Comcast said this modem is not supported: Is it true or are they just trying to let me rent their only device?

I have Comcast and have been happily using the SBG900 modem for years. I'd say whomever you're talking with at Comcast down't know what they're talking about.

This modem is for DSL subscribers (and even then AT&T; told me they cannot supported). Cable internet subscribers must get a cable-supported modem.

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 am sorry I cannot help you with this. When we decided to purchase our modem, we bought the same kind that we rented from our cable internet provider. We knew for certain that it would work.

This model is supported by Cox. My physical unit was bad, Netgear support close to useless. Cox support OK but hardware was bad.

Hi, this model is on the Comcast approved equipment list. I'm using Comcast too, but currently I'm experiencing difficult time with this setup. It is not consistent/reliable in the speed for some unknown reason. It can be very fast when it works properly but later the speed will drop almost to a halt. Very frustrating and have called Comcast multiple times, but as of today, the problem still exists.

this is NOT a cable compatible modem. This modem is for DSL connection use only. You need to continue to search for a Cable Compatible modem... it should have a spot in the back for you to screw in your com cast cable line. Possibly refer to Comcast customer support for an updated list of compatible modems. I'd hate to spend the money and it doesn't do what you need.

Yes it is. I have Comcast. Comcast has a list of compatible modems on its site.

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.

No, this modem does not support comcast phone. I am using Magic Jack Plus for my home phone. It works great for me that I don't have to pay monthly phone bill any more. I hope this will help your concern! Young Lo.

No this modem does not support comcast phone service. There is a modem arris on amazon that does.

I bought the Arris TM802G from Amazon because Comcast said I had to have a Doc Sis 3.0 telephony modem. Comcast said they weren't able to support this modem. I told Comcast that I was using it just for phone and cable and they were able to install it over the phone. It should work for Internet as well.

The one that I had purchased did not work with Comcast for me. I was on the phone with them for well over an hour & the bottom line in my application it was a NO GO. It did not work & I bought another brand & it was golden. I bought this brand/model... Arris Tm722g Cable Modem Docsis 3.0However & do not believe & spent that much...

Nope. I had comcast come to marco island and they could not use mine. Said it was prior generation and would not work. I wasted my money on it. Find out from comcast exactly which model is supported. Mine was not.

It worked for me. I suggest calling Comcast first, however, to confirm that. There is a Comcast website that lists all the acceptable modems. Make sure it shows up. You also have to spend a few minutes on the phone with Comcast to change over. It is not simply switching it out. So, get the info first. It has been too long since I did it to recall all the particulars. Make sure the unit you buy has rechargeable batteries for backup. Hope this helps.

I just bought this modem on Amazon and after screwing around on the phone for 3 days with the people at Comcast a Comcast tech was called and he was not able to have it recognized???. I was without phone and Internet for 3 days and let him install one of their modems temporarily. I don't understand this, are they doing this in purpose to rent there stuff??? Comcast is also charging me $39.95 for the tech.
