lte interface appears/disappears

Wed Nov 17, 2021 6:29 am

I recently bought a wAP R ac and installed an mc7455. When I sign into RouterOS the lte interface seems to being appearing and disappearing every few seconds. I've reset the wap a few times, upgraded OS, and did a firmware update on modem none of which has had any effect.

I'm pretty new to RouterOS so troubleshooting this has been a little difficult but here's the current state of the device. Any help would be appreciated.

Did you need to isolate the USB pins? I have the MC7455 but I am not seeing the LTE interface show up, taped pins or not.
