the results.
Thanks again for you time.
Chris,
Here are the wireless network reports:
The first is Peppermint 10. it works!

Notice there is NO driverversion= ???
I followed you instructions and updated to 5.0 kernel.
Still NOTHING!
Not even the new kernel being there as follows:

BTW, Is there a way to turn on HWE or the wireless adapter? itÅ not present in Lubuntu.
I still donāt know if youāre using HWE on your Lubuntu system, did you install Lubuntu 18.04, 18.04.1 (no-HWE by default) or later (18.04.2, 18.04.3 with HWE enabled). Are you using the 4.15 kernel? or 5.0?
Does this differ to Peppermint (ie. is it using HWE? and your Lubuntu isnāt because of your install media used, or you havenāt enabled it. I donāt know Peppermint so have no idea if they default to HWE enabled or not).
The link I provided in the last comment includes the command to enable HWE for servers and desktops (use the desktop command for Lubuntu). I provided this because of your last line; at grub at boot time you can control if the non-HWE is used (4.15) or HWE kernel (5.0) is used
Iām assuming you rebooted, and booted into a 5.0 kernel. Have you tried using nm-tray (Network Manager) to connect to your wifi network? (https://manual.lubuntu.me/stable/3/3.1/3.1.5/nm-tray.html)
If you have but still problems, do you see anything with ip -d link (show ip (-detailed) link information). I suspect the driver=b43-pci-bridge difference is the issue; a dirty blacklist may fix but Iād hope there is a better solution. Iād want to learn more about b43 & pci-bridge to advise.
I donāt have time to explore currently, with luck very late today I might see if I have a device with b43 and can explore it.
Chris,
Yes I have the 5.0 kernel, Yes I rebooted. and, Yes I read all the documents you send and follow your complete instructions to the teeā¦
I installed Lubuntu from a .ISO from this site. (official right)???
Burned the image to a thumb drive, and took all default install options, did not change anything.
Here is what I get for nm-tray :
administrator@LUBUNTU:~$ nm-tray
Command ānm-trayā not found, but can be installed with:
sudo apt install nm-tray
administrator@LUBUNTU:~$ sudo apt install nm-tray
[sudo] password for administrator:
Reading package listsā¦ Done
Building dependency tree
Reading state informationā¦ Done
E: Unable to locate package nm-tray
administrator@LUBUNTU:~$
I GIVE UP!
It makes no sense to meā¦ (How do you turn something ON, If you can find it, OR install it?)
nm-tray is not a program you should be running from a terminal; I sure donāt (I just tried it on my box; 20.04, and it added a second ānm-trayā icon on my panel). I was possibly unclear, for which I apologize.
I did use program highlights yes; but I meant using the detail found in the Lubuntu manual - https://manual.lubuntu.me/stable/3/3.1/3.1.5/nm-tray.html where I hoped nm-tray icon was already visible on your panel.
I didnāt get to look info b43 / b43-pci-bridge yesterday or today. I did look for hardware that has that chipset, but I have nothing, nor have access to anything with that hardware where I hoped to test. Sorry currently I have nothing valuable to offer.
Possibly try installing this package
https://packages.ubuntu.com/bionic/firmware-b43-installer
sudo apt-get install firmware-b43-installer
Itās found in āmultiverseā, so youāll need multiverse enabled before itāll be found.

You did it Buddy!
ItÅ all there, and all works great! Thank you so much. And even on Thanksgiving. You ROCK!
