With no indication what so ever my internet connection via wifi either slows down significantly or drops to 0 bits completely. No wifi connection is lost. So far only restarting the network manager via systemctl solves the issue for a couple of minutes before it drops out again. This is a fresh install though the problem started about a week ago on a older installation of mine. So far I have tried turning off Bluetooth entirely and switching from wpa_supplicant to iwd. Not sure where else to look to see if stuff is error-ing out, my windows install seems to work fine and I don’t have access to Ethernet so I can’t test if there is a issue there.
See if it’s reproducible on the mainline kernel vs the LTS kernel. Also check if you’re using 2.4Ghz or 5GHz for your router. If you’re router is using 2.4Ghz for example, anytime you use your microwave, that will interfere with the wifi until the microwaves job is done, but using 5Ghz isn’t affected by microwave use. So use a different kernel and/or watch what you cook. This may or may not be useful

Unfortunately it does occur on the LTS kernel as well as the mainline. No microwave either though I should mention I am using 5Ghz.
I use at 2.4 GHz on my system. Check whether it helps.
I told this because 5 GHz won’t work here.
Without any information whatsoever about which wifi chip you are using everything at this point would be pure conjecture.
If I had to hazard a guess, I would say this may be a power saving issue. If your wifi driver has the option, I would disable power saving via a driver config file in /etc/modprobe.d.
You could also disable power saving via a Network Manager config file.
For an informed opinion, you would need to provide at the minimum:
inxi -naz
Some logs would also be helpful.

Hi AlphaClover,
We really need to know some details about your setup:
(1) System (run below in terminal).
inxi -FAZ --no-host
(2) Which router and model.
(3) If you boot off the Endeavour Live image USB … are you seeing the same issue when using wifi?
(4) If the computer is dual booted with Windows, are you seeing an issue there with wifi?
Thanks.

Sure thing, this is what the inxi -Faz --no-host outputs.

My wifi and internet work perfectly fine on windows with no slowdowns or dropout issues.
For router stuff, I am at college right now but its a aruba access point which I have had no problem with for the past year I have been here so I have no reason to suspect it.
Not sure my driver has the option, no configs or anything were in the modprobe.d file. I just posted the inxi above in the previous post as well.
To load the iwlwifi module with power saving features disabled use:
nmcli networking off; sleep 1; sudo systemctl stop NetworkManager; sleep 1; sudo lsmod | grep -o -e ^iwlmvm -e ^iwldvm -e ^iwlwifi | xargs sudo rmmod; sudo modprobe -r mac80211; sleep 3; sudo modprobe iwlwifi power_save=0 d0i3_disable=0 uapsd_disable=0; sleep 1; sudo systemctl start NetworkManager; nmcli networking on; sleep 1; nmcli r wifi off; sleep 1; nmcli r wifi on

Seems to be working so far, weird how it just started out of the blue a week ago. Thanks!
That is not a permanent solution, it only lasts until you reboot.
To make disabling the iwlwifi power saving options permanent, run the following command:
echo 'options iwlwifi power_save=0 d0i3_disable=0 uapsd_disable=0' | sudo tee /etc/modprobe.d/iwlwifi.conf
Then, reboot.
You’re welcome, and I’m glad that helped.
