Yes, this sounds like the right thing to do.

I cannot see any trace of any rediscovery attempt in my logs. And as I
said: And restarting MM magically resolved the problem, so I believe a
rediscovery would have to.
But looking closer at the log, I see that I should have done that
earlier instead of just grepping for Modem. There are some other very
interesting messages. The xhci ones look might point to the root cause:

I guess this indicates that the reoo cause is some xhci related problem.
I am not surprised. I am not exactly friends with this controller ;-)
This is the first version of the WRT1900AC, using a PCIe connected EJ168
chip instead of a SoC internal controller:
