Comcast Internet Speed Tests

I have had comcast connection for internet. Comcast always claimed that I on my high speed plan but my existing wifi router would never give me that much speed. I switched to ubnt router and voila comcast's claim turned out to be true.

Upgraded our internet speed with Comcast to 500mb/s so I needed a DOCSIS 3.1 modem. This modem was reasonably priced and has been very reliable. This modem is connected to a Netgear R7000 router so I have never used it cabled directly to a PC, but on the wired connection of the router speeds have been over 500mb/s, close to 600. Highly recommended if you are looking for a DOCSIS 3.1 cable modem.

My Comcast internet tier was upgraded to 1.2Gbps. I purchased the CM2000 to take advantage of the increased speed. Set up was a breeze with the support of a Comcast agent (to update their records) and then the use of the Xfinity app (to complete the set-up). I am now getting over 1Gpbs download (at the modem) with upload of 40Mbs. Highly recommend this modem. My next step is to upgrade my router to NetGear Nighthawk AXE11000 Tri-Band WiFi 6E Router to improve Wifi coverage and speed.

I have been using the CM1000 for three weeks now, and it has increased my internet speed significantly. I had no issues setting it up with Comcast. I would recommend this product to anyone looking to upgrade their modem.

Recently purchased this modem (CM1000) to take advantage of cable internet provider (Comcast) speed upgrade. I am now getting 180 Mbps download speeds. The CM1000 is fully compatible with Comcast. Purchasing your cable modem pays off in less than a year when you consider the monthly rent for the identical modem through your internet provider.

I got this to replace an ARRIS SURFboard SB6183. Comcast increased my internet speed and advised me to upgrade my modem. This is modem is excellent. Installing on Comcast was horrid. I couldn't get a human on the phone to give them the new MAC address. I have a Linksys EA8300 router. I had to reset the router to get it to work with the modem - bug ugh.

Bought a CM1000 because I upgraded my Comcast Internet service to 1Gbps and Comcast salesman recommended it. It turns out a right decision. I always got a downlink speed 650Mbps and uplink speed 30Mbps.

having used an Arris model previously which, despite the great increase to my Internet speed allowed by the Comcast, the overall speed at my laptop remained minimal. so when i installed my new Nighthawk AC1900, like wow, did i ever see the Net speed increase over 100%!!! the functioning of the unit has been smooth, steady, and most impressive. i am pleased to have made this purchase!

I got this to use with a speed light. The first tests were acceptable.

The modem is compatible with Comcast. It is easy to set up. Internet signal is strong.
