End Of Life Modem
This modem is no longer listed on Comcast compatible device page therefore must be listed as end of lifed. It only had 8 download channels making it obsolete for the future.

Arris SURFboard Modem Differences
You can see the differences in the 3 modems above. The more bonded channels the device has, the stronger the concurrent connections, the higher the capable speed and throughput bandwidth(video explanation). Sure the SB6141 is the cheapest of the modems, but it only has 8 bonded channels and the providers won’t even provision it for over 100Mbps because they know it will have connection issues. Even now Comcast does not list the SB6141 on its list of approved modems, meaning it can only be end of life now.
SB6183 vs SB6190
In pretty much all cases I would recommend the SB6183 and in some cases the SB6190, as it is ready for the next tier of 1 Gigabyte per second speeds that will soon be a normal package. The SB6190 also has double the upload channels making it much faster for uploading.
But what about the similarities? Well, they are all from the same superior family of modems, the Arris Motorola SURFboard series. They are all DOCSIS 3.0, the current standard in cable internet for all major providers. However they have evolved over time and are capable of higher speeds now as you can see. With the increase in download channels, came the increase in download speeds. We have all benefited with newer technologies and faster speeds. The SB6190 has more download and upload channels making it the faster modem. Even if your package can’t handle it now, it will be able to some day as cable companies are constantly upgrading their network infrastructure.
Arris modem similarities
- IPv4 and IPv6 compliant
- Current DOCSIS 3.0 Network
- Simple plug and play installation
- Gigabit ethernet port for router connection
These are cable internet modems that work with Comcast, Time Warner Cable, Cox Communications, Charter and so on. However they are cable only modems and do not work as voice modems for services such as Xfinity Triple Play voice package. In that case you can not purchase these DOCSIC 3.0 modems, they are not telephony EMTA modems. You absolutely must buy a voice modem here.
Modem Comparison Summary
It’s obvious by now that the Arris SB6183 is going to be the modem of choice for most people(myself included). It is capable of handling all speed packages and will reign the champion for a long time. However gig speeds are coming and fast so for many the SB6190 is going to be the modem of choice. It is ready for the next generation of internet speeds.
