Comcast said they will not activate PURCHASED Telephony Modems! (11/21/2013) Has anyone got Comcast to activate one recently?

You should have no problem activating any purchased modem as long as it is not a Comcast equipment, the best way is to purchase it from a reputable retailer. Some scams happen because people sell their rented equipment.I had no problem activating mine a few days ago.

Provisioned it automatically through browser. And, it provisioned both the date side and the telephone side.

Although some Comcast representatives are trained, knowledgeable and consistent with implementing policies, many are also incompetent and half-educated, cheaply paid agents. Most likely you encountered the latter - my reason is that I was able to activate a purchased modem without any problems. Try calling again and it is most likely you will get an opposite response. I have a parallel experience with direct tv. You call today and may experience a rude, argumentative type of customer care rep. Call again the next day and you will hear the most pleasant sounding agent who will do everything to help you.

No problem on installation for me. However, they did try to charge me rent on it the first couple of billing cycles.

Here is how I activated mine. Connect the modem to your coaxial cable from Comcast. Call Comcast (I think I dialed 1-800-XFINITY). There is an option in one of the menus to reset your modem. Use that. You do not even need to speak to a real person. After the command is issued, wait about 2-3 minutes. During this time, Comcast will download their own customized firmware into your modem. Also, the various lights on the modem will turn on and off. Finally, connect your computer to the modem using an Ethernet cable. You can then access the modem using a Web browser to configure it, if needed. I do not recall the modem's IP address, but I think it is 10.0.0.1 (look this up if I am wrong). Also, there is one small problem you may run into. Because this is the same brand of modem that Comcast rents to its customers, they may think it belongs to them and start billing you $7/month for it when it shows up on their network. No big deal. Just call their billing department and explain it to them politely.

Purchased one, it was the TG862G-NA8 variant (the -NA8 variant was flash updated by the Comcast techs and it was operating at the contracted rate, both uploading & downloading), and it was installed 18-Sep-'15 and as of this writing (23-Sep) is working flawlessly. We did not have a need, today, for the voice aspect, but the data, routing & firewall functions were working without issue.No "gotchas" or exceptions -- the BIOS update took a little bit of time (~10 minutes), but the device rebooted a couple of times, inline with my expectations, and we were on-line.

I purchased Zoom Telephonics AC1900 Cable Modem/Router (5363) and I realized all the speed I had been missing with Comcast's Arris TG862G modem/router. I downloaded a 700mb movie in 5mins and 4secs. The range with this router is also incredible. 3 stories away and I'm able to stream in HD and walk around the house/backward with out lagging using Skype. I also have Vonage for phone, and it works perfectly fine with it. This router also allows me to hide my location by using a different ip address. This allows me to stream local NBA games without saying they're "blacked out" for my area.

There are two problems most people run into trying to activate a purchased modem. 1. the modem is not on the compatible list for approved modems -that list is located at mydeviceinfo.comcast.net or 2. Modem was used and associated with another persons account or is actually not theirs to sell and is Comcast's property, which can not be transferred.

This model is working fine for internet, but my phone service does not work. Comcast and I both did a reset - I was told that I need a technician to install? Chat personnel said that I was not sychronized. Has anyone found out how make telephone service work?

Comcast now will honor this modem as of December, if you purchase this device we will activate it.

I have the same services from Comcast and was able to switch to (a used) tm822G which came with a new back up battery. It took me a while to get a well trained support person to undo the previous mistakes of an offshore person who royally screwed up just about everything they could. Once the phone and internet services where switched to the new modem properly I was able to use my own modem but it took several months and two trips to the local Comcast office to correct the billing. Initially I was told by a high level (I think they call them second tier) tech support that Comcast would not be able to switch me to my own modem because they would have to reflash its firmware and once they did, they would own it. So you might hear a lot of official-sounding statements to discourage you from switching to your own modem but going by my experience, it takes a bit of persistence but it's doable.

I know the description says for Comcast only, but I purchased this modem in January of 2012 and plugged it in to Charter Cable and it has been rock-solid ever since. I probably should add the caveat that my subscription is for the 60MB speed level, so it's possible that this modem won't work properly with higher speed packages. I believe that the Comcast-only declaration is because this modem doesn't appear in the "approved modems" list for the other ISP's, but that's just my guess.

I connected my modem I purchased from an Amazon vendor to Comcast and other than confusion over which MAC id to use, had no problem for voice and data. They had to reset a couple of times at start, but all is working well.

ONLY if this specific model is listed on Comcast's Approved Modem List. From what I have read, they have changed their hardware and support networks to specifically exclude "non-approved" modems. Their tech support people may pass you around but their hands are tied.

You can buy them directly from Cisco but you will still have a problem if activating it at least with Comcast/Xfinity

Yes. I bought it for that reason. It's been running on my Xfinity account, here in New Mexico, all year. I get internet, television, and voice over IP bundled. This unit is the modem for Internet and voice over IP. However, be aware that Comcast handles ownership of motives differently in different parts of the country. You may have to fight with him to get the discount taken off of your account.

When I called to connect it, I was told that the modem was already registered with a Comcast account and I couldn't use it. Luckily, I called back and got a different technician who could connect it. So far, the device has been consistent and I haven't had any problems, but I almost wasn't able to use it. It might depend on the technician as to whether or not they'll connect you with service...Just a word of warning when buying used. It would have been nice to know that ahead of time.

I am using this modem since last August. It is working very well with comcast (xfinity) internet service.

Once your modem is connected to the cable, you should be set. But if it isn't recognized (and you'll get an error message if this happens), then you might need to call Comcast. In that case, the tech you talk to should be able to recognize the modem and set it for you.

Comcast installed today (old one died). Phone (landline) works. Built in Wifi weaker than my standalone. Haven't tried the 4 router ports yet.

It's not on Cox's list of approved modems. Most likely they won't even provision a customer bought telephone modem anyways.

Did not work with Comcast here in Georgia. Probably does in some areas. Had to do with ip4 and ip6. They use ip6 here.

It worked for me. I suggest calling Comcast first, however, to confirm that. There is a Comcast website that lists all the acceptable modems. Make sure it shows up. You also have to spend a few minutes on the phone with Comcast to change over. It is not simply switching it out. So, get the info first. It has been too long since I did it to recall all the particulars. Make sure the unit you buy has rechargeable batteries for backup. Hope this helps.

I bought one for the same reason - to save the $8/month to Comcast. After many hours and many calls, a tech (not Comcast!), told me that it would never work properly for all three functions - cable, phone & internet. He said their modems have some firmware that is proprietary but they will delight it. Long story short: pay Comcast the $8 and "Enjoy" it!

Comcast is not a big fan of when you have your modem. Yes, it was compatible, but Comcast after a few weeks stopped working and wanted to charge for technical service help. My advice... run while you still can (from Comcast, that is).

If it wasn't for Comcast you would be able to, but since it is Comcast does not register any refurbished/pre-owned products. Best buy sells the Comcast issued VOiP modems if you need it and they are going to stop doing that because they want you to purchase directly from them.
