Comcast Router Says Not Connected But Have Internet

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.

Connected to Comcast Xfinity Installation went Smooth and connected to a ASUS AC1900 Router is a great combination of range and speed. Glad I picked this Modem.

Delivery was fast with no damage. Comcast support center had internet & Wi-Fi connected without any problems. When handed me off to a different department for phone hookup,again no problem. Start to finish about 45 minutes. I was using a Comcast gateway , which I returned to the Comcast store. Get better performance from internet & Wi-Fi now, but understand my internet needs are modest. I am happy as long as it keeps working.

I would lose internet in my detached garage. I connected 1 ZenWifi to my Comcast modem and the other went to the garage and now I am getting Crazy download speeds everywhere!

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.

I have Comcast internet and I was using a arris modem-router with a lot of connexion problems, slow internet, lost of connexion, etc. I decide to buy the AC1900, it is expensive, but so far it resolved all my internet problems without change my Comcast plan. The setup was very easy and all my devices work much better, even I am using an range extender (also netgear) and works perfect. I highly recommend this product.

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.

The only router on the market that could support Comcast 1gig Internet. Superior wifi and controller built in for any home or small business.

Says it all.

We are comcast customers and we have one room that we could not get comcast wifi reception (even with Comcast wifi pods.) Luckily I had previously wired the room with CAT5e access to a PoE switch that was connected by CAT6 cable to the Comcast modem/router. Adding the Ubiquiti AP was simple and it provides excellent wifi service in the formally wifi-isolated room. The SID for the room is different from the SID broadcast by the Comcast modem/router but this slight inconvenience is worth enduring to get a strong signal.
