Comcast Modem- Arris SURFboard SB6121 in Orland Park

Motorola Arris SURFboard SB6121

Great for the standard levels of internet from Comcast, we needed to upgrade to one of their higher speeds and and so needed to upgrade our modem. THIS WILL NOT WORK IF YOU HAVE IN HOME VOICE WOTH COMCAST (ie a landline)

Save yourself the $5-10/month rental fee if you are currently renting a similar one through Comcast.
