Not Compatible with Xfinity but Works Great with AT&T
594461
Back when I had AT&T, this worked great and was easy to install and I used it as the combo modem-router. However, I moved and had to switch to Xfinity and could only use this as a router. Warning - it is not compatible. I spent two days and about two hours with Xfinity and Linksys support trying to figure out how to set it up.

I bought this device, because I wanna replace my Comcast /Xfinity modem that I rent, which cost me 10 bucks per month. So, as others might already find out, this modem was not compatible with Comcast, which meant you would not get the high speed and great quality internet. I used the Comcast modem which gave me 100 mbps, but using this device, i could only hit 50, sometimes even lower than 20 mbps.  I spent hours talking with the representative of Comcast trying to troubleshoot the problem. But eventually I quit. What's worse, the modem did not provide dual band; you  either had 2.4 GHZ or 5 GHZ, but not simultaneously!! So, maybe this device worked for some people but not for me.

Great modem that works wonderful for a friend of mine.  I would have used it myself, but didn't do my homework first to realize that Comcast cable has compatibility issues with it.

I really like it but am new at all this. I am getting apps now to build my library. I did look for the Xfinity app and it stated it is not compatible with my device. I can take it anywhere and watch my shows and movies so I do like it a lot. I am still working on getting it to have all that I want to use and am having fun learning about it and setting it up.

Do you seem to be the only ones that work with Comcast or Xfinity . Because they can't mirroring software on the device or Comcast app will not work. all the other ones that I tried all had that on there and there was no way to get rid of it .

Have had in use for about a month now on Xfinity/Comcast and it works just fine.  Totally reliable and easy to install with Comcast.  I originally purchased the bigger/faster 24x8 version from Costco, but further research determined that I could buy this unit for less than 1/2 the price and it would deliver all the speed possible from my mid-tier Xfinity internet plan, so I returned that one unopened at my local Costco store.

I bought the CTR 350 and then bought a AT&T USB Connect Mercury 885 Sierra Air Card Modem from AT&T.  The CTR 350 does not support the AT&T USB Connect Mercury 885 Sierra Air Card Modem from AT&T at this time.  I contacted Cradlepoint and they said that until their engineering department tests the AT&T USB Connect Mercury 885 Sierra Air Card Modem from AT&T it won't be supported and won't work.  The modem does work in all 3 of my laptops.  The CTR 350 is a good product but until it supports the AT&T USB Connect Mercury 885 Sierra Air card Modem from AT&T I can't use it.

I have AT&T internet service and was told the Frontier modem/router was not going to work.  IT WORKS... it works much better than then 2wire I replaced it for.  I stay online.  My only issue was I had to move the wireless to channel 11.  After that, I was off and running.

Upon connecting this switch, it worked manually. It will not however connect to my internet. It will connect directly to my phone, but apparently 15 feet is too far for this switch to reach my xfinity WiFi. I have the plug in outlets and they work fine.

I bought this phone because I couldn't wait for AT&T to carry it and my 9700 was busted. I tried the 9810 but the keyboard wasn't for me and haven't switched over my biggest gripp is that it only does EDGE on AT&T networks, and not 3G. Now that AT&T will start selling their version of it starting Nov 6th, this is going back.

Pros: great keyboard. A little softer then I would prefer but reminds me of my old Moto Q

Cons: not compatible with 3G or 4G with AT&T otherwise I would give it 5 stars

Works as advertised and got it provisioned by Comcast without issue.  Now, there's a few things to note.  First, although the modem might support 1.4Gbps download, it has a 1Gbps Ethernet port on the back.  So you'll never get more than that even if a cable provider did.  Second, this modem does not include any form of firewall or router, so you'll need to plug this into the Internet port on the back of your access point.

I have this with Time Warner Cable and the wired portion works well.  The Wireless that comes with the unit is not good.  Get a lot of drops and disconnects from all my devices whether it be on 5 or 2.4Ghz.  Better to get the none wireless and add a good AP to it.

I purchased this modem for use with Time Warner Cable 15 Mbps service. The TC-7610-E is NOT COMPATIBLE with the service. I was not aware of this until I contacted TWC to activate the modem.

I used Xfinity network. Got my device last year August. This Netgear device gave me wifi signal on and off. Quite often my phones (and other wifi devices) need to take several minutes to connect to it and they disconnect automatically once a while. The signal from it is not even as robust as the Xfinity hotspot signal nearby. So disappointed because I spend so much money on it. And it doesn't worth it.

Currently this device is not officially supported by TP-Link for Windows 10 usage, only the version 2 will officially work with windows 10 out of the box. That being said, following other reviewers instruction, I was able to hobble together the drivers and got it working. It took a while to get it to work correctly. So if you have windows 10, if your savvy with computers you can make it work, but if you want plug and play, look for the newer versions of this device. Also I was unable to get it to connect to an xfinity wifi hotspot for some reason, so I don't know if this device has issues with captive portals or not, or if it is just a result of the jimmy rigged drivers. Buyer beware.

Other than those issues it works as advertised. I am using this device to supplement my laptops bandwidth (not speed) through channel bonding, and it works very well for load balancing my downloads. I am able to connect to two different wifi networks and channel bond them to distribute the load.

This modem provides fast internet service with my at&t dsl service.  It was somewhat of a hassle trying to set it up.  I followed the directions step by step, contacted at&t for the vpi and vci ranges, and would receive and error message stating duplicate vpi and vci.  If this happens go to summary and find the correct PVC number.  After figuring this out, installation was simple.  All I had to do was contact at&t to get a username and password.
