These are the errors in the log that cause the router to freeze and not respond for like 30 seconds or so:

Hi,

  1. What firmware version is AX1800?

  2. Is it enabled repeater? If yes, did the router connect the "Multi-APs and same SSID" WiFi through repeater?

  3. These log are normal print. Have you ever connected to USB dongle/ modem, etc., but it will not cause the router to freeze.
    Please check whether the Internet and router are working properly on your PC: ping the [router LAN IP] and ping www.google.com.

  4. Please share the issue syslog with us and let us know your network topology diagram.

  1. Firmware: 4.7.0
  2. No Repeater. wired Ethernet to AX1800 and C7800 modem.
  3. Netgear C7800 Modem > AX1800>PC
  4. Can't post the log too large but here is what i can post: Wed May 14 11:55:30 2025 user.notice AdGuardHome[7689]: 2025/05/14 11:55:30.194046 [error] dnsproxy: 1.0.0.1:53: response received over udp: "exchanging with 1.0.0.1:53 over udp: read udp 192.168.0.14:41178->1.0.0.1:53: i/o timeout"

Also, I have been having problems with connection since update 4.5. I even had an issue that the SQM didn't reload after a reboot. I have rolled back to 4.4.6 and things work great. The speed and the SQM works when you reboot daily.

  1. Checked the syslog you attached, it seems that the network port (LAN2) has down. In v4.7.0 you try SSH to the router, and execute the commands, to observe if this issue reproduce again:
ethtool --set-eee eth2 eee off
ethtool --set-eee eth1 eee off
ethtool --set-eee eth0 eee off
  1. Regarding the plug-in SQM, please try to completely remove this plug-in and reinstall it, and disable the hardware acceleration, to check whether SQM is loaded after the router restarts.

It's probably one of the devices going in and out of sleep mode. Apple TV is the culprit.
