Customer Reviews

The Only Modem to Own
The SURFboard SB5120 is the only modem that I would want to own. My download speeds are over 20 Mbps, even though the cable provider claims to deliver only 6 Mbps. The features include a standby mode to isolate my LAN from the Internet when we don't need connectivity, and browser access to the modem provides information on everything that you would want to know about the current status, signal levels, configuration, and recent history. My order through Amazon was delivered by the vendor much faster than they had promised, and it's been up and running continuously since the day that I booted it up and got it registered with the ISP.

Better to buy after-market
I'm a Mac user and I got to say this product is sweet. Once I got it, I unpacked it, hooked it all up and I was good to go.

The one thing I have to say is that when you use this in tandem with an Airport Base Station, you have to remember to "Renew DHCP Lease" (Preferences>Network>TCP/IP) when you first hookup the modem and after you use the "Standby" switch on the modem to refresh the network to the correct IP address.

Great Speed Boost
Easy set up with Comcast. Called tech support with serial number and MAC number with fast set up. Speed Boost from 2.4 Mbps to 4.+. Downloads of videos and large files much faster.
