network keeps disconnecting seemingly randomly

my network keeps disconnecting at random intervals
After a bit of searching i found out that my wifi card is ath9k but after that i got stuck

Hi, and welcome to Arch!

For a first question, you're doing great. However, on these forums we expect a little more information coming from you. Give the link in my signature a read, and we can go from there.

After you've done that, it would be useful if we could get:

Output of:

journalctl -b | grep -Ei 'wlan|ath|firmware|wpa|network'

Output of:

ip link
iw dev

Your NetworkManager service status:

systemctl status NetworkManager

Any recent system changes; for example, if you just added a new kernel, router, configuration, or something else

Also check out the Arch Wiki pages on:

https://wiki.archlinux.org/title/Genera … al_support
https://wiki.archlinux.org/title/Wirele … leshooting
https://wiki.archlinux.org/title/Ath9k
https://wiki.archlinux.org/title/NetworkManager

Once you provide the logs above, we can narrow down whether this is a driver, power-saving, regulatory domain, or configuration issue.

Hi, thanks for the tips on answering questions, not really used to searching for answers on forums, i tend to diy and trying to get to solutions myself. Also dont really know how to insert a code into the comment like other people do such that it is a different backround (ill try to space it out from the rest of the comment).

I ve had this problem ever since i installed arch a few months ago but i thought it was just a problem with my signal. After finding out other people had the same issue i ve come to the conclusion that my hardware has nothing to do with it and it may be caused by conflicting services such as network manager and iwd that are fighting for network privliges.

... use a paste site

and disable systemd-networkd you have conflicting network managers enabled

send the link generated by this command:

systemctl list-unit-files --state=enabled | curl -F file=@- 0x0.st

Also disable iwd and see https://wiki.archlinux.org/title/Networ … Fi_backend if you want to use it as NM backend.

Yes, I think your issue is multiple conflicting network management programs running at the same time. After looking through those logs, I spotted these lines:

 Dec 11 22:04:12 archlinux systemd-networkd[298]: Foreign process 'NetworkManager[445]' changed sysctl '/proc/sys/net/ipv6/conf/enp1s0f0/disable_ipv6' from '0' to '1', conflicting with our setting to '0'.

By the way, I’m putting these code blocks in by writing

[code] text_goes_here [/code]

.

These seem to suggest that you have both systemd-networkd and NetworkManager enabled. To confirm this, we can check

# systemctl status NetworkManager
# systemctl status systemd-networkd

If both of these are enabled, choose one to continue with. I’ve always used NetworkManager, but both of them have their own benefits! You can read about them on the Arch Wiki at:
https://wiki.archlinux.org/title/NetworkManager
https://wiki.archlinux.org/title/Systemd-networkd

I would try

# systemctl stop systemd-networkd systemd-resolved # Stop services
# systemctl disable systemd-networkd systemd-resolved # Disable them from starting at boot
# systemctl enable NetworkManager # Ensure NetworkManager is active

Of course, switch around the disable and enables if you want to do the other option.
