cable optimization help

[wally]

Okay i have a problem my connection speed goes up and down over short periods of time. When i play counter-strike my ping is below 100 then it all of the sudden skyrockets to 300+, and this is on different servers. When im surfing the web im going to different sites they are loading fast, then all of the sudden pages start loading all slow, slower than 56k modem. Then 2 min later things get back to normal. However, i dont know what to do to fix it. So can someone tell me what i need to do so that i can be helped(i dont know how to post my internet info. speed, etc.)
