C7 V2 with MR1100 (m1)

[jlmc1978]

Of course I'm new! And I've read over many posts and it appears from what I'm finding that even though I have a router running GoldenOrb (Archer C7 v2)...and the M1 (MR1100, with AT&T sim)...I may still be trying to do something that isn't possible.

I do have internet connectivity...via the C7v2 ---->M1 on WAN. However, the firmware doesn't report a modem being attached.. but, I don't have anything changed in the M1 either (like IP Passthru).

Before I updated to the most recent firmware (or, 3/29/2021)..I was running a version of GoldenOrb that was like..3/20/2020 or so..and connecting the M1 to the USB port of the C7v2 would also allow me to use internet....
Seems that the firmware update did something to that and I couldn't get it to work. Switching back to the WAN of C7 from ethernet port on M1 resumed internet connectivity...

I would like to use this set-up if I can..but I'm thinking I may not be able to do much with the M1 with the C7 as the router..
I have an unlocked 5g hotspot similar to the m1 that I would like to use the same way.... I was trying to set-up the M1 to work so that when I do connect the 5g "mystery' hotspot ...i don't have to make many changes and it just works...

Any ideas or advice?
