Q: What is the difference between the SB6141 & SB6183?
A: The difference between the 6141 and the 6183 is the number of pipelines the Modem will handle. To give you a better idea: http://www.arrisi.com/modems/datasheet/SB6141/SB6141_Data_Sheet.pdf vs http://www.arrisi.com/consumer/_docs/Co-branded_DataSheet_05Jun/SB6183_DataSheet_05Jun.pdf The 6141 is more ideal for people who are not into the higher tier, high speed connections as they will only have 8 pipe lines for Data versus the 6183 with 16. Unless you are really planning on switching over to a higher tier plan, you will not use the full 16 pipes or gain the higher speed as it will be the ISP provider who will make use of the pipeline channels. The flipside, though, even with the lower tier plans, is that with the additional channels, if a few of them are flakey, you have other pipeline channels to fall back on. The important question for you is if you really want to spend the extra money for the additional channels of support, knowing you will not upgrade to a higher tier plan and whether or not your connection to the internet is 'flakey' or fairly stable. If it is fairly stable, go with the 6141, don't spend the money on the 6183. If you plan on going to the higher tier plan or your current plan shows a lot of noisy/error channels and connection must be 'rock solid'... You may want to consider the 6183. Note, the 6183 will not necessarily guarantee the BEST connection status over the 6141, even after what I said. You will want your ISP to look over your cable connection first before seriously looking at a modem as well. I only state the 6183 will probably help with connectivity given the additional channels for the ISP to rely on, but an expensive modem will not be able to overcome a bad cable run.
