network connection drops, can only be fixed by reboot

Hi thanks for reading. This is the first problem I haven't been able to solve on my own since switching to Arch, so help greatly appreciated.

I should preface by saying that I've been using this setup for at least a year now without problems. This issue started happening suddenly about 3 days ago without an apparent correlation. I didn't add new software or do updates, change configuration, run out of space, etc.

Basically, after a fresh reboot my network connectivity is normal, I can browse the internet etc. This will last from 5-20 minutes and then drop. Once dropped, I cannot seem to do anything to restore the connectivity (ie, restarting services). I can only reboot the machine and continue the cycle :)

None of the other computers on this network are experiencing any issues.
I have since done a full Syu and the problem still persists.

I am using systemd-networkd and systemd-resolved and connecting over wireless. For that I also use iwctl/iwd and that is it. (iproute2 is involved in there somewhere)

OK. I'll divulge some configs and logs. I would be pleased to provide additional information, just ask!

/etc/systemd/network/25-wireless.network

[Match]
Name=wlan0

[Network]
DHCP=yes

[DHCP]
RouteMetric=20

If I check the status from systemd-resolved *before* being dropped, I get this:

$ resolvectl status
Global
           Protocols: +LLMNR +mDNS -DNSOverTLS DNSSEC=no/unsupported
    resolv.conf mode: stub
Fallback DNS Servers: 1.1.1.1#cloudflare-dns.com 9.9.9.10#dns.quad9.net
                      8.8.8.8#dns.google 2606:4700:4700::1111#cloudflare-dns.com
                      2620:fe::10#dns.quad9.net 2001:4860:4860::8888#dns.google

Link 2 (enp59s0)
Current Scopes: none
     Protocols: -DefaultRoute +LLMNR -mDNS -DNSOverTLS DNSSEC=no/unsupported

Link 4 (wlan0)
    Current Scopes: DNS LLMNR/IPv4 LLMNR/IPv6
         Protocols: +DefaultRoute +LLMNR -mDNS -DNSOverTLS DNSSEC=no/unsupported
Current DNS Server: 192.168.0.1
       DNS Servers: 192.168.0.1

If I check after, I get this:

$ resolvectl status
Global
           Protocols: +LLMNR +mDNS -DNSOverTLS DNSSEC=no/unsupported
    resolv.conf mode: stub
  Current DNS Server: 1.1.1.1#cloudflare-dns.com
Fallback DNS Servers: 1.1.1.1#cloudflare-dns.com 9.9.9.10#dns.quad9.net
                      8.8.8.8#dns.google 2606:4700:4700::1111#cloudflare-dns.com
                      2620:fe::10#dns.quad9.net 2001:4860:4860::8888#dns.google

Link 2 (enp59s0)
Current Scopes: none
     Protocols: -DefaultRoute +LLMNR -mDNS -DNSOverTLS DNSSEC=no/unsupported

Link 4 (wlan0)
Current Scopes: none
     Protocols: -DefaultRoute +LLMNR -mDNS -DNSOverTLS DNSSEC=no/unsupported

So I can see that wlan0 goes from having its own DNS Server setting from the router, to using the Global setting which it got from falling back.

Here are the systemd-resolved configurations...

/etc/resolv.conf (symlinked from /run/systemd/resolve/stub-resolv.conf)

nameserver 127.0.0.53
options edns0 trust-ad
search .

So systemd-resolved is in stub mode, which has been great until now. It would be nice if I didn't have to switch away from this.

/run/systemd/resolve/resolv.conf

nameserver 192.168.0.1
search .

I don't think this file is symlinked anywhere or know if it even gets used, but this does define the router's nameserver so that's probably where that comes from. (I didn't do it!)

/etc/systemd/resolved.conf

[Resolve]

#ResolveUnicastSingleLabel=no

Everything in this one is basically commented out, so I don't think it particularly contributes. But I am a bit confused about something. After the connection is dropped and I check resolvectl status it shows that it is using 1.1.1.1#cloudflare-dns.com as the Current DNS Server and also shows all those other DNS Fallbacks. I cannot for the life of me find where those are coming from nor where they are specified. This file seems to be the only place that these are mentioned. If anyone could clear up where these are being injected from, I'll sleep better at night!!

Lastly I have my logs from doing journalctl -f ... I removed lines that did not seem relevant.

I looked this over and while it says bad things, nothing really jumps out as inciting a solution. Not sure if the behavior of the hostname service is an indication of something.

Well. Thank you very much if you made it this far. This issue is really plaguing my productivity and I am entirely grateful for assistance.

Re: network connection drops, can only be fixed by reboot

Cloudflare is hardcoded as fallback DNS in resolved.
Please post the output of

find /etc/systemd -type l -exec test -f {} \; -print | awk -F'/' '{ printf ("%-40s | %s\n", $(NF-0), $(NF-1)) }' | sort -f

and a complete system journal "sudo journalctl -b | curl -F 'f:1=<-' ix.io" because if you knew for sure what was relevant, you'd not be asking here, right?

networkd records a carrier loss and iwd a deauthentication, but not by the AP.
https://bbs.archlinux.org/viewtopic.php?id=272848 was (apparently) down to roaming issues.

Iff there's no other problem, I'd also try wpa_supplicant, but first let's see the actual data.

Re: network connection drops, can only be fixed by reboot

But I am a bit confused about something. After the connection is dropped and I check resolvectl status it shows that it is using 1.1.1.1#cloudflare-dns.com as the Current DNS Server and also shows all those other DNS Fallbacks. I cannot for the life of me find where those are coming from nor where they are specified. This file seems to be the only place that these are mentioned. If anyone could clear up where these are being injected from, I'll sleep better at night!!

In my case the (commented out) config line "FallbackDNS" in /etc/systemd/resolved.conf contains four entries (IPv4 code9, IPv4 google, IPv6 code9, IPv6 google) and exactly those four are set by default.

I looked this over and while it says bad things, nothing really jumps out as inciting a solution. Not sure if the behavior of the hostname service is an indication of something.

Well - if you look for "station" you'll notice this:

Since both MAC addresses are only 1 apart and both SSIDs are "Raccoon", I suspect either a router hiccup or a 2,4 GHz/5 GHz issue.

Please reboot your router and check if the problem persists.
If yes, try to separate both WiFi frequencies by giving them different SSIDs and connect to one of those SSIDs.
