[SOLVED] Ubuntu 18.04.1 LTS WiFi Stopped Working

GameDevGuy · 10-04-2018, 02:04 PM

Yup, it's another one of those pesky Wifi threads!
I am running a Gigabyte H370N WIFI with Intel CNVi 802.11ac Dual Band 9560 Wave2 2T2R (external split-tail antenna) WiFi.
Fortunately, I can pinpoint what I was doing when the WiFi became disabled. I had compiled the source code for Unreal Engine 4. I ran the editor, which worked fine. Then, I saved, closed, and reopened the editor. That's when I lost the WiFi. When I went to launch a test application window, the editor informed me that there was no network connection. I tried to log out to see if logging back in would fix the problem, but the OS crashed on logout. I rebooted and found that I still have no WiFi. I have done the appropriate terminal probing. Here are the results:

Hi & Welcome to LQ.

Try booting to an older kernel and see if that works. If that fails try the driver.
See the link below.

https://ubuntuforums.org/showthread.php?t=2329461

I don't see how installing Unreal Engine 4 wrecked the wifi:-)

The kernel driver is in use and so is the kernel module: iwlwifi

Here is the Linux Driver from Intel:
https://www.intel.com/content/www/us...etworking.html

Do you know GameDevGuy does Unreal Engine 4 have a configuration setting for wifi?

Ztcoracat · 10-06-2018, 10:20 PM

This info. could help others that could chime in and help.

Unreal Engine 4 comes with tools for game developers to design and build games, simulation and visualizations.
https://en.wikipedia.org/wiki/Unreal_Engine

In the meantime I've been going through this search to try to find the answer to solve the wifi issue. This search is based on the output from modprobe wl because the 'wl mod was not found' and thought it was a good place to start. Here's my search.

https://www.google.com/search?q=Modu...nt=firefox-b-1

I've also googled "unreal engine 4 stopped wifi" to see if that returns anything helpful. I'm trying but not getting to far.

******----------------------------------******---------------------------******--------------------------------******-----
***Anyone know how it is that the kernel driver is in use but the wl module is missing or not found?

GameDevGuy · 10-06-2018, 11:27 PM

I don't know that UE4 is the source of the problem. I don't think there is any WiFi config in that. There is a swarm feature that allows build processing to be done by multiple computers on a network. I will check and see what firmware is in the folder and I can download the one on the Intel website. I don't suppose the Bluetooth being in the kill list is connected to the issue. I did order a USB WiFi adapter that is guaranteed to work with 18.04. I figure that might allow me to bypass the issue, since it should use a different driver. Thanks for looking into it.

Ok:-

That's good that you ordered a wifi adapter just in case this issue doesn't get solved.

I'm not sure if installing that driver will help but you can certainly try it.
Once installed reboot and see. If not you can always remove the driver.

Let me know if rolling back to an older works or not:-

You're Welcome-
Always glad to help where I can.

GameDevGuy · 10-06-2018, 11:57 PM

I booted into the previous kernel. That didn't work. I downloaded the correct Intel driver. When I went to check the firmware folder, I found the exact same file already in there. I think I'll try to remove and reinsert the driver and reboot. UPDATE: The latter didn't work.

I had hoped that booting into a previous kernel would of helped.
Now I'm really stumped:-

I'm not sure if this is what you have going on or not. However it could (notice I said 'could') be that the kernel is too new and the driver is too old:- Something to think about.

Another thought-
Look in the dmesg log and see if the last handful entries are complaining about the wifi card.

Here's a troubleshooting Guide from Ubuntu for Wireless.
https://help.ubuntu.com/community/Wi...otingProcedure

Is your Ubuntu system on a desktop or a laptop?
If a laptop is it a Mac?

GameDevGuy · 10-07-2018, 12:48 AM

The system is a desktop I just built. It is PC components. I'm using the Gigabyte H370N WIFI Mini ITX. I don't think it's an issue of kernel versus driver. I tried two versions of the kernel. In the firmware folder, there are actually driver versions that are newer that aren't even listed on the Intel site. They are just sitting in the folder but not being used. I found some really interesting information. Here are the results of more probing:

Code:

nm-applet &
Gtk-WARNING Can't set a parent on widget which has a parent

This made it so I could see the WiFi icon. The drop down menu showed the two ethernet connections were disabled and did not list the WiFi. I was able to look at the most recent connection, which is what I was on before it stopped working.

that looks relevant.
if i'm interpreting it correctly, there's something wrong with the firmware.
not sure why it says "microcode" though.
please show us

Code:

dpkg -l '*firmware*' '*microcode*' '*ucode*'

GameDevGuy · 10-07-2018, 08:06 AM

Here is what I got. I'm not sure how to reconfigure the command:

Code:

dpkg -1 '*firmware*' '*microcode*' '*ucode*'
dpkg: error: unknown option -1

Type dpkg --help for help about installing and deinstalling packages[*];
Use 'apt' or 'aptitude' for user-friendly package management;
Type dpkg -Dhelp for a list of dpkg debug flag values;
Type dpkg --force-help for a list of forcing options;
Type dpkg-deb --help for help about manipulating *.deb files;

Options marked[*] produce a lot of output - pipe it through 'less' or 'more' !

dpkg -Dhelp
dpkg debugging option, --debug=<octal> or -D<octal>:

Debugging options can be mixed using bitwise-or.
Note that the meanings and values are subject to change.

According to Intel, if you see a message similar to the following, the firmware has probably crashed:

Code:

iwlwifi 0000:01:00.0: Microcode SW error detected.  Restarting

I have some additional information:

Code:

dmesg | grep 'microcode'

it's dpkg -l, that's a small letter L, not a number one!

Oops! Thanks!

Looks like others are having the same issue with the firmware crashing:-

The workaround is at the bottom of this thread. HTH

I don't feel like these are great solutions. The first one may or may not work, as far as that final post. Having to restart it every day would bug me. It should just work. On the second thread, they're just trying a bunch of "random" firmwares and hoping something sticks. That's ridiculous. Also, they are dealing with totally different hardware and firmware than I am. I'll resume work on this, tomorrow. I'll try the first solution. I mean the second idea about stopping the "correct" firmware from loading might work, but I don't know if the older or newer Intel firmware in the folder will work for my hardware. I'm definitely using the one that is recommended by Intel. Additionally, I am getting my USB WiFi adapter, tomorrow, that I ordered. I'll see if that works. I'll update this thread as soon as I get more info. Thanks.

it's too bad the "Name" field is cut short.
i think the firmware required by your intel wireless should be in some sort of firmware-nonfree package - maybe the "firmware-misc-..." is the one you need to install?
