A while back I was having problems with my cable modem. My home router was also rather old and having a few issues, so I went to Best Buy to see if they had a modem/router combo I could pick up. The only modem/router combos they had were for DSL. So I asked a GeekSquad person walking by if they happened to have any Cable Modem ones tucked away somewhere. He replied that I would ABSOLUTELY be able to use the DSL modem/router combo with my cable connection, as a matter of fact he does just that at home with the same modem/router I was holding in my hand.
"Really?" I replied.
"Yep, I've got it running at home right now on my Time Warner connection".
"So where do you plug in the coax?" I asked...
haha that's great. what did he say after you said that?
