Replaced an old Comcast router, and bought my own. Comcast still updates the firmware, but the UI/configuration page is factory.

My NETGEAR Nighthawk AC1900 WiFi Cable Modem Router Voice is an exceptional product. I recently downloaded the Nighthawk app, which enables me to reboot my modem and avoid any delays. This router is fast and efficient. It is Comcast compatible to eliminate the need to rent additional equipment. This is definitely a good product to purchase.

Can't use phone service

This was an upgrade from a rented ARRIS TG1682G. First, you save $11 a month for not renting the ARRIS. We have the Triple Play with Blast 250mbps internet and noticed an immediate performance increase.

The setup is easy, plug it into the outlet, hook up your cable line and use the provided ethernet cable and connect to a computer. Make sure your old unit is not hooked up. Once the arrows and the earth internet symbol are solid, open up a browser and log into the gateway. It will confirm you have an internet connection after you set it up and Comcast will open a website in the browser to set up your new connection. All they needed was my user name and password, the rest was automatic, they filled in the serial number and built the connection automatically. I used chat to confirm they could see the new unit and it was ready for use.

You are able to set up a 2.4Ghz and 5Ghz network, set both up, the 2.4 is good for older equipment or printers etc, the 5Ghz should work with everything else. I was able to confirm that 24 down channels and 4 up channels were set up with my ISP. Huge improvement and we have 12-18 devices constantly using internet.

The ARRIS would get 80-120 mbps with WiFi and up to 200 mbps with a direct connection, this was with streaming multiple HD/4K programs, downloading at 10 Mb/s and gaming at the same time, the problem was dropping constant connections and losing internet multiple times daily.

The Netgear would get 200-250 mbps on WiFi (up to 30 MB/s download) and 300-350 mbps with ethernet direct connection doing the same tasks. The Netgear has a far better processor, Broadcom chips that do not drop internet connections and the extra lanes of traffic help with heavy use. Plus, it is upgradable to nearly 1 gbps connections and has a nice range increase over the old unit, about 1.5 to 2 times the range.

Save yourself the hassle and upgrade if Comcast internet is not providing what you pay for, Netgear is usually solid but they will sometimes have lemon units so get the insurance just in case.

TLDR: Reliable, easy to set up, more powerful processing, great for multiple devices at once, decent speed increase, faster/snappier internet, increased range, cheaper monthly bill and works with Comcast XFINITY internet and VOIP.

Until 1 week ago when the phone portion failed. Found out today after waiting days to get tech support that the phone op has failed. Dials, connects, shuts down.
Correction: Defective splitter was the problem. Phone and WiFi working perfectly. WiFi is strong, very much stronger than the Comcast/Xfinity routers. Good move to change to the NetGear router from Comcast unit. Move the unit into the house from the shop, no longer need extenders. Yay!
