Bests & Worsts Reviews from Amazon

First off I do not recommend buying this device because it has wifi built in, plan on using your own wifi router/access point. I had no plans on using the wifi built into the device and after testing it I reconfirmed my decision. Test results were poor compared to my 2 yr old Dlink N300 router. "see below for details on disabling the Wifi or putting into bridge mode". I have this device installed in a telco closet which houses all of my home wiring to a central location. I use the built in router of this device to broadcast DHCP to my devices on my LAN, it works well for this. It does have 4 GigPorts which was a must for me. I also use 2 Gigabit switches and a Dlink Wireless Router "in Bridge Mode, which disables DHCP" in my setup all located in different parts of the house and the Arris device plays well with all, plug and play. The main reason I purchased this device was to upgrade from a Cisco Docsis 2.0 modem and to return a rented Arris EMTA for voice service that I was being billed for. This device gives me both in one box for simplicity, power savings and greater Internet speeds. I have the Comcast Blast plan and was getting around 25MB to 30MB down/5MB to 7MB up before upgrading, now with Docsis 3.0 I see consistent 50MB to 57MB down/9MB to 12MB up. This to me is a no brainer if you are in the same position to make this change. Lastly, activating this device was very simple or would have been if I reset the device before hand "I bought mine used on Amazon". I had to make a few extra calls to activate it, all went well after I was instructed to hold the rest button in for 20 seconds. I was online with internet and phone 5 minutes later. MY MAJOR ISSUE with activating this device was getting the Wifi turned off. I did not want another wifi signal "SSID" being transmitted in the house and wanted to conserve power and heat from the device. Because this device is a Gateway and touches the Comcast network they have full control over the advanced options of this device. When you login to the router through browser "10.0.0.1" the advanced tab is blocked off for consumer access, this is how you change the wifi and router options such as putting the device into bridge mode. I called at least 7 times for Comcast to turn off the Wifi but NO ONE was able to help do it. I believe this came down to the device not being tide to an outlet for the changes. <<<<<<TIP>>>>>>Before I could get someone to help with that I figured out that if I disconnected the COAX cable from the modem I could login to the Router settings without restrictions in the advanced tab, make my changes and save then reconnect everything. After reconnecting the coax line everything worked perfect and the wifi was turned off. I would recommend advanced users to do this on there own before connecting the coax and contacting Comcast to activate. It will save you time and frustration.
