Arch Linux

This problem drives me crazy. It's better not to use wireless connection. I have searching solution for months but no luck yet.

I have noticed three things so far. First is only 5GHz connection produces this fault, 2.4GHz looks good.
Secondly linux-firmware package does not contain the latest firmware for my card, so I downloaded it from the Intel website (https://downloadcenter.intel.com/download/17045/Intel-Drivers-for-Linux-) and copied to the /usr/lib/firmware directory.
And finally it's not enough to have the latest firmware in the directory mentioned before, the latest kernel needs to be run in order to load the latest firmware. (It's kind of hard-coded which kernel version depend on which firmware.).

Hmm. I downloaded iwlwifi-3945-ucode-15.28.2.8 (not latest) from https://wireless.wiki.kernel.org/en/users/drivers/iwlegacy and copied it to the /usr/lib/firmware directory. Wireless connection seems to be more stable now but it doesn't solve issue.

Any fix?

Same Problem here with the new 5th Gen Lenovo X1 Carbon and Intel 8265 on a fresh Arch install. Happens on both core/linux-firmware 20170309.695f2d6-1 and aur/linux-firmware-iwlwifi-git 20160725.26a5c2a-1.

Tried netctl and NetworkManager. Netctl sometimes work for a few minutes before it crashes, NetworkManager is chrashing after a few seconds.

Same problem here with a Lenovo T400 and the current Kernel, chipset is WiFi Link 5100 AGN.

If I boot the current LTS-Kernel or downgrade to the latest Kernel of the 5.0.x-branch (5.0.13) all works well for me. Any suggestion to solve the problem? Stay on LTS- or a outdated kernel is not an option,

Until yesterday I was on lts-kernel 4.19.101-1 and it worked without issues. After latest upgrade to lts-kernel 5.4.19-1 I got the same problem now also on the lts-kernel. It most happen on system updates or synchronization between two systems using rsync. Even after intensive searching I found so for no solution for this problem, so every help is appreciated.

Intermittent OOPS of the iwlwifi interface with interruption of the network occurs whenever the interface is loaded. More frequent on 5 Ghz rather than the 2.4 Ghz frequency networks.
