Works better (Wifi signal is a little better, higher throughput speeds, etc) than the modem/router Cox gave me, but my personal issue with this device is that unlike some of their other router/modem combos, this does not have built in MOCA functionality. I purchased it with the intent to set up a MOCA network in my home, but now I have to buy an additional adapter which will run me $50-$70. I like the device, it does it's job very well but I can't five star it when such simple functionality isn't a part of it, when they have the firmware/hardware capability to do so.

I purchased this router/modem after encountering much slower than expected speeds with the Netgear router that I had. The router was supposedly capable of handling up to 320Mbps service... I had 200Mbps through Comcast Xfinity, and I was only getting 50-55 Mbps on WiFi on the 5ghz channel. I spent over an hour troubleshooting with Comcast without making any progress, so I read some reviews on other router options. This one came up as a good option and I decided to give it a shot.Upon installing it, I did have to call Xfinity to get the new router provisioned (activated), and the Comcast rep told me during the setup process that he also had a netgear router and the 50Mbps with the Netgear router wasn't unusual for WiFi even with the 200Mbps Blast package that I had. He said that they don't guarantee any WiFi speeds (only wired/ethernet speeds). This made me less hopeful about the new router I had purchased, but when we got it up and running I ran a speed test and to my surprise found that I was getting almost 240 Mbps!! He was shocked as well, and said that he too would have to go out and buy an Arris router.I have run multiple speed tests since, since I understand that in an apartment building, high internet traffic in your building can significantly affect internet speeds due to channel congestion. The lowest I've ever recorded with the Arris router is 210Mbps and 90% of the time it clocks in at right around 230Mbps, even if I'm streaming video on other devices.Love the product, and given the improved performance, it's very worth spending the extra $ on a quality router.

This duel band WiFi cable box works great with more speed available then I subscribe for. Set up is fairly easy, just call your ISP provider to have them activate it and that is it. I noticed that I could only see the 2.5G band on my laptop as well as the desktop and could not figure out why I was unable to see the 5G band. However I was able to see the 5G band on the other smaller devices eg mobile phone and tablets. Took a while of Google and YouTube searching than I realized that if you laptop or desktop have only a 2.5G built in adapters than you need an adapter capable of receiving both bands. Notably the 801.11ac or one that supports both a and c. Once I got the right duel band adapter the ARRIS SURFboard WiFi cable box delivered that appropriate speeds. We usually have more than 6 devices connected at the same time without any lags or gaps in transmission or rather reception. This is the cable box you need if you are tired of paying the rental fees charged by the cable company. We now need someone to come up with the De-scramblers we're forced to rent from the cable company at ripoff prices, then we can get the monopolies (in our complex) from nickling and dimming us.

I began writing a huge and complex review of this fine cable modem, only to realize why people read reviews is to assist in making a purchase decision.I bought this with the goal of getting the fastest possible Wi-Fi speeds on my Comcast Blast Pro! fiber optic Internet service. With this device, I am averaging about 180 Megabits per second (multiply times 0.125 to get MegaBYTES per second) which is a mighty jump over the past Arris modem I replaced which was yielding 75 Mbps.Now, my laptop is as fast on Wi-Fi as all my high-end gaming PCs which are connected via Gigabyte Ethernet cards and hard wires to this new cable modem. Yup - a wireless device performing as fast as the hard-wired devices on the same network.Tips regarding setup:1-Read the HFC MAC address to your ISP when adding this to your account. DO NOT read them the WAN MAC! Giving the WAN MAC to your ISP will blind them to your device and setup will fail. The HFC Mac address is on the label glued to your modem and on the setup instruction sheet.Tell your ISP this device is relatively 'new' and it may need to be 're-provisioned' a second time to make sure that your ISP succeeds in handing this unit two different dynamic IP protocol addresses. The first (and the one that works right from jump) is the new IPv6 Protocol. The one that was a bit of an issue is the older IPv4 protocol. Your network equipment needs BOTH of these to be assigned to your new cable modem or your Internet won't work properly. Arris 24/7 Tech Support advised me to ask the ISP to rebroadcast the setup signal, and that worked just fine. ALLOW TIME for your device to be recognized on the ISP system and for the firmware to automatically update (nothing you need to do but give it a couple hours). If your unit is not functioning properly 2 hours after ISP sends setup signal, call your ISP back and ask them to re-transmit the setup codes a second time, then allow 2 more hours for it to "be recognized" across the ISP system.Comcast lists this as a "Certified and Approved" device - that's very important - call your ISP pre-purchase and ask if the model you are thinking of will work.This unit has 32 download channels as opposed to many on the market with far fewer. More channels in Docsis 3.0 means faster Internet! AC1750 means both radio frequencies are combined at the same time for max Wi-Fi speed of 1750 Mbps. I won't do a tutorial on MegaBITS per second versus MegaBYTES per second - but the numbers you see on cable modem speeds need to be multiplied by 0.125 to give the MegaBYTES per second.My old Arris cable modem did a great job and was giving 180 Mbps on hard wired but only 75 on Wi-Fi. This new cable modem jumped my Wi-Fi devices up to 180 and I'm thrilled just for that alone. Also when backing up my laptop wirelessly, the backup now completes in just minutes as opposed to several hours when backing up to a Network Attached Storage device (Synology Diskstation).In a nutshell, I took the time to write this in hopes of assuring people who are on the fence that the initial pain of getting the unit activated is far offset by the GREAT IMPROVEMENT I encountered, most especially in Wi-Fi. I recently purchased an ASUS GL753VE gaming laptop from Costco, and I wanted my Wi-Fi to match the performance of my laptop. Done!
