These modems are hard to find. I wish I had seen this at Amazon before purchasing it elsewhere because Amazon has the best price. A few weeks ago I searched for the newer TM822G and was hoping to find that but I guess I missed the TM722G if it was available then, which I don't think it was. I ended up purchasing the Xfinity self installation kit from Best Buy for $149.99 and that included the TM722G plus a few misc. cables, backup battery, installation instructions and user guide. The voicemail user guide booklet is nice to have because it explains all the options, but the information could probably be downloaded from Comcast or picked up at the Comcast service center if you choose to purchase this unit from Amazon.

I initially used a rental Comcast TM702G for about a week before deciding to purchse my own modem, so swapping the modems was easy. All I did was call tech support to provide the proper MAC addresses and we got it up and running in about 30 minutes. Although I have not measured any download speeds yet it seems equally as fast as my previous Motorola DOCSIS 3.0.

The TM722G is a much nicer looking modem compared to the older TM702G, and so far it works great and I'm happy with the purchase. The gigabit Ethernet port is nice because I have it connected to a Buffalo Airstation WZR-D1800H wireless gigabit router. The voice quality is perfect and the voicemail system is much better than the T-Mobile at Home service I previously used.

The modem does not generate much heat so it runs nice and cool, which is good because I'm planning to mount it in my Leviton Structured Media Center I'm setting up to feed CATV, Internet and Phone throughout the house.

We're upgrading our home WAN/LAN by upgrading wireless router for better vid. streaming to all parts of a two-story house, and elected to swap out an earlier Comcast-supplied Arris Touchstone DOCSIS2.0 cable/internet/telephony modem for the newer DOCSIS3.0 Arris Touchstone tm722g modem, just to avoid any potential upstream choke points. Installation was a snap, as long as you follow the directions in the install kit. Make all cable, telephone, and Ethernet connections FIRST, then install the backup battery, and lastly insert the power cord in that order. Also, I declined to use our WAN/LAN router in the install setup, but rather plugged Ethernet cable from modem directly into desktop PC, insuring that when I opened a Net browser, the installation instructions would immediately pop up, and avoiding any "handshake" problems with router. In a matter of a few minutes the modem was up and running perfectly WITHOUT any necessity to contact Comcast Cust. Support. I then powered down the router, patched in the modem, powered up router, and "We have liftoff!" Couldn't be simpler, and great gain in performance: ave. power output is -4dBmV using a three-way splitter at cable entrance box, and download transfer rates using SpeedTest of 35-36 Mb/sec, and upload speeds of 5-6 Mb/sec, ping at 18-19ms. The tm722g is an excellent hi-performance modem for supporting gigabit equipment and digital telephony, and can be self-installed with a minimum of hassle or difficulty. Well-recommended.Arris Tm722g Cable Modem Docsis 3.0

I purchased this modem after reading the reviews on Amazon. The reviews regarding other modems were mixed especially when dealing with Comcast. After I got the Arris 722G modem, I tried working with Comcast in providing the S/N and MAC addresses. After 3 hours later, we finally got everything to work. One thing that would've made this experience better would've been if all the Comcast Technical Support personnel had the same troubleshooting process. After going through three support personnel just for the broadband connection, the important thing to keep in mind is to disconnect all the wireless connection and get the cable modem box and telephone service to work first without having the connections go through wireless router or printer/fax devices. Also, Comcast in our area has an issue of not working with one group to get the broadband and telephone service to work simultaneously. Once the cable modem was working, then I had to contact another department to activate the phone service along with the voice mail service. Hopefully, Comcast streamlines this entire process and can work with a single individual or at least easily transfer the current situation of what has transpired with the other departments so that consumers don't repeat the same information over and over again.

Besides, the issues dealing with Comast, Arris TM722G worked fine and no issues. Initially, I was a bit apprehensive since this was a refurbished box. However, it seems to be working fine for now and can get higher broadband speed with a Docsis 3.0 supported modem. Actually, I can see speed difference compared to my previouse Arris 602 modem. Best of all, I don't need to pay Comcast monthly leasing fee for the modem equipment.

I got this after a series of miscommunications with Comcast. It was what I needed and works great. Setup was easy and it has hummed along ever since I got it.
