I can connect to my router but connection to internet is spotty at best. This includes Roku, Vizio, Google and Apple phones, variety of tablets, computers, printer and alarm system. This started about a week ago. I and my son have called Verizon numerous times and tried all their trouble-shooting steps. Right now, my laptop is connected to the internet but phone is not although it was connected earlier today. Is it time to buy a new router?
