Windows 7: Internet Lag Spike Problem

Hi, I've been having lag spikes on my computer and Playstation 3 ever since my family got this new netgear router. When I'm on Playstation 3 like in a chat room or playing a game sometimes it doesn't happen but most of the time every about 30-60 seconds I will get a lag spike and it happens on my PC also. I used to have a Linksys router and it never had this problem. But I can't change the router back because of my parents laptop does not connect to it and they think this one is alot better and I totally disagree but anyways. I was wondering if anyone can help me get rid of this problem. It is very frustrating while gaming or even chatting with friends. Btw, im using wireless for my PC and PS3 and the signal is good.

Get a new router then, or explain to your parents about the problem. Go buy another Linksys.

im sure it can be fixed thats a bad suggest i came for help not an obvious fix
