Comcast EMTA

Current consensus is that the only customer-owned telephony modem approved by Comcast is the Arris TM722G, which you must purchase from your local Best Buy (if available) that has a Comcast Communications Center/kiosk. About $150 for the modem plus professional installation. Some stores/areas will allow a "self install". Those may supply a kit that looks like this;

Also be advised that some market areas do not allow customer owned eMTA's at all. It's best to call in a see what your market area's policies are.

I know of no good wireless gateways, eMTA or otherwise. When combining modems with router functionality it is pretty much inevitable that the router portion of the mix suffers, both in range, and in user available settings. Comcast's gateways are set with Comcast-specific firmware that is particularly limiting in user options. They are designed to be used one way...set it, and forget it, and that is pretty much it.

As mentioned, the only currently Comcast-approved eMTA (no router functionality) is the Arris TM 722G, which is a decent eMTA, but not the most recent design.

As I've mentioned in other posts, the problem is that buying one is questionable from an economic viewpoint. The 722g is a 3+ year old model, and at the current selling price, plus installation fee, you would have to own it a good 2 years before it paid for itself...in which time you would in effect own a 5 year old eMTA model, making it somewhat behind the curve at the very least.

IMHO, for what you want to accomplish, the better bet is to go ahead and rent your eMTA (as a matter of fact, I do rent Comcast's TM722G) and buy a quality stand-alone router which will afford you the greatest flexibility in setting up your own network.

okay thank you for your replys.

I looked into this and i am just gonna receive a self install kit in the mail. I ordered this:

for the router and i am gonna use a comcast supplied equipment as the modem.

what sucks is i got a VOIP ATA i already use and i asked comcast if i could get SIP information off them and unfortunately they told me its not possible.

IMO, that router seems like a *bottom of the barrel* choice. I would stick with the more well known brands such as Linksys, Netgear, D-Link, Apple, Asus, Buffalo to name some.
