Let’s assume you want the most future-proof cable modem currently available and that you’re subscribed to a high-speed service plan. If so then the SB6141 is the right choice for you. Why? For starters, It’s approved for use with Comcast, Time Warner and Cox. Not to mention that it has the highest percentage of five-star reviews on Amazon. That alone is a feat within itself.
The Comcast community on dslreports.com has been the extremely vocal about the topic of top modems and consistently concluded that the Motorola Surfboard is the top picked cable modem since 2004! According to Jeff Heynen an analyst at Infonetics, a telecom market research firm, the 6141 is the most popular DOCSIS 3.0 cable modem in terms of units sold.
DOCSIS (Data Over Cable Service Interface Specification) is a standard that is maintained by an industry trade organization called CableLabs. If an ISP has already upgraded its cable modem termination system to DOCSIS 3.0, the Motorola SurfBoard SB6141 can connect at speeds four times faster than the DOCSIS 2.0 standard allows.
Even if an ISP is still on DOCSIS 2.0, the Motorola SB6141 will work, because DOCSIS 3.0 devices are backwards compatible with all previous DOCSIS versions. In fact it might work better than a DOCSIS 2.0 cable modem. Some users report that using a DOCSIS 3.0 cable modem to connect to an ISP that is on DOCSIS 2.0 results in faster data transmission.
In addition to supporting the faster DOCSIS cable modem standard, the Motorola Surfboard supports a Gigabit Ethernet connection between the computer and the cable modem, which is a much faster connection than the Fast Ethernet connection found on a typical DOCSIS 2.0 modem. The Motorola SB6141 supports USB as an alternative method of connecting to a Windows computer. The installation CD has the necessary USB drivers.
If the ISP supports the Advanced Encryption Standard (AES) for data security, the Motorola SB6141 can apply it. Support for SNMP v2 and v3 (Simple Network Management Protocol) allows ISPs to manage the cable modem to encrypt messages and ensure that messages are from a valid source and have not been tampered with. ISPs can use SNMP along with TFTP (Trivial File Transfer Protocol) for remote configuring and monitoring of the Motorola SB6141.
The DOCSIS 3.0 support for IPv6 (Internet Protocol version 6) allows carriers who are running out of IPv4 addresses to provision many more unique IP addresses as the burgeoning world population continues to go online with multiple devices. IPv4 allows for 4,294,967,296 unique IP addresses. By way of contrast, IPv6 supports 340 sextillion unique addresses (34 followed by 36 zeros), which is more than you could possibley ever need.
All in all whether you are an onilne gamer, casual websurfer or just like a reliable internet connection the Motorola SB6141 is a great buy and will be worth the investment for years to come.
