For the past 2 and a half years I have been struggling to play games like Fortnite and Valorant due to inputs not registering. I have had Xfinity come to my house twice, the first time they replaced my modem and a cable going out to the street underground,(I believe it may be a coax cable going to the pedestal), and the second time they replaced the coax cables behind my modem but I still had the same issue. Recently I've noticed on valorant (which has 128 tick rate servers) that my packet send rate will drop from 128 to 87-92 and that's when I will have issues like bullets not registering. I have the feeling its some wires in the pedestal because last time I was told that it could be one of the problems left if I'm still experiencing the issue. But I am not the expert here so is there anything else that could be causing low packet send rate? I want to call Xfinity again but I have no real proof of this issue because they did not see it when they were here. Also my Out Packet Size Average is changing a lot whilst playing, peaking at 200 but dropping to 90 at times.
