After about 4 days on the older firmware I have seen no drops to Starlink.
This means to me that an issue was introduced in the lastest version causing these drops on the WAN port.
Hoping someone from GL is paying attention and can look into this. If there are any logs I can send, I am happy to do so.
There is another thread on here also with the same issue to some other equipment. GL-MT3000 ethernet connection drops & no reconnect - #19 by UserGermany
