My wifi connection keeps disconnecting frequently. It's pretty exhausting during meetings. I've searched how to resolve this bug and I found that it can be related to the kernel version (22-04-wifi-keeps-disconnecting-for-a-few-seconds-frequently). The actual kernel version is 5.19.0 :

(base) claire@claire:~$ uname -r
5.19.0-32-generic

I keep trying to downgrade the kernel (5.17.5 ?) with Ubuntu Mainline Kernel Installer following this tutorial How to downgrade the Ubuntu kernel.

However I have a problem during the step 3 :

Step 3: When you’ve finished installing the kernel, reboot. Then, on the Grub boot screen, choose “Advanced Options for Ubuntu” and load the downgraded kernel.

While I chose the kernel with Grub, I've got the error : error you need to load the kernel first.

Is it the right thing to do ?

Here the output of lspci -knn | grep Net -A3 :

0000:00:14.3 Network controller [0280]: Intel Corporation Alder Lake-P PCH CNVi WiFi [8086:51f0] (rev 01)

Some have reported success in editing /etc/modprobe.d/iwlwifi.conf and adding the following line.

options iwlwifi 11n_disable=1 swcrypto=1

You'll need to unload/reload the driver - or more simply restart the system - for the change to take effect.
