Comcast XFINITY → [CDV] Re: Voice service

Yes you can use a seperate modem for telephony, watch buying used modems for the most part they are stolen/unreturned equiptment from various cable providers, and even if you buy a new eMTA like the arris Tm822g, keep in mind others have had difficulty getting it activated and when they get it activated finally , they often end up having to argue with comcast once the next bill comes because for the most part eMTA modems are not sold retail and comcast starts charging you a rental fee on your own modem, the only retail modem that supports phone that you can buy today is the TG862G that is sold for ~$200 at bestbuy.

Hi Max,
Because a cable company refuses to activate cable modem really only means that the unit is / was associated with an account on the same system. If an item is actually "stolen", there should be a police report somewhere to prove it was reported as stolen.
The fact is that Comcast is semi-notorious for claiming ownership of customer owned equipment and suddenly starting to charge rental fees for this customer owned devices. These instances have been repeatedly reported.
There is about a 90%+ chance that if you upgrade your currently owned cable modem and then sell or give that old unit to a friend or family member on Comcast, they will be told that it cannot be activated and either imply or actually state that the item is "stolen". There are even reports on this forum from folks who moved from one Comcast location to another and find they have the same kind of problem.

Any of the arris eMTAs that end in /CT that are not /CTSIK models that were sold in select bestbuy stores are stolen, the /CT designation means that the modem was sold directly to comcast, and comcast only leases these modems so if you are buying it from someone they either rented it and did not return it or it was stolen from some point in the supply chain.

Thank you guys for the prompt replies. I don't think signal loss will be an issue as I'm only adding about 3' of cable and one splitter to the line. I guess if it is I'll have to address the issue at that time. I don't have any of the equipment to test signal strength. When I used my modem instead of Comcasts leased modem and router combo I actually got the speeds I'm paying for about 119mb peak and a solid 97mb downstream and about 40mb up I believe. I expect to see a little boost when I add my Nighthawk router to the mix as well. You guys got me a bit sketchy now on buying another modem hearing of the issues with Comcast. I'm debating whether or not voice service is really worth the $$ and hassle.

And all of these companies and individuals are selling stolen property and Comcast does nothing about it....interesting???
