I Really Need Help

Um I have 2wire modem and it keeps loosing its connection i was thinking of buying a new model or like a lynksis. I have bellsouth fastaccess and if i bought a new modem would it be plug it in and it would work or what. Also would this maybe solve my problem cuase it only happens while playing guild wars.

Well, personaly (playing on the american side)... i have been finding that i've gotten alot of lag morning and mid-day time... i wonder if many other people have been getting this problem (I know my guild was...) and what was wierd, is everyone in my party wasnt lagging at that time, it was just my guild (Issue that i should know of?)

I'm running on a cable modem myself...
