Question: Does this modem have a telephone connection?  Our phone service is through Comcast, and some modems can't accommodate that.
Document: I gave it a five star but I never tried to use it on Comcast because it did not have a connection  to plug my phone into. I am sure it works okay but not having that phone connection on it gave me cause to return it.
The (second) Comcast installer convinced me that this modem is not compatible with Comcast in Houston. He said the he had personally been through the problem with Comcast himself, that he had purchased his own modem for $150 -- one that was listed by Comcast as compatible with Comcast -- only to be told that not all modems are compatible with service in all areas.
The modem would not be stable. It would loose connection from Comcast all the time. Not sure why that model would not work well with Comcast cable. The technician told me that I should of rented one from Comcast since they offered technical service with theirs and not with one you buy on your own. Which to me sounded very strange. Like he was trying to get me to rent one from them, which would add $5-$8 to my monthly bill.
I was having issues with my 3 1/2 year old Zoom modem cutting out and losing connection, despite nearly constant resetting. Decided try the ZyXEL because the the reviews were pretty good.The ZyXEL did not auto-connect so I telephoned Comcast for connection. It took about 15 minutes from the time I plugged in the modem until Comcast had me connected for service. This was the easiest modem install I have ever worked on. Comcast was able to connect on the first try.
The modem is a great value, it was fairly easy to set up and has great speed.I have Comcast internet service, and called the customer service center to help activate the modem and account. They walked me through the process, it took maybe 20 minutes as the ISP & modem signal processing went back & forth.Great purchase, much cheaper than other modems listed as Comcast compatible, and now I save the fee to &#34;lease&#34; the modem from Comcast.
3 AM called in expecting automated support. I had phone service, so I had to keep old and new modem. Phone service worked on old modem, data service turned off of old modem. Script on new modem kept prompting me to call for automated provisioning. When I called back at 4 AM, automated service wanted to give me instructions to reset modem, which I already did 3 times.
NO  TIME WARNER CABLE DO NOT BOTHER TO BUY YOUR OWN MODEM IT WILL NOT BE WORTH IT IN THE BIG PICTURE IT IS JUST A SCAM THERE REALY IS NOT MODEM THAT IS NOT A PAIN IN THE A$@=//! To hook up .any how none of the modems on there list have phone jack s. So you need another modem any how net gear support stinks  no support from net gear it was sold as new it was more then two years old and net gear lost my business .
It was my second try, with two different units. The first installer told a much less compelling story, that "The activation team has no information on this model", despite the fact that I had chosen it from the list on this Comcast webpage:[...]So I didn't believe the first guy, and after he left tried to deal with Comcast support on the phone, who told me they could talk to the modem but something wasn't working, and that the unit was defective.
This was a modem that was on the Comcast upgrade list. Shipping was fast. Product is awesome! Easy set up and connection. Just make sure to call Comcast to let them know you've upgraded because they have to upgrade in their system.
I have Comcast and this modem, although approved by Comcast, did not work. A tech came out a day later and expressed his displeasure with this unit. &#34;It will struggle with connection and overheat.&#34; Bought the Motorola Surf Board instead.
Answer: no phone connection. Only data.
