I just moved into my grandparents house and set my computer up. Now i was at there house a week or 2 ago and i played alot of online videos games. League of legends Counter Strike Ect. I use a wireless adapter to connect to my grandpas Wireless Router. last time i was at his house i was easily able to play with an average of 50 ping. But now it sits at about 96 and jumps in between 150-400 very much. I havnt changed anything on my computer besides downloaded World of Warplanes and Ace of Spades, and he hasnt changed anything with the network since i was last here. Im not sure whats causing this problem, but it is very annoying. Any ideas on whats wrong? Mabey my Wireless adapter is broken or something?
