It looks like it's not actually loading the firmware in the 2nd one, it says it's already loaded. I wonder if you can force it to reload the firmware each time?

I'm confused by your question. I'm just an average user and I only have a general idea of how the operating system works. About the firmware.. If I understand correctly, updating / downloading firmware is a rather rare process. And once downloaded, the firmware will not disappear anywhere.
In any case, thank you for participating in solving my problem.

Hi!
Some idea please about my issue.
Looks like my problem too rare, and I have very little chance of solving it (((

Something very odd in that firmware saying that it IS already loaded. I am going to suggest to update your linux-firmware to the very latest. There are a number of things that have been updated since your version

Code: Select all

firmware-iwlwifi:
  Installed: 20230210-5

and the latest linux-firmware shows updates to that package as late as 20250311 !

You can update your linux firmware as follows:

Save a copy of your current /lib/firmware/ just in case... and personally, I would do a timeshift before proceeding.

Code: Select all

cp -r /lib/firmware ~/Backup

and then update is with this:

Code: Select all

wget https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/snapshot/linux-firmware-20250311.tar.gz ; tar -xf linux-firmware-20250311.tar.gz ; cd linux-firmware-20250311 ; sudo cp -R * /lib/firmware/ ; sudo update-initramfs -uk all

verify no issues / error messages and then I would shut all the way down. ( ie power off ). Wait 30 seconds and then power back up and test.

There also appears to be a number of posts about this model having issues with "disappearing bluetooth". Some are resolved with different drivers (windows), some with bios updates.

If the above firmware update doesnt help this situation... and a bios update also does not resolve it.. you may find the best solution is to pickup that bluetooth adapter I linked back a few posts ;-/

You don't seem to be sure about the advice you're giving. Cause:

Code: Select all

wget https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/snapshot/linux-firmware-20250311.tar.gz ; tar -xf linux-firmware-20250311.tar.gz ; cd linux-firmware-20250311 ; sudo cp -R * /lib/firmware/ ; sudo update-initramfs -uk all

This 1 liner looks very familiar from someone else. Even the -uk all part at the end is as is .


P.S. Don't worry, it'll work, no need to backup. However if you do not apt-mark hold "all" the firmware packages they'll revert back to older (than 20250311) when there are "updates".

Lose the attitude.

[CharlesV]

@Tom Dooley I try to let everyone know that backing up your system before you do a major tweak is a no brainer. Things can (and do sometimes) go wrong.

In my opinion... NOT telling someone to backup first is an issue and VERY poor tech.

And if you have a problem with that.. .you are free to leave the forum. ( AND yes.. loose the attitude please .. there is no reason for it.)

[Tom Dooley]

In almost all forums they tell you either to use your own words or "quote", otherwise you'll get banned just for this reason.

So, is this all you can say? "lose blah blah" or "eave the forum" as "moderato"rs ?

I hope you also read the P.S. part.

Banned.

@andre, please disregard TD's posts. Sorry for the distraction.
