Title: [SOLVED] Kubuntu not recognizing wlan0 on dell latitude laptop
Post by: Detroit_Bad_Boy on March 27, 2018, 06:59:51 PM
First I cannot read the tiny lettering that shows the exact latitude model
To the heart of the matter kubuntu will recognize wired connection but no wireless connection.
Any help would be appreciated

Well, you know about what model it is, right. Get on Dells site and determine every possible chipset they used in your family of laptop. Get the part #.

Then combine that model number(s) with words like firmware and ubuntu and googduckbing around awhile until you come up with the needed firmware deb.

Then load it.

I thought ubuntu had some fancy detection and software center that would do this for you, but the method stated is what I do with Debian and there's all the info out there you need. Tangents include how to install a deb, how to ask the system (lsusb, lsmod), what utility to use to control it all (wicd).

As I understand it some wifi thingies are still not supported.

What kind of wireless chipset is it?  You might want to check if the linux-firmware package is installed as it contains the firmware for a lot of different PCI hardware.

Here is what I want to achieve:
Since it would be an arduous task to get kubuntu to recognize the BCM3422 chipset in the laptop, I have shifted gears. 
I know that manjaro works VERY well with the laptop and gives instant wifi connection. The problem with that installation is that I have to use a flash drive for the install. I tried to create a UEFI flash drive with manjaro loaded on it, but all I have is Unetbootin and that does not have the UEFI capability. 
Is there a program that works with kubuntu that creates a true UEFI flash drive with the OS of my choice loaded on it?

 BCM3422
 This would do the trick?

Package: firmware-b43-installer (1:019-2) [contrib (http://www.debian.org/doc/debian-policy/ch-archive.html#s-contrib)]

I've had great success with ether, dd on the command line also tends to work without fail.

You may not need to be!
So you need a way to get the firmware file you need onto the computer that has no internet? Is this right? You don't have a copy of the firmware.deb needed on the computer or a CD or anything?
You are using your phone for access? Yes?
If so you need to download the deb I mentioned, or double check if ubuntu has it's own version. Get it onto the phone. From there, get it on the computer. From there figure out how to install it...
Or, take the laptop anywhere you can wire in! Fix it in the software center of ubuntu. maybe...

If the cell phone has WIFI tethering you could use that...

Of further interest, I use "FX file explorer pro" on android and it has WIFI hotspot which allows me to transfer files from my phone to my PC using the wireless network or my phone's tethering support... "Wifi file transfer pro" also lets you do the same thing...

Downloading content to the phone to transfer to the computer is always a nice option... my mobile doubles as a USB stick
Title: Re: Kubuntu not recognizing wlan0 on dell latitude laptop
Post by: CwF on March 28, 2018, 06:44:53 PM
...can't use the wifi! That's what is not working!? Bluetooth, usb, sdcard,...
haven't even got to installing a foreign deb yet...
I used on of those mtk chipset chinese spy-on-me military phones forever that had a cdrom mode, mount an iso from it's sdcard bootable or not and every computer tried could read it.
Anyway I'm hoping his ubuntu has gdebi preinstalled... I stopped paying attention to ubuntu's but unless you know what to do a fresh install needs to be from a non-free media. At least for debian, a bare install includes few firmwares.
I've been in this very trap.

That is quite odd considering I have had pretty good experience with DELL computers in the past. Broadcom has always been a major PITA where linux compatibility is concerned. The only distribution which will power my broadcom hardware out of the box is Manjaro when you boot the LIVE image in nonfree mode. <sigh>

Perhaps I didn't give the right explanation. Internet connection in lower right corner shows ethernet connection but gives nothing for wifi. I cannot even connect via hotspot on my phone. I suppose I will have to wait for my own internet service to be set up so I can hard wire the laptop and then install the chipset driver
Title: Re: Kubuntu not recognizing wlan0 on dell latitude laptop
Post by: CwF on March 29, 2018, 12:05:28 PM
I think you did describe it right. Think of the this is parts. The indicator you mention is likely "network manager", or ONE part. It shows the wired network on behalf of another part, the driver package for your wired hardware. A third part would be the driver package for your wifi chip. That is what is missing.

Go here: https://help.ubuntu.com/community/WifiDocs/Driver/bcm43xx
maybe here too: https://askubuntu.com/questions/730799/installing-firmware-b43-installer-offline
Once you got that covered, let us know.You may get snagged trying to get the deb installed. Next you may want to use wicd instead of network manager and either may need some configuration. This is fixable!

