I have a GL-X750 (on 3.215) which works fine over 4G through its internal modem. However I can’t get it to run it as a repeater for a local wifi service. It connects and logs in to the wifi network but I don’t think it is routing to the correct upstream router:

I don’t understand how or why the first hop goes to 10.128.48.1, instead of to 10.128.63.254.
This behaviour is consistent, either with mwan3 running or not.
I’m including the full ifconfig below. Yes: I think 10.128.63.254 is the correct gateway and I can’t understand how or why anything goes to 10.128.48.1. I suspect it’s something to do with the /20 address space instead of the more common /24. But I cant’ guess why it happens (only?) in this case.
