A: AnswerYes, this modem is compatible with major US Cable Internet providers including Xfinity.This question and answer was generated by AI based on customer and product data.- A: AnswerThe 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.

Modem gives you extra/free speed with Comcast
This modem gives you extra speed if you have Comcast, and you get the 150mb tier speed. I'm paying for 150 down and 5 up, but I'm getting an average of 180 down and 6 up. I've tested with multiple speed tests and servers. The slowest I've gotten with this modem is 178 download, and the fastest I've gotten is just over 184. Line quality is perfect and without packet loss. My ping on different servers locally is 4 to 7. Never any errors. The only negative I've found is it runs hot. You will need to place it where it has air all arpund not in a confined place. Also, when we had a big heat wave it got warm enough to lossen the cable in the back. I tightened it back up and it hasn't been a problem since. I highly recommend this modem if you have Comcast 150mb speed. And I also hear that it gives some extra speed on the 105 speed, but I can't varify that. Also got the price match from Amazon. Hope this review helps!

Great modem at a great price!
Great modem at a great price! Important note. I was talking to tech guy at Arris as I am super OCD and I called because I read the user guide and it stated that the top and bottom left lights are green but in real life I was looking right at them and they look white! He explained to me that the two middle blue LEDs were so close and bright the when viewed from the from they appear to make the green LEDs look white and everything was working as it should. That is why I have included two pictures so you know what it really looks like. Also I have tech background and could not get it to work at first but confirmed with Arris and sperate IT GUY that the reason it may not auto set up is because Xfinity Comcast setup is absolutely garbage. You MUST dial in and get a tech support person and give them the Mac ID. Then after the phone call about 10 minutes later everything was working and no issues since.

Setting it up was easy
Setting it up was easy. Just a call to Comcast and voila. Its performance is very good. It does not heat up. I think it was a good decision. The only con was the delay in arriving... it took near a long week; even existing in nearby stores.
