New GL iNet GL-AXT1800 user here and I love the little device.
I use the GL-AXT1800 in repeater mode, connecting it via wifi to the router of my ISP.
It all works fine under normal circumstances. Unfortunately the ISP router restarts from time to time and the GL-AXT1800 does not seem to handle that situation correctly. After the ISP router restarted the GL-AXT1800 shows it's still connected to the ISP routers wifi (on the main screen in the admin panel) but also indicates the ISP router has no internet connection, which is wrong. When directly connecting to the ISP router with my phone (or laptop), internet works fine, so it's definitely just the GL-AXT1800 that "thinks" internet is not working.
I can simply fix this by reconnecting to the ISP routers wifi.
I would have expected one of two things:
The obvious one. The GL-AXT1800 should detect this situation and handle it correctly. Maybe just reconnect to the same wifi.
I have more than one wifi configured and accessible. I would have expected the GL-AXT1800 to connect to a different wifi if the main one, the one I mentioned above, is not available. Why did that not happen? The GL-AXT1800 clearly detected that internet is not available.
When the issue occurs, can the device connected to the AXT1800 communicate with the ISP router?
Please run the following commands on your PC and share the results with us:
May need to install the third-party plugin watchcat to monitor and restart the interface.
If the AXT1800 detects that the current Wi-Fi network is available at Layer 2, it will not automatically switch to another Wi-Fi, even if Internet connectivity (Layer 3) is unavailable.
When the issue occurs, can the device connected to the AXT1800 communicate with the ISP router?
No it cannot, the ISP router is on a different subnet. (ISP router 192.168.0., GL-AXT1800 is 192.168.8.) But as I said, the device can communicate with the ISP router and access the internet when the device is connected to the ISP routers wifi.
The problem does not occur right now, I will try to simulate a restart later and see if I can get you more information.

This looks great, sounds exactly like what I need, since a simple manual reconnect to the wifi fixes the problem. I will definitely try it out later. That might fix my issue completely. If it does fix my issue are you still interested in debugging why the problem occurs in the first place?

Understood. Would be a great feature if the router could handle a situation like this. From a users point of view it doesn't matter at which Layer the connection fails I just want it to connect to a working wifi.

I set up watchcat and that fixes my problem! Thanks again for the tip.
If you still want to dig into why this is happening in the first place let me know. Otherwise consider my problem resolved.
If possible, please check whether the tracert results return the LAN IP address of your ISP router.
If they do, the issue may be related to certain quirks in the ISP router’s behavior.
We’ve previously encountered a case where connecting to the ISP router before it established an internet connection caused all outgoing traffic to be dropped until the connection was re-established.
This was the only log entry during the whole procedure:
Fri Oct 31 11:03:07 2025 daemon.info gl-repeater[2679]: (repeater.lua:1738) interface wwan status offline
The webinterface of the GL-AXT1800 shows the repeater wlan as "connected" the whole time for some reason, but it changed to "No internet" when the above log entry appeared.
watchcat was uninstalled during testing.
Following the tracepath logs:
192.168.0.1 is the ISP routers IP
Actual IPs anonymized with xxx
Connected to the ISP router directly:
$ tracepath -n 8.8.8.8

Connected to GL-AXT1800 when the internet is working:

Then I manually restarted the ISP router and waited until the wifi was available again (Checked by connecting directly to it with my notebook)
The GL-AXT1800 still stuck in "wifi has no internet mode".
192.168.0.161 is the IP the repeater interface got from the ISP router.
Connected to GL-AXT1800 when the internet is NOT working:
$ tracepath -n 8.8.8.8
1?: [LOCALHOST] pmtu 1500
1: 192.168.8.1 2.871ms
1: 192.168.8.1 1.714ms
2: 192.168.0.161 501.949ms !H
Resume: pmtu 1500
Based on the traceroute results, it seems that although the AXT1800 is connected to the ISP router via Wi-Fi, IP communication is failing.
This suggests that while the Wi-Fi link is active, IP-related functions such as DHCP or ARP may not be working correctly.
Since Watchcat has partially mitigated the issue, we won’t pursue further investigation at this time.
If you have time to investigate later, please perform the following steps when the issue occurs:
