I want a modem compatible with performance internet and phone. My provider is Comcast. Is this the right gadget?

my cox internet and my phone work great with this modem but if you are in doubt I would call comcast to see if there would be any conflict with their connection.

We've got Comcast and it's worked great for us. We had their performance package and would get speeds well into the 50 range. We do not have phone though.

To be safe, check with your provider. I'm with Time-Warner and they have an approved list.

call comcast first. They are the worst internet provider but they are the only one that service my area. A couple months after I got this router, I lost connection to my house. Comcast had to come out and run a new line. So, I'm not sure if it was the router but my service is worse than before.

You should be able to go on Comcast's website and imput what type of internet package you have and they list all the modems that are compatible....that's how I came across this modem....there's many choices ..

Although a Time Warner Cable rep assured me this would work for my bundled internet and phone, they said it cannot be used for phone and I would have to keep the TWC issued modem. However, at least I am no longer paying the modem rental fee which was the objective (but illogical to me). As for internet performance, over 50MBs hardwired or wi-fi. Most excellent!

I am in Illinois and Comcast tech. said to buy the Arris TM 722g from Best Buy, but not a single one of those stores within 100 miles has it (what a surprise). That's why I wondered if this one would work. I have the phone and internet pkg.

Good question. Any modem that your Internet Service Provider (or ISP) qualifies to work in unison with its service. Personal preference of some is to lease the ISP modem. Motorola is good FYI.

cannot answer question. I called comcast to get spec. for my router/modem, and the one I purchased would not work. can only suggest that you check with several sources to see what the spec. is for carrier.

You should check with Mediacom, they may have a webpage that lists which modems work with their service. I use mine with Comcast and they have a webpage that lists all the compatible modems.

Go to your Comcast system's website. Find the Q&A; section and look for something like, "Can I use my own modem." If they are like Brighthouse (my provider) they will list all the compatibled modems. Pay special attention to the throughput rate - you must match the modem to your particular rate.

Yes, this works with Comcast (and most US ISPs) for plans up to 38Mbps in speed. ISPs have been pushing customers to upgrade to DOCSIS 3 modems as a means of generating additional profit through sales and lease of equipment. If you're plan is 38Mbps or less in speed, this modem works just fine.

Yes. I bought it for that reason. It's been running on my Xfinity account, here in New Mexico, all year. I get internet, television, and voice over IP bundled. This unit is the modem for Internet and voice over IP. However, be aware that Comcast handles ownership of motives differently in different parts of the country. You may have to fight with him to get the discount taken off of your account.

I've had this modem for a long time and I have Comcast/Xfinity. However, I just looked at the approved device list on the Comcast website (http://mydeviceinfo.comcast.net/) and the SB5120 is no longer listed.

I do not know if it is compatible with Comcast. It is a modem-router in one unit. I do want to add that it quit working after about 2 months and we ended up purchasing the recommended device from AT&T.;

I know the description says for Comcast only, but I purchased this modem in January of 2012 and plugged it in to Charter Cable and it has been rock-solid ever since. I probably should add the caveat that my subscription is for the 60MB speed level, so it's possible that this modem won't work properly with higher speed packages. I believe that the Comcast-only declaration is because this modem doesn't appear in the "approved modems" list for the other ISP's, but that's just my guess.

I use it with my Comcast Dory modem (router, phone, and modem combo) without any problems. Speed seems to be the same more or less but I only do video streaming on this particular PC.

This device has a built in DSL modem and a router. It can be used with either Comcast or with most DSL providers. It is a very good modem/router combo. I have one at my cousin's restaurant and one at her house. I have not had a bit of trouble with either of them since they were installed, and customers hook up to the wi-fi easily.

I don't know for sure. I am using it with Time Warner. They had a list of compatable MODEMS and this was on the list. I would suggest you ask COMCAST. I hope it does as Time Warner is supposed to sell out to COMCAST.

I've had no issues with it. The tech when he installed my service tried to upsell me a newer modem saying this one was too slow. I constantly get 8 Mbps down and 5 up. And yes I have Comcast.

I was able to get it working with Comcast relatively easily. if it doesn't connect for you, don't call the activation line. call the generic tech support number for comcast (1-800-comcast?), get to the internet support and have them connect the modem.The activation department will tell you this modem isn't supported, but the internet support people don't care.If you have a good tech, they should call the activation department to get your phone lines transferred and all should be good.
