Replace your old Cable Modem with Motorola Surfboard SB6141 DOCSIS 3.0 Cable Modem


The speed at which our modems connect to the Internet is as important as the speed supported by our Wi-Fi routers. Often, we might concentrate more on the specs supported by Wi-Fi routers, but we may ignore the modem (mostly supplied for free by the Cable Internet provider), that connects behind it. Now that certain ISP’s have started charging a monthly rent for the supposedly ‘free’ cable modem, it might be a good time to think about returning that free modem and upgrading to the latest model that supports higher speeds/better performance. In less than a year, the investment on the new modem will start paying back, as well!

Motorola Surfboard SB6141 DOCSIS 3.0 is the newer model of the very popular, slightly older cable modem – Motorola SB6121. The new model supports 8 channels downstream (throughput levels about 300 Mbps), which is 4 channels higher than older version and supports 4 channels upstream (throughput levels about 100 Mbps). Since it supports more number of bonded channels, the Internet connection is not only faster but more consistent – we get similar (sustained) speeds over a period of time.

As this modem supports DOCSIS 3.0 standard, the speeds are about 8x higher than older modems that support DOCSIS 2.0 standard. Do check the model supported by your cable internet provider and see which standard the modem supports. If it doesn’t support DOCSIS 3.0, it might be worth investing in the newer modem to get higher speeds. Of course, you can also request your cable internet provider to provide a newer modem, if possible.

The Motorola SB6141 modem is just that – A modem. It is not a router and it doesn’t have Wi-Fi capabilities (You can look at the Motoroal SBG6580 modem if you want a built-in router, 4-port switch and Wi-Fi capabilities). Hence, you need to buy a router (either wired or Wi-Fi router) and connect it to the modem in order to enable devices in your network to share/access Internet. Also, one can consider buying the Asus RT-AC66U or Netgear R6300 Wireless Routers that support the latest Wireless AC technology (Gigabit Wi-Fi) for faster Wi-Fi speeds/connectivity.

In the US, you can expect the best performance from Motorola SB6141 in DOCSIS 3.0 approved areas and with cable internet providers like Comcast, Time Warner, Roadrunner, etc. who have approved this modem to work with their service. This is important because, during the initial set-up you need to call your service provider and provide the MAC address serial number to them and they will have to add it manually in their system, for the modem to work. So, it’s better to work with modems that have already been tested and approved by your cable internet provider (you can check this in their website or by calling them).

This modem is small and compact. The black one might fit-in well with any decor. Try to keep your network equipment insider a small network rack attached on the wall, if possible. The modem also supports AES encryption and IPv6.
