Comment 4 for bug 1980668

Thanks a lot Juerg and Dave for your answers and sorry for my late reply, I first had to reinstall Ubuntu 22.04 after finally having found how to install Ubuntu 21.10 to check whether it worked better or not. This took me some time and it appears that it does not work better with Ubuntu 21.10. I gave more explanations regarding this experiment and other things I noticed here: https://answers.launchpad.net/ubuntu/+question/702320

First, sorry for my misunderstanding of the boot logs regarding the firmware load error, I did not notice that despite this error message the right firmware is correctly loaded.

I tried to manually install the firmware files from GitHub as you suggested Juerg. I checked the firmware version in the boot logs and it is the expected one. This unfortunately did not improve the network stability.

I also tried to install the package update as you suggested Dave. I get the exactly same firmware version in the boot logs. As far as I understand, they are the same file, but you packaged them to make the install and uninstall easier, is this correct? The device is now running with this package, and it unfortunately did not change anything.

It remains me to check with the right Wi-Fi region. I was not able to do it for now. I hoped I could connect to the device just after the boot to set the region (sometimes it works for a few minutes), but that did not work. I am going to bring the device back to the house, connect to it and make the change persistent in order to get it directly boot with the right version. I'll let you know when I have tested that.

As I explained in my other post here https://answers.launchpad.net/ubuntu/+question/702320, I think there is a recent change in the device environment that causes some interference. That could explain why the connection is unstable and the throughput very low when the connection is working whereas it worked better a few months ago when I initially installed the device (the connection was stable, the throughput was not very high but clearly satisfying for my use case).

But there is something that remains quite strange and that makes me thing that there may be an hardware or a software issue, it's the fact that the device is generally able to connect at boot but only for a limited time (between a few seconds and multiple hours). After that period, it gets disconnected and is generally no longer able to connect again. What could explain that the connection is only possible after a fresh boot?

Thanks again for the time you spent on this issue and your answers!
