Sorry to hear about the problems. We've been pretty much problem free. Been using since last year. I've got both ONT and router supplied by Fidium ... ADTRAN's.
A quick look online does indicate consumer issues;
Consumer-reported problems with Fidium Fiber's ONT (Optical Network Terminal) and routers/gateways (commonly Adtran 854-series or earlier models like Zyxel) center on reliability after power events, connection stability, and hardware limitations
10G Ethernet port failures
Failure to recover after power outages or storms
WiFi Complications with using your own router — Switching to a personal router (bypassing Fidium's) often causes daily connection instability, double NAT issues, port-forwarding problems (e.g., IP cameras inaccessible remotely), or DNS-related errors. Some users must reboot frequently or switch back to Fidium's hardware for stability and performance limitations
The most common issues consumers describe with Fidium ONTs and routers include hardware unreliability (ONT ports failing, connection dropouts), router quality problems, difficulty integrating third-party routers without MAC address workarounds, frequent outages or intermittent service, and poor support when problems occur.
