I bought a used MC7354 card and a new LtAP, I can see the card listed under the USB devices, and followed instructions on this page (https://medium.com/@ostrander/assembling-nalte-to-ethernet-gateway-eb252e0dc034). Though I cannot get it functional in PPP or as an LTE device in v7. Just thinking either the MC7354 is dead or I’m doing something wrong, as the R11e-LTE working just fine (but slow speeds with Verizon).
and solution to this - also trying a MC7354 with no luck
