Can any one please look at this data from ping plotter and just get me pointed in the right direction. Have been having really bad lag spikes while gaming in the evenings/night. My speeds and all are staying mostly normal with the occasional drop, but nothing you would notice while just browsing or netflixing. Upgraded to 500/30 from mediacom a few months ago.Bought new hard ware to go with it, asus ax-88u router and arris sb8200 modem. Worked great until a few weeks ago when some bad storms rolled through. Have had a new line dropped to my house, new line from box to modem, new ethernet cables etc... Mediacoms trouble shooting says there is signal issues from my modem, but every time a tech comes and checks it, he says signal levels are fine, and says the online trouble shooting says that because it is my own modem. Im not totally dumb when it comes to networking and general trouble shooting and testing, but new to the pingplotter stuff. Any help greatly appreciated.
