ever since i had comcast cable installed i've been using a router to share. its a linksys one. well i've been experiencing times where my cable is completely inactive and times where it slows down ALOT. like my ping on wc3 and d2 is around 1500. then it'll go back to normal in about 30 seconds. and stay that way for about 10 minutes experiencing minor lag spikes (300-900 ping randomly) when i run fine i am usually around 40 ping and dl at 380 kb/s. but i need to figure out why i'm getting these moments of latency. HELP PLZ!!!
