No Wifi on freshly installed system

Post by laminateur »

Hi,

I just installed Mint Mate 20 on my new thinkpad which definitively has wifi.

The system though only shows me ethernet.

I restarted twice, in the bios things are ok.

How do I fix that?

Thanks for your help!

No Wifi on freshly installed system

Post by laminateur »

Hi there,

I just installed Mint Mate 20 on my thinkpad.

The wifi wouldn't show up, even after 3 restarts. I checked the bios, it's all ok there.

Here's what the terminal says about the system:

Looks like the system doesn't see the wifi. How do I change that? The laptop certainly does have wifi....

Thanks a lot!!

Didn't work. Wifi is still inexistent.

How do I look up in the terminal, if the system can detect the wifi hardware?

*edit*

I just tried the live version again. It also doesn't show the wifi option.

Your ThinkPad T580 should be showing its Intel 8265 wi-fi chipset, which Mint supports -- but the OS doesn't see it.


Open a Terminal (Ctrl-Alt-T), then copy-and-paste this command to search for the chipset...

Code: Select all

lshw -C network
Copy the output of that, to paste into a reply here.


For good measure, let's make sure the little NIC won't snooze: Copy-and-paste this command-line, to disable automatic wi-fi power saving mode...

Code: Select all

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


Can you open the laptop and make sure the wi-fi module card is well-seated and secured in its M.2 connector?

I did that. No changes. Wifi still not there.

Well, I could. But that's the last thing I'll try. Before that I think I will use an ethernet cable. The laptop is mainly for stationary use anyway. But it would be great, if the wifi worked anyway.

I will now install the live version of an older distribution. Maybe that works...

Before doing that, perhaps try installing the Hardware Enablement (HWE) kernel extension...

Code: Select all

sudo apt install --install-recommends linux-generic-hwe-20.04
Using a rolling-update model, the HWE stack pulls in whatever new hardware support that gets added to more recent and future kernel releases. HWE is intended to prevent the LTS (Long Term Support) kernel from falling too far behind the most recent kernel and X additions for new PC hardware.


You could also try a LiveUSB/DVD created from the Edge ISO, which also has a wider variety of hardware support, plus the more recent kernel 5.8.


If the issue is a loose internal component, then software won't make a difference -- but there's always the option of plugging a wi-fi dongle into a USB port.

Thanks for your help so far.

Both the current Ubuntu and the last LTS version don't show me that "no wifi adapter found".

Looks like it's something on the hardware side.

Do you know if it's possible to check in the bios whether the wifi card is ok?

I'm not familiar with the ThinkPad BIOS features.

If there's a way to enable/disable the wi-fi in the BIOS, it might not serve a diagnostic role -- perhaps just indicate that the wi-fi can't be enabled, if the system can't see it (as absent, loose, or dead).

.

Actually, there's something we didn't try -- stuffing the device driver...

Code: Select all

sudo modprobe iwlwifi
Then look again...

Code: Select all

lshw -C network

No, still nothing.

According to this image from 2018, there should be something in the BIOS. But there's nothing like that in mine. Hmm....

Try resetting the Bios to defaults.
