Hi,
My wifi is consistently getting disconnected after about half an hour of usage. Any ideas regarding what I could do to fix it?

Things I have tried to give you guys information:

Try this one

echo "options iwlwifi 11n_disable=1" | sudo tee /etc/modprobe.d/iwlwifi-11n.conf
sudo modprobe -rfv iwlwifi
sudo modprobe -v iwlwifi

I tried this, This worked for a day, and then disabled my wifi completely, after restarting my system. Is there any other info you need to give me a more accurate solution, thanks in Advance, Sorry for the delayed response, my screen stopped working(hardware issue), and I had to give my laptop for servicing.

Please help me, the issue has become significantly worse, i now disconnect from wifi within 10 minutes of restarting my system, and to re enable it, i need to restart my system again

darthvader1234,
While I am only a network novice (there are others who are network gurus of the Nth order), in reviewing your wireless-info.txt, I noticed:

56. SecureBoot enabled
388. Region: Atlantic/Reykjavik (based on set time zone)
381. country 00: DFS-UNSET

Recommend:

In BIOS/UEFI change to SecureBoot disabled

Region and country should correspond. If you are really in Iceland, from a terminal

sudo iw reg set IS
sudo sed -i 's/=.*/=IS/' /etc/default/crda

The first line sets the country code temporarily while the second line sets it permanently.
Country codes can be found in /usr/share/zoneinfo/zone.tab

I hope this helps.

I am not in Iceland, I was there at the time of installation of Ubuntu. I am now in India, And have run the commands with the Appropraite Zone, Let me see if the problem persists and post an update here soon

[darthvader1234]

Unfortunately, The problem persisted, but Now I can stay on a connection for 30 minutes or so before getting kicked out. I have updated the pastebin after rerunning the code(I have also re enabled secure boot after making the changes)

darthvader1234,
There is another issue in your wireless-info.txt

58  ##### lsmod #############################
60.  libkmod: ERROR ../libkmod/libkmod-module.c:1931 kmod_module_get_holders: could not open '/sys/module/windrvr6/holders': No such file or directory

This is what mine looks like,

##### lsmod #############################

iwlmvm                364544  0
mac80211              778240  1 iwlmvm
iwlwifi               286720  1 iwlmvm
cfg80211              622592  3 iwlmvm,iwlwifi,mac80211

Unfortunately, I, a novice, have no recommended solution for you, but maybe gurus, chilli555 or jeremy31 will respond your post.
