WiFi disconnect/reconnect every 10 minutes.

found same issue on reddit: https://www.reddit.com/r/archlinux/comm … 0_minutes/

My Situation:

• dell ins 15 7590:  Intel(R) Wireless-AC 9560 160MHz + iwlwifi + kernel 6.6.26-1-lts + kde 6 (all pacman -Syu to latest)

• only iwd(built-in dhcp) + systemd-resolved(dns) for wifi connect. (checkd systemd.service to avoid conflict with other nms)

• I use networkmanager or systemd-networkd before, also static ip. all failed. so I switch to iwd, nm will notify when failed.

• tlp/modprobe-iwlwifi : power_save=off (use AC mode always)

• wireless-regdb: my location correct.

• shutdown bluetooth and usb hub for test. nothing help.

• wireshark for dhcp info: the release time is 7 days  (I think a good dhcp client will request before the lease time)

Weird thing: 
Early time, i just use win11, and the wireless network do disconnet randomly, but with the time, it become stable(may be power_save off) for 3 years.  Now, I use dual os (arch on another ssd), It disconnet/reconnect periodically(exactly 10 mins) on arch to the same wifi ssid. I even check the time (dual os time isn't right, i ref the arch wiki to make win11 use utc time).

some outputs:

I don't know how to solve this. It has been a week( I installed arch). Wonder kernel problem or iwlwifi problem or my config and dell 7590? Need Hlep!

Re: WiFi disconnect/reconnect every 10 minutes.

Now, I use dual os

3rd link below. Mandatory.
Disable it (it's NOT the BIOS setting!) and reboot windows and linux twice for voodo reasons.

Reason 4 is "Disassociated due to inactivity", try to disable tlp and intel undervolt to see whether it's an outfall of powersaving efforts
(Doesn't seem roaming, the signal would be too good for that)

Re: WiFi disconnect/reconnect every 10 minutes.

thx for reply.

• win11 didn't has hibernate func in dell 7590. just modern sleep (microsoft). Anyway, I do manuly.  power /H off

• my boot order: 1. arch 2. win;   When in one os, I can sure that shutdown/reboot. not hibernate.

Try disable tlp + intel-undervolt: still disconnect
At start, iw show power_save on.
There is wierd:  in modprobe.d/iwlwifi.conf , I passed option to iwlwifi, then mkinticpio -P, then reboot.
my wifi netcard only support wifi 5. so I disable wifi 6/7. explicit require power-save:off. But didn't affect kernel/module

Re: WiFi disconnect/reconnect every 10 minutes.

win11 didn't has hibernate func in dell 7590

Windows can hibernate everywhere and defaults to fast-start, which is hibernation in disguise.
Because of the anecdote where windows originally did the same, I'd not ignore that - radio is the by far most common victim of this situation.

This includes t he reboot-voodoo-dance.
You also may want to reboot the AP (wifi router) to get rid of stale connections there.

If all of this doesn't work, please post the entire journal

sudo journalctl -b | curl -F 'file=@-' 0x0.st

Whatever else is going on during those ten minutes might be relevant.

b/c of "Disassociated due to inactivity" - does this also happen when you keep "ping -i 30 google.com" in the backgroung (pings google every 30s)

Re: WiFi disconnect/reconnect every 10 minutes.

yeah. I check win11 power managemnt in control pannel. There is no fast-start checkbox and hibernate. so win11  thing may be done.
Actually, in win11 no traditional S3 sleep option(for my case. https://wiki.archlinux.org/title/Dell_I … 0)#Suspend     I didn't add kernel cmdpara cause i use this laptop as pc. no need sleep. )

I am not familar with how wifi work in linux. And I totally agree with you:  thank for your time.

Whatever else is going on during those ten minutes might be relevant.

Finally, I switch to anoter wifi ssid (from a tplink route; original one is modem built-in wifi ssid -- win11  wifi work well with this wifi and also android phone). Tplink wifi ... en, not bad. It can connect for a long time(2 hours+ now) without disconnect. If still sucks, i will use a 'RJ45 USB Cables & Adapters' as a trick

So, I just guess it's related with kernel iwlwifi driver, maybe.  Until next upgrade(kernel or some huge), wish work well. Now, let it go.
Again, thx a lot.
