I’m using a GL-X3000 (Spitz AX) for my primary internet at the moment using its Cell modem, which has worked fairly well so far.
However there have been occasional dropouts so I figured I’d use the multi-wan failover and a cheap sim in a spare phone to tether as a backup connection (on a different network ofc).
This… Sort of works, but not really how I thought it would?
As in each connection individually works fine - I can have either only the built in modem enabled or only the tethering enabled and it works fine - But, when I enable both so that they are both connected and it should fail over from the built in modem as necessary, I stop getting DNS service from the router for some reason.
The built in internet status check says both connections are still working and I can even ping IP addresses from devices on the network, but DNS just seems to drop dead. I can even run the Adguard home app and click to test the upstream DNS a second before I plug in the tethering device -works fine.
As soon as the tethering device is plugged in and says its connected, try again and it says it can’t reach upstream DNS.
I’ve tried using different USB cables, different phones, different sim cards in the phones, manually setting encryped/unencryped DNS, using adguard or not, just setting the router to automatic DNS, same issue each time.
Any suggestions? The automatic WAN failover was one of the main reasons I got this router and at the moment I can’t really use it how its intended, so any advice would be helpful.
