Recently i have installed Linux mint 20 in my Lenovo E41-25. Previously it was installed with Debian and Windows 10 dual boot. Due to some hard disk problem i installed Linux mint 20 after that Windows 10. During installation of Linux Mint 20 Wifi worked. After older version of windows 10 installation, win 10 OS destroys all drivers and i reinstalled the latest win 10. Now, wifi is working in win 10, bu not in linux mint.

Please help and give instructions step by step to solve this issue. Now i am using external USB WiFi dongle adaptor

Is the driver available in Driver Manager? I think it's the ath10k_pci you need.

If not, what does this show:

Result: ath10k_pci = 0

[sleeper12]

I wonder if it just needs to be loaded, try:

Code: Select all

 sudo modprobe ath10k_pci 

[sdivahar]

typed "sudo modprobe ath10k_pci" in terminal, but no response.

[sleeper12]

Ok, hopefully someone will know how to install that driver, but not me.

[sdivahar]

Omg

[sdivahar]

Linux experts, plz help

[sleeper12]

See if this does any good:

Code: Select all

 sudo apt update 

Code: Select all

 sudo apt install --reinstall linux-firmware 

Reboot

Another thought, if secure boot is enabled, disable it in Bios. This will tell:

Code: Select all

 mokutil --sb-state 

[sdivahar]

1. sudo apt update - done
2. sudo apt install --reinstall linux-firmware - done
3. mokutil --sb-state - Secure boot enabled

I'm using Legacy boot. Not able to fine "Secure boot" in bios.

I have updated latest BIOS in Lenovo E41-25. But no such "Secure boot" option in BIOS

[sdivahar]

1. sudo apt update - done
2. sudo apt install --reinstall linux-firmware - done
3. mokutil --sb-state - Secure boot disabled

I have changed the boot mode from legecy to UEFI and the Secure boot is disabled by default.

Unless someone has a better idea, I'd say reinstall Mint 20. If wifi works in the live session, it should work when installed.

[sdivahar]

Yes, I have tried that with live usb also. But WiFi not working.
I have installed Linux mint after windows 10, with all updated drivers. In windows 10 WiFi working good. But not in Linux?

[sleeper12]

You said wifi worked before in a live session:

During installation of Linux Mint 20 Wifi worked.

Now it doesn't work in live session?

[sdivahar]

WIFI NOT WORKED
During installation,
after installation,
in live usb,
after various Mint 20 updates
and forum suggestions tried in terminal.

No WIFI

Near the very bottom of this webpage is a section titled "No wired or wireless internet on a dual boot computer" and it says
If you have a dual bootable PC with Windows, and you've just used Windows, you may not get an IP address after a reboot in Linux. And so no internet connection. It then explains some things to try.

Given that you say there was at least one time it was working in Mint, this seemed like a possible explanation to me and seems worth trying.

It's #3 on that page if that helps.

[sleeper12]

It seems to me you need to get the ath10k_pci driver, but I can't find a way to do it. Unless someone knows how, you might have to settle for using a usb wifi adapter.

[sdivahar]

No, WiFi didn't work (not detected) during installation. After that I tried Live USB (bootable) for WiFi drive detection. But, that method also not working
