Verizon business FIOS internet signal fades in and out and then runs fine for weeks, why?

Verizon can't find any problem. suggested our Sonicwall TZ215 might be the issue. My technician says no, Sonicwall is good. Happened one month ago too, and lasted for a day and a half, and then ran fine without any issues for a month, and Yesterday our internet faded in and out (on/off) all day long, and today started again. Any ideas?

    When the internet fades out, are you able to connect to the firewalls management interface via x0 LAN interface? This is to see if all traffic flowing in and out of the firewall interfaces stop, or if its just the WAN interface.

    I would suggest taking an export of the TSR and checking the CPU states as well as the FPA pool for any error or warning threshold hits.
