5Ghz wifi connected without internet, 2.4Ghz works


UPDATE: Seems the issue is with the router, I'm having the same issue in windows 10, but curiously not on my android phone. Sorry for wasting time!

Just installed Garuda, during installation and immediately after 5ghz wifi worked. After install i was prompted to update the system and after that it connects without internet. Is this a driver issue? Can I roll back or update the driver?

I have not attempted any fixes. Trying to figure out how to see drivers etc.
Apologies if this topic already exitsts could not find it. The wifi card is a TP Link AX3000.

Many thanks

First can you add ~~~ before and after your terminal output.
Second i would reboot the machine as you have not done so after updating
What have you tried so far?
Have you checked your wireless network settings
If you are far away from the access point you will find it will prefer 2.4 instead of 5


I can see some recent regressions related to your driver (iwlwifi) recently.

Maybe, as a first troubleshooting test, you could try moving to the linux-lts kernel.


Thank you for your quick reply! I have tried both a restart and changing to the LTS kernel without any difference.

Thank you for replying!
I have made sure the 2.4 is not preferred. The signal strength is very good. The Access point is not far.

Try lowering the channel on the 5 GHz band. Some wifi adapter's have problems connecting on the higher router channels. Select a 5 GHz channel below 40 in your router, (such as 36) and see if you can then connect properly.


UPDATE: I reolved the issiue in windows by changing the channel width from 40 to 20MHz in the adapeter options. How do i go about doing this in Linux?

Preferably you want to do this in your router's settings.

I don't have access to those :frowning: I'm renting an apartment where there is only wifi.

As your wifi was working correctly at one point, you may be able to correct your wifi's behaviour. You should perform the following suggestions first as some of these may correct your issue:

Is your computers BIOS up to date?

If not be sure to update it, as doing so may correct your problems in both Linux & Windows.

Install and test different kernels, running connectivity tests on each. I would suggest starting with the linux-hardened and linux-mainline kernels. After installing a new kernel reboot and select the alternate kernel from the grub advanced boot menu at startup.

Install and test the newest Linux firmware available:

sudo pacman -Syu linux-firmware-git

After installation reboot.

Try temporarily disabling Bluetooth to see if your connectivity improves.

If after testing all those fixes nothing helped try running this command and the see if you can connect properly.

sudo -u $USER /bin/bash -lc 'lsmod | grep -o -e ^iwlmvm -e ^iwldvm -e ^iwlwifi | xargs sudo rmmod && sleep 3 && sudo modprobe iwlwifi 11n_disable=8 bt_coex_active=0'

I've been able to resolve the issue across win and Linux by enabling a random MAC address. I don't know why this works, but I imagine it's a router issue.
Thank you for you kind help regardless!
