System76 Lemur Pro model lemur10 (newest) Wifi AX201 driver fails to load occassionally

Hardware: System76 Lemur Pro -- lemur10
Priority: Non Critical, work around found.

Wifi does not work 50% of the time. I am able to get it to work by executing

sudo rmmod iwlmvm iwlwifi
sudo modprobe iwlwifi

here is dmesg & inxi. Dmesg shows it failing, then me reloading the wifi driver to get it to work.

I have paid for pro ( can create ticket if necessary ).

Which one of them is WiFi?

done with wifi running.

There is not chipset name??
This will be a tough one :frowning:

This is helpful at least...

I am heading out the door to get supplies from the store; :smiley:

I hope you will be back...
I am not so sure if I can solve this by myself.

Oh, wait, it says this in the thread title:

Then I found this:

That thread gave me an idea.

Im going to attempt to use firmware from a later version of ubuntu / fedora and see if that works. I am not sure how linux knows which firmware to load. I will have to google it.

My God, that has got to be one of the worst message board sites I have ever seen in my life! As I am scrolling looking for the supposedly bloody solution, all I find are oodles of repeated posts saying the exact same thing.

As well as staff assuming far too much, and considering things solved, when there is no direct evidence leading to one to actually believe as such. There is a fine line between solved, and possible resolution. But their site layout leaves much to be desired. In other words, I think our site is much better!

According to what I could find, they suggested the possible solution as WPA2-PSK ' and Encryption 'AES. In other words, these have to be set in your Router's WIFI configuration. But doesn't normally everybody use WPA2 security protocal now days? However AES was important recommendation I guess.

Again, can't confirm any of this, you will have to do it on your end and see.

Ohh yeah, before I forget, I am....

I remember when I had Windows 2000 as a part of the network, I had to lower the security (WEP) for Win2000.
Since I have no idea about the local area network used by OP, it is still worth checking.

Intel seems to offer this for Linux users:

According to this page:
https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi

Intel® Wi-Fi 6 AX201
should be supported in kernel 5.2 and up.

So I am attempting to figure out how to instruct zorin to use that firmware. I have it copied over already to the other drive.

It is perhaps your system is too new for Zorin?
I am just guessing. But I've heard that the very recent hardware works better in Fedora as well as Arch based distros.

I hope @Aravisian will be back to this thread soon. He is way more knowledgeable than myself.

I would actually just leach it off PopOS;

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 63C46DF0140D738961429F4E204DD8AEC33A7AFF
sudo add-apt-repository "deb http://apt.pop-os.org/release $(lsb_release -cs) main"

sudo apt install linux-firmware

sudo add-apt-repository --remove "deb http://apt.pop-os.org/release $(lsb_release -cs) main"

I did not notice it in the title, either. :wink:

This is my first time to see that mighty command
lspci
does not give a name of the chipset.
I hope this is not the trend we are heading for.

There is a reason why I am running POP OS on my main gaming machine, its cause the computer is new, well, it was April of this year. You gotta have recent kernels to operate modern hardware. And for the record, Zorin OS 16 wasn't released yet, and I couldn't wait nearly half a year for its release to use my new machine, so it kind of forced my hand in the matter.

But turns out, I love POP OS on my gaming machine. But here's the thing though, I also love Zorin OS too, and couldn't be without it, so I got Zorin OS running on my Star Labs workstation, an older computer indeed, but Zorin OS runs good on it, even though its CORE AKA Gnome!

I tell you what though, once the Zorin brother's release LITE, you watch how many more installations start happening of Zorin OS because of LITE's release. People like Jeff and other's, they will have it installed so fast, they will make Varuca look bad lol.
