Arris TG852G Telephony Docsis 3.0 Gateway Modem

If I were simply evaluating this device's connectivity to the internet, I would give this a 5. I purchased a refurbished one, and I have no complaints about the wireless signal nor the ethernet ports in the back of the device (there are 4 hardline ports, plenty for my small home network). I took one star because this device is huge - nearly the size of my DirecTV DVR. This is not a device you'll place on a corner shelf or some other inconspicuous place and forget about it. I took another star for the headache you'll get if you try to use this device as a self-install with Comcast. Apparently Comcast spends all their money on Brian Urlacher commercials and not training customer service reps how to use drop-down menus. **THIS IS NOT A CABLE MODEM, ACCORDING TO THE INTERNAL SYSTEMS THAT COMCAST USES** If you call their customer service and call this device a cable modem (and if you say nothing, they'll assume this is what you have anyway) whatever person you talk to will say that this is an unsupported device. To avoid this, you need to tell them that this is an EMTA, or voice gateway. Comcast's internal programs have these devices listed under a different menu, and it's not one they look at generally. There is no way for you to know this is what you're purchasing if you use Comcast's website to select your device as their supported devices website simply lists hardware, not what type of hardware it is (they've since added a link to this page with more consumer-friendly devices to purchase). At any rate, I've been using the device for a month and have had no major issues. I have had my wireless signal drop a few times a week, but I don't know whether it's my device or the wireless card in my computer, so I'm not dinging the box for that.

Bought the new (Docsys3) modem because I wanted more thruput and I WAS'NT GOING TO PAY ANOTHER $ 3.95 MONTHLY TO TWC. I had another problem with Time Warner that required a Tech, so I asked him to get me started on the new Telephony Modem. He hooked everything up to the new one so I could return the old modem to TWC and skate the $ 3.95 monthly. Tech then went back to his truck and when he returned to the house he told me " We HAVE to provide you with a modem at no charge because you have telephone service thru the TW cable. If you choose to install the new Modem, TWC still must provide you with a telephone modem, and you will not be charged the $ 3.95 per month, but I (tech Rep) cannot remove the old modem from the house. So I have the new modem hooked up with a signal splitter from the cable to BOTH modems. However, I think this setup is slowing down my download speed because the old modem is Docsys2. What a stupid situation. Anybody out there have any suggestions????

So I have Time Warner and before they had the nerve to charge $3.95 for a modem lease, I wanted to pickup a Docsis 3.0, Gigabit, VOIP gateway modem. The TimeWarner rep gave me this model and TG862G. So I went ahead and got the less expensive one. Word to the wise, although this is a capable eMTA gateway router, Time Warner provisioned the internet, but made me keep the TM602 for Voip services, for what purpose. I have no idea. Had I known this, I may have gotten a Motorola Docsis 3.0 with gigabit.But this one has a 4 port gigabit router, I was playing on the hunch that my old TM602 was bottlenecking my gigabit network. Behold. 20mps down when I was getting at most 10 when I installed the new modem.Docsis 3.0 is a tremendous upgrade from the old Docsis 2.0 modem. The GUI for the Arris is basic, but does the job of supporting the 3 DD-WRT gigabit routers that I have running throughout the house.Also note, this model is considerably bigger than the TM602, but the mounting holes are exactly the same, you just need a bigger footprint. However, the network cables go up from the bottom, whereas in my setup I would have preferred it to come from the top.

Worked for what I needed it for. I was having Comcast (XFinity) installed and I didn't want to continuously pay to "rent" their router ($10 a month).. so I purchased one. It works perfectly. The only problem is that when it arrived, it had zero instructions or set up disk. It also had the "home network name" on the box, but it wasn't what it actually was. The name on the box said something completely different then what it actually is. Im glad Comcast knew what they were doing.. they had to use the routers IP address in order to remote into it and actually get the correct home network name. so, if you aren't able to find the home network name when you hook up your internet, you will need to remote into the device in order to get the correct name. Just google it for instructions.

First off, the unit itself is fine and delivery from the seller was prompt. But there's much more behind the scenes. My comments relate to Comcast/Xfinity and Arris - other providers may be different. I purchased this on Comcast's recommendation - their Customer Service Rep claimed they get the fewest service calls on this unit. When it arrived I was shocked to see that it had NO instructions - clearly this is a single unit taken from a bulk provider order and not intended for retail consumer sale. So I went online to Arris and found the user manual. Once hooked up I called Comcast knowing that they needed to "activate" the unit and connect it to my account. 1 hour later internet was working but telephone and WiFi weren't. Long story short, I spoke with 6 different agents in 4 different departments, finally after nearly 3 hours got the phone and internet up. Used Live Chat on the Arris website for WiFi help since Comcast refused to do anything since it wasn't leased. Arris tells me that "by contract, the service provider must provide all support" and "I don't even know what that unit looks like". While waiting on hold for a Supervisor I finally managed to get into the router, change my network name and password and get my wireless devices to recognize it.So bottom line - Comcast says to call Arris, Arris says to call Comcast. No one will help you - if you can't figure it out on your own you better have a techie friend who can help.
