Arris TM722G Manual & Product Guides

How to Activate Arris TM722G

Activating your Arris TM722G is the first step you need to take after unboxing your new modem. It’s a fairly simple process, and we recommend setting aside about an hour of your time to ensure you’re able to complete the whole activation.

  1. Plug in your new modem the same as the one it’s replacing. Make sure power cable is plugged in and coaxial cable is screwed in on the back as well. It’s recommended to do this and then wait an hour before calling your provider, if possible, so that your modem can download whatever firmware is needed for the activation.
  2. Next, call your provider and let them know that you’re doing an activation with a self-install of your new modem. They’ll ask you for a few of the numbers on the bottom of the unit and then proceed to get your modem added to your account and service plan.
  3. The call will end after the representative verifies with you that you have an internet connection. You can test this for yourself simply by visiting a few websites.

Your modem is now activated!

How to Reset Arris TM722G

Resetting your Arris TM722G is one of the easiest ways to correct almost all common technical issues that you may experience over the life of your modem. It’s a super handy tool to have in your troubleshooting repertoire and can save you hours on the phone with your provider. Here’s how it’s done:

  1. Plug your modem in to the power supply and wait 2 minutes for it to boot up fully. You’ll know it’s booted fully when the wireless lights come on.
  2. Locate the reset button on the back of the modem. It’ll be on the same side where all the ports are located. Generally reset buttons on this kind of device will just be a tiny hole that may or may not be labeled.
  3. You’ll need a flattened paperclip or pen cartridge to do this next part. Press down and hold the reset button for 30 seconds with your modem still plugged in. You should feel a small dull click when you press in the reset button with your paperclip.
  4. Now wait a few minutes for your modem to reset and reboot itself. You’ll know it’s finished and ready to use when the WiFi lights come back on.

Tip: Still not resetting? Try just holding down for 15 or 20 seconds instead of the full 30. Some firmware versions differ on the number of seconds needed for a reset.

How to Find Your IP Address

This method works on Windows computers and does not require any software to be downloaded. You’ll be using command prompt to find the internal IP address so you can log into your WiFi router or modem router’s settings panel.

  1. Click the start menu in the bottom left of your screen.
  2. In the search bar in your start menu, type in “cmd.exe” and then click on that program when it appears in the search.
  3. When the program opens, you’ll see a black window on your screen with white text.
  4. Type into the program “ipconfig“, then hit Enter. Your window should look like the one shown below. The IP address circled below shows where your internal IP address will be on your command prompt window. Now you can move on to accessing your modem or modem router’s settings admin panel.

    This worked as a good replacement for our original COMCAST modem which was costing us a monthly fee. We’ll break even on this in a short time, so it was a good investment.

    We had problems with getting this to work with our ISP (Comcast). I had contacted Amazon after Comcast told me that the unit belongs to them??? DOCSIS personnel were great! I had emailed a manager several times, was told not to worry about returning the original product until the second unit was working properly.Again, we had problems with Comcast. It seems they hire incompetent people who do not understand English!!! After a technician came to our home, and he contacted Comcast, it was found out that when I gave them the unit number, they couldn’t understand the correct numbers/letters I had given them (and I was on the phone with them for over an hour and a half!).I would definitely order other products from DOCSIS. They are very caring and very customer oriented. They wanted to make sure we were happy with their product and that it was working properly, even before I returned the first unit to them.

    Modem works great! Comcast started charging rental fee for this modem, because they say it’s a stolen one.Comcast requests it back to discontinue rental fee. They go by serial number.

    Why pay a rental fee? Installing this is super easy. The only hassle is that you need your own router if you want wifi and multiple hard wired connections. In fact, the hardest part about the setup was navigating the asinine Comcast phone menu to finally get to an agent. From taking this modem out of the box to writing this review, it’s taken about 45 minutes total. That includes finding my old router, finding an appropriate 12V power cord, and figuring out how to clear up a couple slots on my overused power strip to make room for that aforementioned power cord. Highly recommend this product. Speedtest.net says current speeds are 91.77 down and 6.07 up.

    Seems to be a great product. I’ve used mine for almost 2 years and it has worked well. Good range on the wireless wi-fi, telephone works great, and good speeds via internet. Saved a bundle over rental costs from Comcast by buying my own. Back-up Battery that came with it did not provide much time when power goes out. Bought a 12hr. (more amps) version so now I have telephone and Internet when we loose power.

    I have had cable modems fail and take down my internet before, and I bought this one for a back up to the one I currently use and is furnished with my service. I was going to replace the furnished one since I was paying $7 a month, but my new term or contract service includes the modem in the blanket bill and is not itemized separately! But, I will utilize this modem if I need it. It is a work horse and provides maximum speeds I need with no drop outs. And we use the hell out of the internet with multiple devices connected through a router.

    Very happy with this product, it allowed me to get rid of my Comcast rental modem (ARRIS TG1682G), and stop them from putting out their free Xfinity WIFI through my modem and service. This product is only an internet modem, for internet and telephone without WIFI, you need a separate WIFI router, which is exactly what I wanted. The Comcast rental I replaced was a combo modem-router. I separately purchased and installed the EERO WiFi router system (which is also a fantastic product) to this modem and I now get 250% faster downloads through-out my 5000 sq. ft house and can stream Netflix without pesky drops. This was not possible with the combo WIFI /Internet modem I had been using from Comcast suplemented Apple airport WIFI bridges strategically placed through my house .The ARRIS TM722G package came with instructions that addressed the challenges making this switch from a Comcast modem, I followed them carefully and had no problem setting the new modem up, I did not even need to call Comcast. It took me about 30- 60 minutes to go through the process. I made the switch one month ago, and my phone and internet have been working perfectly. I also bought the “Arris ARCT00830 10/12 Hour Battery” separately to install in my ARRIS TN722G and now have back-up power for phone service (not internet) in power outages.

    Purchased this to get away from Comcast’s $10.00 monthly lease fee. When it arrived, I opened the box and found everything including the instructions on how to connect the router up without having to deal with Comcast. From opening the box to getting it set up took about 10 minutes. So far I am very happy with the router. My connection speeds did increase from about 4.5mbs to a little over 5mbs, this does not sound like much but it is definitely noticeable when downloading large files. The router came with a battery backup in the box, installed with no problem, The battery lasts about 45 minutes before draining. Very happy with my decision to purchase and stop paying the $10.00 monthly lease fee. I will be ahead in about 8 monthly.

    Thought I was getting a unit without wifi built in, but wasn’t the case. However, was able to get the Bridge mode to work on Xfinity. Unit seems to be working fine. Was able to return the one rented from Xfinity. Paired with own Airpot Extreme for much better wifi coverage and strength than the Xfinity unit.

    Don’t let the cable companies hose you every month with their rental fees for a cable modem.Buy one of these, call the cable company to have it activated, then give them back their (probably) 3+ year old box and enjoy the savings.Works flawlessly with Comcast and the built in battery back up is a nice touch should the power ever fail.I highly recommend this for any cable internet subscriber
