Question: Telephony Several mentions have been made that this modem won't do 'telephony'.  Can someone describe what that means?I use a VOIP service for my home phone (using a rented Comcast modem) and use a Google Voice number as a work phone.   Are these the type of 'telephony' that won't work with this modem?Thanks
Document: I was looking to upgrade from the stock Arris Telephony modem from Comcast (xfinity), since I no longer have comcast phone service and would like to stop paying 7$ a month on my modem rental every month I figured I'd buy my own. This is one of the few DOCSIS 3.0 compatible modems that will work with comcast.... (at least according to comcasts compatibility website). I've been using it for 3 weeks and it's significantly enhanced our existing connection.
It is good modem. I get about 45MB Speed from Comcast. Only bad thing about this modem if you are using VOIP phone. It losses the packets. this causes the phone voice to be choppy.This is good modem for internet surfing but not for VOIP.
The modem worked great for when i needed it. I had comcast xfinity internet and the modem worked great. All i had to do was call up comcast and give them the number on the modem and it was working in minutes. Ive had this modem for about 6 months now. Until recently i had no problems with it. Then i switched my service to include phone and now i need a new telephony modem.
Comcast has possibly the worst customer service of any company I have dealt with. I have read several reviews saying this modem doesn't work with comcast, or they have had problem setting it up. Once I was able to get Comcast to ACTUALLY send a tech out (rather than have them not show, then claim they knocked but no one was home...3 times), turns out the incompetent staff was hooked into the wrong cable provider's line. Great modem, no problems.
It required several hours and many phone calls to get my cable company's system to recognize this modem's serials number didn't appear in their list of modems.Moreover, there should be a rule against including either zeros or letter Os in the serial number which, in 4 point type are virtually indistinguishable even with a magnifying glass!
I was being billed the rental charges for 2 months, and long conversations with customer care resulted in them telling that the MAC address was already registered with them, and this was probably stolen & resold.Funnily, after making several more calls and verifying my serial number etc., they were able to add the modem to my service and remove the rental charges. I'm not sure if this is a problem with Comcast or the modem, but I was able to get it solved eventually.
This modem was recommended by Time Warner for customers who preferred to own than to rent a modem. It worked ok for 12 days then the connection started go down intermittently. That lasted 2 days or so. The next evening, it just stopped working. Kaputt. The made-in-China AC adapter was dead. I have the kind of job that requires me to be able to log on from home to do work from time to time, so this was VERY inconvenient.
Bought to use with Comcast in SF however after several hours on the phone with tech support (both Comcast and then Motorola) it was determined that the wrong MAC address was on the product, no way to access the configuration... What kind of QC do you have if you can't catch a MAC address error?
No trouble and no issues. I have had this modem now for over 7 months with no trouble at all. My home network includes 2 PC's and a network wired printer, plus a Roku streaming video box plus several video equipment connections such as my DirecTV all-house HD sharing and the Blu-ray. By-the-way, I use the router to feed my Netgear N600, WNDR3700, wireless router which also works great!
We get a clean signal 6-10 ms ping, no packet loss and 25Mbps down and 4Mbps up, which is great since we have 5 computers, 3 PS3's, 5 PDA (Iphone,Android) phones,5 HD/DVR Directv recievers with whole home DVR hooked up to internet and an ATT Microcell Tower which which works like VOIP for better cell phone coverage.So you can see we are tasking this thing and it just keeps on going.
Answer: OK....I may have found my answer.  Probably the 'telephony' referred to as not working with this modem would be if you have VOIP service through the cable provider.  The cable provider gives you a different modem if you use their VOIP service....I do NOT use the cable VOIP service, I use VoicePulse so I think this modem will be fine as the VoicePulse module just connects to my router.  Probably something like Vonage is similar.So, I am about to take the plunge and order this.