When I was running Linux Lite (ubuntu) on this notebook I had the same issue and I needed to have a wired connection to fix the problem. The links supplied by CwF should get your started but if memory serves I remember having to install a PPA to get the correct firmware installed. Since I do not know which version of Kubuntu you are running I cannot direct you to the correct commands to add this PPA but you can find the launchpad for broadcom HERE  (https://launchpad.net/ubuntu/+source/broadcom-sta)and that should have up to date drivers for you.

You know, the ONE thing I make sure to check anymore when selecting a linux laptop is wireless, Broadcom is a dealbreaker.

When I run the command lspci -vvnn | grep -A 9 Network it shows that I have the bcm43228 chipset. It also shows kernel driver in use: bcma-pci-bridge. I wonder if this is showing a driver is in place.
Also, I can go in to network manager and create a wi-fi connection. When I copy in all the necessary info it does nothing and does not connect

can you connect the phone to the laptop via a USB cable?

Download the packages you need to the phone, transfer to the laptop via USB, install, problem solved.

I downloaded the cutter and the driver. The driver will not install due to a dependency issue. The cutter cannot install as Konsole does not find it. I have no clue to tell it where to look.
What am I missing here?

You may have to search the Ubuntu forums and try EACH method they suggest to get the broadcom wifi working... I remember having to go through a list of suggestions until I finally got it... Persistence is key. There is a solution but I had to work to find it! Because I no longer use Ubuntu based systems I did not save my notes on what I did to get it operational.

<LIGHTBULB>
Have you considered trying the NDISWRAPPER (http://www.stchman.com/install_ndis_broadcom.html)? It comes bundled with many of the Buntu distros and it will let you use a WINDOWS driver to get that wifi interface working.... there are plenty of tutorials explaining how to use ndiswrapper... so why not give that a try???

double check, type " lspci -d 14e4: " in a terminal and see if there is any feedback. None = wrong package, if there is feedback it will be details for you broadcom... hopefully. If so, next step is configuring whatever

It shows Broadcom BCM43228. Apparently it may have gone right

YAH! I left out if you add a -v to the command it should show the driver in use. From here we are outside my knowledge in KDE and Ubuntu. But as I bail out, the step may be as I expected; whatever networking is in use may need to be told what to do, what to use. Somewhere you will need to add the name of the device to use with/as wifi. The name to fill in will may be something like "wlx#######. where the ### is the mac address without any dividers (:). So try and determine what needs the info, the name of the wifi device as determined by your distro, and what that name is. I use wicd for all my machines since it's simple and leaves all but the first eth port alone and has an obvious wifi config area to type in the name of the device. I think you are almost there!

I'm not saying that broadcom cards cannot or will not work, I'm just saying that generally they've caused enough headaches that it's easier to get something that DOES work effortlessly like an Atheros chip.   If you're re-purposing a machine that you already owned, this isn't really an option, but if you're buying new just avoid Broadcom and save yourself the hassle.  I have 2 laptops that work effortlessly, one has intel wireless and the other has Atheros wireless, the only thing I've ever had to do is make sure the firmware package gets installed and they just work, and with *buntus the firmware generally seems to have been automatically installed with the system.

I'm in his position also, relying on a 4G hotspot. Having a long history of never being in one place it was a waste to pay for any more permanent solution. To avoid the entire subject I converted an ancient W54G router to be the hotspot receiver and then have real wired ports for zero config on any computer. Slow maybe, but fast enough for typical 4G. I bought a strange little usb wifi that looks like a little baby router with two external antennas and used it a few times in my truck. Often in my areas satellite or p2p microwave was the only type of internet and even 4G was out of range. Anyway, I adopted many usb dongles along the way, people just give me stuff. So moving into linux I had those wired ports on the old router to fall back on. So when I finally tackled the issue on vacation, yes, geek homework on vacation, I used a bare debian machine and started testing. After all the frustration demonstrated here I got them all working. Compared with phones, laptops, tablets, etc, the results all were similar with 5-7 signals seen and similar speeds. Then I remembered that chinese mini router thing which turned out to be a RALINK something. When I got it working it blew me away, showing a good 20+ signals! More than any device we all had. Back at home I confirmed it out receives even the modded full size router I'm using. Anyway, point is they all worked. One thing I've learned with linux is there is often not one way to do things and that makes it all very confusing. And "automagically" is not a linux talent. We don't know if he's out of the water yet....

I'll keep working on the issue. Once I get a hardwired connection I should be able to resolve it faster than DL'ing stuff, put it on a flash drive, then running to the laptop to try it out. Thanx for everyone's input on this issue. It is much appreciated.

Too bad you were unable to get a solve for Kubuntu but at least the Manjaro disk worked for you. For now I will mark this topic as solved and if you have further problems, feel free to start a new topic.
