i was unable to use my roku stream stick plus. i have a tplink ac c7 router installed but unable to connect to it. it worked fine before for a few days. the router has specific dos protection setting which identified the time of attack and source of the attack which was wifi udp attack. i walked out the door and immediately spotted an amazon prime van parked a few houses down the same block. i suspect someone in the van with hacking equipment or a neighbor is causing the problems. the license plate starts with 410
if anyone has a similar experience post your reply.
