If you're getting Comcast, beware the Arris TG862 modem they may try to give you. That thing sucks ass. Not to mention they'll charge you $7 a month for "renting" it. Best buy your own modem. I got a Motorola SB6121 and it works great. Router/modem combos are generally just headache. Mine went nuts and kept blocking the Xbox 360 from accessing internet due to retard "parental controls." Just make sure whatever modem you end up getting has DOCSIS 3.0 support (practically all newer models have it)
If you were some random spectator I kicked you because you joined at the worst possible time. Don't tell me you've never had that happen before? :8/:
