Arris sb8200 t3 t4 timeouts

I don't know what's going on but I constantly have to hard reset my router because my internet keeps dropping service. I'm using my own modem Arris sb8200 . I've attached a link to the event log. I was thinking of going to trade it in for Motorola mb8600 instead. TBH I'm using a FiOS gateway router with wan connected which I've seen several blogs say works fine. What other issues might it be besides just the router?
