This is not a router. This is only for phone use thru Xfinity. For internet you will need either a router(wireless) or another modem for wired.

I am using this router with Xfinity and it works perfectly. It is also a for Xfinity phone. It does not require a battery, but if you lose power the modem will shut down and it have to start up again.

This is a modem. I also have purchased a Router. I have xfinity cable, internet and phone.

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.

This does not have a built in modem, the only advice I can give you for finding a built in Modem/Router is to look for a Router built for Gaming, they are always the best as online gaming requires large amounts of data flow, out and in. Myself personally, I would never combine the two. Reason, because if one goes out, they both go out. At least if the router quits working you can still Ethernet into the modem and get online.

Not true. Comcast installed mine. It was a replacement for one of theirs. I ordered the exact modem that Comcast had sipplied.

No you need the modem that Comcast provides, it's a lot bigger with a different config. This one quit after a couple of months use and they would not refund my money just offered another junk one like it.

I am using the exact same modem and I have xfinity internet service. I have no issues at all. Works perfect. Price compare with costco before you buy it.

It is on the comcast list of approved modems. However if you do not subscribe to their phone service you may have some complications getting it installed. I do not have the phone service and the comcast technician who came out to set up my service had problems getting it set up when he call it in to HQ. He was refered back and forth between the internet and phone deparments. Eventually he had to go higher up and do what they call a Grand Slam (a manual install). They got my modem registred after about 30 minutes of getting kicked around. The modem is great and works fine. Comes with it's own battery backup. It is on the comcast list of approved modems.

Sorry for the late reply. This modem will not get you wifi (only a wired Ethernet connection to your computer). You will need to buy a separate router for this. You can buy a combination cable modem and wifi. There are several on the approved Comcast list. I elected to have two separate units. First, if I leave comcast, I can still use my router. Second, I purchased a router with other capabilities including a print server, network storage, cloud capabilities and a DNLA server (media server). Basically, I wanted to build a home network. There are several good routers out there depending what you want. Sorry for the late reply. This modem will not get you wifi (only a wired Ethernet connection to your computer).

That is complete b.s. I have been using a TM722g in the San Mateo area for over a year. I have screaming fast internet speeds via Comcast (120mbps) and no monthly equipment fees. From day one it has worked flawlessly and there have been no issues whatsoever.

No, this is a DSL modem, not a cable modem. It would work as a wireless router for Comcast if you have a separate Cable modem, however it will not work as both for cable.

You should double check with Comcast to ensure that you can use this product with your specific plan, but in general, yes! -- this router is designed to replace an existing cable modem or cable modem/router combination.

Yes, you would also need the modem. The internet provider I am currently using provided the modem, but I needed to purchase the router - so it is not "all in one".

Here is what I found out having just bought one (10/30/14). I was able to go on-line to Comcast after connecting the modem to the cable and a network cable directly to a notebook computer.The modem provisioned without any issues.The phone service work fine to.Here is the hitch...While there are no problems with the modem and it shows up on Comcast's OK modem list I found out the modem is still undergoing testing and not fully supported yet. This means you should be able to get standard internet speeds but if you have the higher speed blast service it will only transfer at standard speeds. They told me this should be fixed within a month... we will see ;) Here is what I found out having just bought one (10/30/14).

It is a combination modem+router. I use it with my phone line. I don't know what Comcast is so I don't know if it works with it.

I've had no issues with it. The tech when he installed my service tried to upsell me a newer modem saying this one was too slow. I constantly get 8 Mbps down and 5 up. And yes I have Comcast.

I have this DSL modem/router. It is for phone internet (internet through the phone company) and not cable router (through cable company). I had trouble setting it up... come to find out it was the phone company's issue... they connected my internet to a second line! Other than that... the device has worked spectacularly. No issues!

My last response was not complete. It does work with Comcast, but it does need a modem also. D
