Raspberry pi 5 sometimes loses wireless connection (self.selfhosted)

This is a problem I have been having for a while and I thought I had fixed it but it has recently returned.

Sometimes my raspberry pi will lose connection on a random device. Sometimes it's tailscale, sometimes it's wlan, sometimes it's both. It still shows as connected in my router even when it is unreachable. When I can access it through one device while the other is down I check for errors but can't see any. If left alone for long enough it will fix itself (today it fixed itself after 6 hours) or I can reboot if I still have access to ssh through a working device.

To fix it last time I fixed wireless localisation settings (it was set to us instead of gb) but it being fixed after that change might have been a coincidence.

My only idea for why it doesn't always work is because of a range extender I have upstairs (where the pi is) which is connected to the network using fritz! mesh. I think it's a bad idea since it is placed very close to the main router (almost directly above) but my dad insists on having it.

Just happened again, no errors in the network manager log. I am running an up to date version of raspberry pi os. The only bare metal program I am running is pihole, the rest are in docker. I'll send a list of the containers when I can.

It's more important to get that dmesg output AFTER an event happens, but before a reboot. What you're running doesn't matter much unless you have live metrics of their behavior or resources.
