3 months ago i got my own router to use with fios. it was google Nest router. My connection start dropping alot. The laptop or my iphone doesn't get disconnected from wifi but they can't connect to internet. After 2 mins or so the connection start working again. Then i switched to Netgear Orbi and i had the same issue. Now i switched to Netgear nighthawk and i am experiencing the same issue. Every couple of hours i will lose connection for couple of mins. The wifi signal does not disconnect. I spent hours talking to fios support chat but all they do is reset the ONT and that doesn't fix anything.
Pls help. I really dont' want go back paying 15 dollars month to rent the router or pay the upfront 300.
I was going to suggest replacing the router, but you've already been through several.
Unfortunately, the best suggestion i have (at least temporary), is to actually rent a router (once, to troubleshoot), and put it in front of your own. So ONT -> VZ router -> netgear. You don't need to use the wi-fi on the VZ one, the point is to eliminate potential causes.
