Motorola SB6121

details: SURFboard DOCSIS 3.0 Cable Modem
hardware type: Cable Modem
date added: 2010.08.08
updated: 2013.02.19
Utilizing the power of DOCSIS 3.0, the SB6121 enables channel bonding of up to four downstream channels and four upstream channels, which allows an operator to offer their customers advanced multimedia services with data rates of over 100 Mbps in each direction.

The SB6121 features a 10/100/1000Base-T Ethernet (RJ-45) port, as well as intuitive, easy-to-read front-panel operational status LEDs. Operators can optionally activate dual colored LEDs for their customer to have visual verification of bonded channels and GigE link use.

This modem supports IPv4 and IPv6 to expand network addressing capabilities and uses AES traffic encryption.

As part of Motorola DOCSIS 3.0 Ultra-Broadband family of products, the SB6121 includes an enhanced tuner that supports up to a 1 GHz downstream input, which allows operators to increase the frequency spectrum for deployment of new high-value services, such as bandwidth on-demand, commercial services, interactive gaming, and IPTV, to their customers.

Can I say I hate it when someone reviews a modem badly because they can't find it? That doesn't help the rest of us decide whether or not to buy it at all.

I have mixed reviews, myself. One friend has had great speed, 100% uptime, no problems for over a year. The other had theirs die around 9 months post-purchase.

I am very happy with it. I bought mine at Best Buy. I am on Cox and I am getting over 100 mb down. Unfortunately they squeeze the up and I am stuck at 5 mb up. No problems so far.

DHCP very unreliable and advanced configuration not available. DO NOT BUY this modem if you need to define DHCP reservations. Attempted to use with a D-Link switch and the DHCP (which is limited to 32 addresses for some resason) would only assign one.
