SecureBoot disabled

Above are the information about our system.
I installed LMDE 6 on my Acer Aspire 5 A515-51G-54AW laptop with UEFI and secure boot disabled.
While installing the wifi detected my home router and I so I was connected during install.
Post install post reboot, I could still connect to my home router and downloaded many things and updating the drivers was one of the things I did.
Since next morning the wifi is detecting whole building's routers except my home router. I even tried to switch on my mobile hotspot and that as well not getting detected.

I saw that the network card i have is Qualcomm Atheros QCA9377 and so I did tha following:-

Code: Select all

sudo apt-cache search qualcomm

I got this:-

Code: Select all

libhalide14-0 - fast, portable computation on images and tensors
libqmi-glib5 - Support library to use the Qualcomm MSM Interface (QMI) protocol
gir1.2-qrtr-1.0 - GObject introspection data for libqrtr-glib
libqrtr-glib-dev - Development files for libqrtr-glib
libqrtr-glib-doc - API documentation for libqrtr-glib
libqrtr-glib0 - Support library to use the QRTR protocol
firmware-ath9k-htc - firmware for AR7010 and AR9271 USB wireless adapters
protection-domain-mapper - Qualcomm Protection Domain mapper service
qcom-phone-utils - Utilities for Qualcomm-based phones running Linux
qdl - tool to flash images to Qualcomm processors
libqrtr-dev - Userspace reference for QRTR -- development files
libqrtr1 - Userspace reference for QRTR -- shared libraries
qrtr-tools - Userspace reference for QRTR -- tools and services
rmtfs - Qualcomm Remote Filesystem Service implementation
skales - Boot image creation tools for qualcomm boards
tqftpserv - TFTP server implementation for the QRTR protocol
gobi-loader - Firmware loader for Qualcomm Gobi USB chipsets.
firmware-atheros - Binary firmware for Qualcomm Atheros wireless cards
firmware-qcom-media - Binary firmware for Qualcomm graphics/video (dummy package)
firmware-qcom-soc - Binary firmware for Qualcomm SoCs

Then I did

Code: Select all

sudo apt install firmware-atheros

And it said its already installed with latest version.
I tried removing it and installing again and rebooting, but it did not solve the problem.

Then I decided to upgrade linux kernel using backport so I did and got the latest version installed by the following command

Code: Select all

sudo apt install -t bookworm-backports linux-image-amd64

I rebooted and this time I was praying for the problem to get resolved, but sadly it did not.
I read every post about wifi not working on LMDE 6 available here and nothing seems to help.
I DONT WANT TO GO BACK TO WINDOWS.

Please help, any help will be hugely appreciated.

What result from terminal for

Code: Select all

dmesg | grep ath

[jwiz]

Probably went to sleep and didn't wake up again.
Try 'sudo modprobe -r ath10k_pc i&& sudo modprobe ath10k_pci'

[jacky-kumar-shaw]

Thanks a lot JeremyB for replying. I am glad. I am feeling now that my issue will get solved I will not have to go back to windows.

What result from terminal for

Code: Select all

dmesg | grep ath

The response for the above command is:-

Probably went to sleep and didn't wake up again.
Try 'sudo modprobe -r ath10k_pc i&& sudo modprobe ath10k_pci'

Tried this.
Did not help.

[JeremyB]

What country are you in?

[jacky-kumar-shaw]

What country are you in?

Sir, I am from India.
City: Kolkata
State: West Bengal

If its OK with you can we connect via call or something less asynchronous?

Also, I have been reading other answers by you regarding the same topic.
I did this:-

Code: Select all

sudo sed -i 's/wifi.powersave = 3/wifi.powersave = 2/' /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf

Now when I do this

Code: Select all

sudo nano /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf

I get to see this(even after reboot):-

Code: Select all

[connection]
wifi.powersave = 2

and then rebooted my system.
It did not help.

[karlchen]

Try 'sudo modprobe -r ath10k_pc i&& sudo modprobe ath10k_pci'

Tried this. Did not help.

Could not work because there is a typo in the commandline.
Corrected commandline reads: sudo modprobe -r ath10k_pci && sudo modprobe ath10k_pci
No warranty given that the corrected commandline will achieve the intended goal.

I knew there was an error and when I tried I tried in correct way. It did not solve the issue. Thanks for helping, it means a lot.

Code: Select all

echo "options cfg80211 ieee80211_regdom=IN"|sudo tee /etc/modprobe.d/cfg80211.conf
sudo iwconfig wlp3s0 power off

Reboot

[jacky-kumar-shaw]

Code: Select all

echo "options cfg80211 ieee80211_regdom=IN"|sudo tee /etc/modprobe.d/cfg80211.conf
sudo iwconfig wlp3s0 power off

Reboot

Both commands ran fine.
Rebooted.
Did not solve the issue.

Secure boot was disabled before, now shows as enabled. Can you disable it in Bios?

Also, now shows a wifi soft block. Try:

Code: Select all

sudo tee /etc/modprobe.d/blacklist-acer-wmi.conf <<< "blacklist acer_wmi"

Reboot

I know it was disabled.
I enabled it just to see if that works out, it did not. I turned it back off.
I ran your command and rebooted.
Did not help.

When I do

Code: Select all

sudo iwconfig wlp3s0 power off

and then do:-

Code: Select all

 rfkill list ; iwconfig ; mokutil --sb-state

I can see that Power Management: off

But after reboot it turns back on again.

Code: Select all

SecureBoot disabled

And the issue remains. Any way to permanently turn off power management?

[sleeper12]

I don't know why that command won't keep it off. Maybe JeremyB will have another idea.

Power Manager is still not turned off.
JeremyB please provide some help brother.
Stuck with this since multiple days.

I ran this command because you asked me to and it did not solve the issue, I was just worried, will this not cause any problem right?
