i have a laptop connected to the modem with a cable and my sister has a tablet connected wirelessy, the problem is over 1000 ping in games (any game). i tested it on several pc's and laptop's and the same thing again. she only watches videos and doesnt download anything just like me, the only app thats running is my google and her google. the problem is since the day i got internet and i dont think the tablet is the problem, because a laptop wirelessly connected and my laptop connected with a cable it still laggs and over 1000 ping in games, whats the problem? modem?
