Looking for network tech to fix a hotspot issue (Albuquerque)

Hello.
I am looking for a network specialist to help me fix an issue with some devices on my home network.
I have 3 Baicells 430H radios powered by PoE injectors plugged into a FreedomFI hotspot on my roof.
A few days ago, the freedomfi hotspot stopped appearing on my network.
The lights are still on.
I had someone replace the ethernet cable but it didn't fix the issue.
Tried restarting.
Can't access the dashboard or see the unit from my router.
It was working fine until a few days ago around the time we had someone install the 3rd radio.
I'm currently away overseas and don't have the ability to do anything else remotely, so I'm willing to pay someone to fix it and get it going again ASAP.
Please reach out via email here with your qualifications
