what does that mean?

Hi @testingcont,
Can you execute the terminal command inxi -FN and put the output in the post?

In order to help you we must know something about the wifi adapter.

Hope it help, regards.

Hi, @testingcont,
Your wifi is down, although is present.
You can check whether is blocked or not with the following terminal command:
sudo rfkill list all.

I also suggest you to look at this couple of post, in order to try to solve your problem.
‘Wireless Connection randomly disconnects, restart is required’

‘Wifi shows its connected for 5Ghz radio but will not resolve an address, but connecting with 2.4Ghz Radio always works’

Hope it help, regards

Hey! Doesn’t seem to be blocked, but the wifi works on both windows and Linux Mint

Try:

sudo systemctl restart NetworkManager
nmcli networking on
10

Same thing, only now it shows “limited connectivity”

11

Could you also post the vendor and ID (chip ID)? Without it, it would really hard to find any possible solution if that one is really exotic…

inxi -Nazy

A Thinkpad has a wifi toggle FnF8.

Also check in the firmware if wifi-card is enabled.

There is specific power modules for Thinkpad is in the repo - so you should check your power settings both within KDE but also tlp. Install tlpui to get a GUI overview over the settings.

Device-2: Intel Centrino Advanced-N 6205 [Taylor Peak] driver: iwlwifi

ok @testingcont , at least the wifi is not exotic and should work:

I guess there is more investigation needed then…

Could you run:

journalctl -f

and then try to connect? Any useful information in the log?

Quite a lot.

I also tried to follow this guide:this

and when I tried

/etc/modprobe.d/iwlwifi.conf

the file doesn’t exist.

16

You need to create that text file. :wink:

17

Also check in the firmware if wifi-card is enabled

Can you help in more details how do I do that?

18

Just a blank text file? What would that accomplish?

19

Of course with content xD

Your can try some other options like:

options iwlwifi 11n_disable=1 swcrypto=1

https://wiki.archlinux.org/index.php/Network_configuration/Wireless#iwlwifi

More information with:

modinfo iwlwifi

ok… open nano and create a new file:

sudo nano /etc/modprobe.d/iwlwifi.conf

then copy and paste this:

into that file and with CTRL+S you save the file. Close with CTRL+X.

Reboot…

It works :smiley:. Thank you so much. Was the missing file the problem? I tried a bunch of other things

23

Nice :+1:

I guess not, but iwlwifi is a universal driver and some cards need options to be disabled sometimes. swcrypto is enabled now and it seems the hwcrypto does not work well on that card, or maybe not possible? :man_shrugging:
