So, allow me to start by saying I have been using Debian since debian 9 was out. I have used it on the same laptop with the same wifi card. the laptop is an Asus K53-Z and the wifi card is a Intel 7260 rev. 73 (2 channel 866mhz AC class card) My wireless access point is an Asus RT-AX1800S
On Debian 9/10/11 I could leave my wireless access point set at 80mhz wifi channel. This works fine on Debian 9/10/11. But on Debian 12 this causes my wifi to stop after about a minute or so. The only way I can "fix" this is to go into my routers setup page and change the wifi channel bandwidth from 80mh to 40mhz. (20mhz also works).
To be clear, when my wifi stops working, it is only stopped working on my laptop, all the rest of the wifi devices continue to work normally.
Steps to troubleshoot: After experiencing this issue with debian 12, I live booted a debian 11 dvd to test the wifi, and sure enough it works fine on 80mhz channel bandwidth. But if I boot back into debian 12 it will quit again after 1 minute or so unless I change the channel bandwidth back to 40mhz.
I tried changing wifi channels from 36 to 48 to 149. It crashes my wifi on all channels if the bandwidth is set to 80mhz.
I disables power save in the debian terminal but this had no effect on crashing during 80mhz bandwidth.
No other devices in the household have issues with 80mhz bandwidth except this one laptop, and only if it is booted into debian 12.
So I gotta think that something changed between debian 11 and debian 12 that is causing my issue, but I am not smart enough to figure it out. If you guys would like some logs let me know which ones and thank you for any help.
Update: After many, many hours of internet based investigating, I was able to fix the issue by adding a file to /etc/modprobe.d called iwlwifi.conf The contents of the file are very simple, just : "options iwlwifi enable_ini=0" and then restart debian. This fixed it. It's been 6 hours now and no more wifi crashes on 80mhz channel bandwidth!
