Hi, my wifi board with trisquel 9 does not work in live mode nor installed on disk. I remember that in trisquel 6 and 7 it worked fine. In debian 9 it also works without problems, but I just installed trisquel 9 and it doesn't work. The same happens if I install debian 10, it doesn't work either. Here are the sources I have consulted:

I have already changed the grub configuration as shown in the image and updated with sudo update-grup but it does not work.

I have been dealing with this problem for the past year and I still can't find a solution. All modern distros, debian 10, xubuntu 20, Linux mint, trisquel 9 all have problems, except debian 9 and older versions of trisquel and ubuntu.

I hope you can help me. Regards

I just added only acpi=off in the GRUB_CMDLINE_LINUX_DEFAULT line and it works. Attached is my new configuration, everything working...

GRUB_DEFAULT=0
GRUB_TIMEOUT_STYLE=hidden
GRUB_TIMEOUT=0
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=off"
GRUB_CMDLINE_LINUX=""

Greetings and thanks again to all...

now my question is, in live mode, is there any way to put acpi=off and do update-grub. Would it work in live mode?

When I set acpi=off my wifi works, but 3 cores of my cpu (intel i5) are disabled. I attach 2 images, the one with the 4 cpu's is without the acpi setting.

This in the end is not an ideal solution, I solve the network but I take resources away from my pc.

I am waiting for another better solution.

well i haven't had a similar problem, but things i'd try perhaps is acpi_osi with a version of windows that would be more for your computer?

Be careful with grub wrong options might make it unbootable
changing lines to

GRUB_TIMEOUT="5"
GRUB_TIMEOUT_STYLE="menu"

would make it so you could try out stuff more easier, by hitting e at the grub menu and trying out kernel boot paramaters

"Examples

Windows 7 – acpi_osi='Windows 2009'

Windows 10 ver. 1709 – acpi_osi='Windows 2017'

You will notice that Windows 10 version 1709 has an OSI String of Windows 2017.2 and I used Windows 2017 instead. In my testing, I found that Windows 2017.2 was not recognized as a valid argument."

-https://endeavouros.com/docs/hardware-and-network/powersaving/acpi-kernel-parameters/

also perhaps digging around with some sysctl commands i might try.

good luck!

On Debian 9 installed everything works fine, why doesn't it work on trisquel 9 or debian 10?

My debian 9 configuration is as follows.
Grub:

GRUB_DEFAULT=0
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet"
GRUB_CMDLINE_LINUX=""

I can see that it varies the trisquel grub configuration as it adds splash I don't know if that could be part of the problem or not.

The system I am using with wifi without problems is:

Linux debian 4.9.0-15-amd64 #1 SMP Debian 4.9.258-1 (2021-03-08) x86_64 GNU/Linux

And I don't use Windows, only gnu linux distributions.
Maybe changing the kernel to the same one I am using at the moment could solve the problem, how do I change it?
Any other ideas to solve my wifi board problem?

You can download http://security.debian.org/debian-security/pool/updates/main/l/linux/linux-image-4.9.0-15-amd64_4.9.258-1_amd64.deb and double click on it. GDebi should propose its installation. You would then have to reboot and choose that kernel in GRUB's menu.

That said, it is risky solution, to say the least: the main Debian security team stopped supporting that kernel on June 18th last year (Stretch's end of security support).

perhaps try out "acpi=ht"

" acpi=ht

Deactivates the ACPI system almost completely; only the components required for hyper threading will be used. "

Hi, I have tried but it doesn't work. The truth is that I have no idea what could be happening.

Hello everybody,
i have a problem with an Atheros wifi adapter, maybe it has the same root.
I have been using this USB adapter for years without any problem, on Trisquel mini 7 and 8, but since several months ago the computer freezes within a second after i plug in the adapter and i can't do anything except pushing the power button.
On another computer with Debian 10 the problem was only that the adapter was not working. It now works perfectly with the 5.9 kernel. It doesn't work with kernel 5.10 though.
This is an Atheros ath9k chipset. The firmware for it is there, in Trisquel 8.
Any hints? Do i need a new kernel? Or simply upgrade to Trisquel 9 (If that is simple, at all...)?

The support for Trisquel 8 will end next month: you should upgrade anyway! See https://trisquel.info/forum/how-upgrade-trisquel-8-trisquel-9

If you use PPAs, executing ppa-purge (in Trisquel's repository) before the upgrade may avoid some problems.

Hi, sorry for the delay.
I was testing Debian 10 live. I have found that now when I connect an external ssd disk from a USB reader when I boot the PC, I can see the wireless networks and I can connect. But if I start Debian 10 live without the external ssd disk connected to the pc, I can't see the list of networks and I can't connect.

On the other hand, after installing Debian on the disk, I attach an image of what happens. I can't connect and I can't lift the network board either. When I write:
sudo ip set link up wlp2s0

It tells me something related to rfkill.

But well, now I want to understand why connecting an external USB disk in Debian 10 live recognizes the Qualcomm Atheros AR9287 Wireless board and without the disk does not.

Thanks

Hi, as I was researching, I think trisquel 9 has the same problem as Debian 10. I am not allowed to enable the wifi board by Fn+F3 switch. However in Debian 9 or trisquel 8 they work. See http://forums.debian.net/viewtopic.php?f=17&t=147269&p=735863#p735807

Hi, I just downloaded debian 10.09 netinstall. https://cdimage.debian.org/debian-cd/current/amd64/iso-cd/debian-10.9.0-amd64-netinst.iso

When I perform the installation the wifi network board is recognized and connects without problems to the wifi network. But when I finish the installation and boot the system with kde interface, the wifi board does not connect.

I can't understand what is the source of the problem. Please report this problem to be solved.

Regards
