I recently purchased a new cablemodem because my old old constantly lost it's connection whenever I attempted to download large files (100+megs).
I bought a zoom brand modem that was compatible with my ISP (comcast) and I figured that if I just plugged it in everything would magically work.
I found out that I cannot even connect to the internet even though 'network settings' inside system preferences shows a working IP address.
do i have to configure anything with the new cable modem in order for it to work? i plugged in my old cablemodem and everything was working fine! (except big downloads of course)
