Nice setup! That’s pretty much exactly what mine looks like - except I use a larger Anker pack and also a wired Ethernet switch off the AR300-M to add wired device(s) to the network if needed. Otherwise, I do the same thing and am hoping the 7730L will be able to operate in the same fashion. It works with my hotspot phone with no issue but that’s pretty standard Android tethering so not a surprise.

Appreciate the responses and the photo. Thank you.
