Iv been faceing this problem for a while and iv ran out of options i can think of. Iv turned off power managment, tried switching drive to the dkms version, did half of what was on here: https://easylinuxtipsproject.blogspot.com/p/intel-wifi.html#ID3.
Here is lshw -C network:

In terminal run wget -N -t 5 -T 10 https://github.com/jeremyb31/wireless-info/raw/master/wireless-info && chmod +x wireless-info && ./wireless-info press y when asked to upload results then post URL

sudo iwconfig wlp39s0 power off

#

nmcli connection modify ca317529-a3d0-48a6-8f57-1be572713dd3 802-11-wireless.powersave 2

#

Might want to disable the firewall in linux

#

Yes and UFW/GUFW isn't really needed when you are behind a router using NAT

wet grove
#

Alright. I hope this sticks. I'll report back if it DCs again but i can already see a improvement in speed

thin mortar
#

You can also try echo "options iwlwifi 11n_disable=8"|sudo tee /etc/modprobe.d/iwlopt.conf

#

That one will take a reboot to take affect, if it causes a problem sudo rm /etc/modprobe.d/iwlopt.conf but I use that for my Intel wifi

UFW= uncomplicated fire wall, GUFW is the GUI for UFW

Sometimes I dont know why people say Linux is hostile to new people. I exhale and you appear. Il be back if it starts doing it again but super appreciated!

thin mortar
#

Some people get hostile when new people don't follow instructions or answer questions. I am more hostile to people posting garbage info on youtube and the guy that wrote easy linux tips

wet grove
#

ya. Online sources can be extremly spotty and unreliable

#

forum posts from 2017 dont help either

thin mortar
#

The guy that does easy linux doesn't seem to understand DKMS and he has been around Linux at least as long as I have. Should limit a search to a time of a year or less

Can you change the wifi router setting so it uses channel 1 rather than auto?

wet grove
#

like on the physical router or....

wet minnow
thin mortar
#

Yes, router settings page with web browser with address 192.168.1.0 or maybe 192.168.1.1

wet grove
#

i do not have access to that unfortunatly

wet minnow
#

you should just have to type that ip in a browser window

wet grove
#

oh ok

wet minnow
#

from your local ip it seems like 192.168.1.1 should work

wet grove
#

says cant be reached

wet minnow
#

are you connected to the access point?

#

if yes then try the other ip

thin mortar
#

Might want to go into Network Manager settings for your connection and choose a MAC for BSSID as it is switching between the 2.4 and 5GHz on the wifi

wet grove
wet minnow
#

Also make sure you're relatively close to the access point and the signal strength is > -70dBm

#

some drivers don't handle low signal strength well

wet grove
#

link quality 58/70

wet minnow
#

5 or 2.4 Ghz?

wet grove
#

i should also mention this has been happening rather recently

wet grove
wet minnow
#

ok

#

may i have the full output of dmesg ?

wet grove
wet minnow
#

yea it is supposed to be

#

paste it here. Discord will convert it into a file automatically

#

iwlwifi filled like half of this log

#

it's logging a ton of disconnecting from AP *AP* for new auth to *AP*

#

i think it's trying to connect to 5Ghz and 2.4Ghz channels when it's most convenient

wet grove
#

sounds like we at least have a definitive reason for the random disconnecting

wet minnow
#

i had the same issue btw

#

fixed it by choosing a fixed channel

#

choose either 2.4Ghz or 5Ghz in the Advanced Netowork Config application for your connection

#

2.4 is the most stable

thin mortar
#

Might want to try kernel 6.14 using Grub at boot with Advanced Options

I would try booting an ISO with Mint 22 using the 6.8 kernel then

wet grove

i think its safe to say that the problem as heen solved for now. @thin mortar @wet minnow you both are wizards and thank you for helping identify the issue and dealing with my noob arse
