Cable Modem DOCSIS 3.0 (CM500) Compatible with Major Cable Providers Including Xfinity, Cox, for Plans Up to 400 Mbps

So I've had this modem for a few weeks. I used to have a Motorola Surfboard 6141 I believe (going off memory). That modem at times would randomly drop speeds down to 1mb/s maximum for no reason, then throttle back up. I tried to research this and found out it might have been related to the Time Warner Maxx internet package I have (I'm grandfathered into a package that currently doesn't exist). No idea how or why that would matter but it seems to be the reason why my old Surfboard was having problems. So a deal hit and I dropped cash for this modem in hopes I could solve this problem fairly cheaply and so far its working. I haven't noticed any lag, no strange behavior like dropping to 1mb/s speeds, its been consistent and constant fast speeds, even above the stated speeds I should receive. The unit is well ventilated so the concern of heating up is not an issue. It's barely warm to the touch. I think as others have stated, if you put this in a confined space, for example an entertainment center with a glass door, then it'll heat up more than likely because there's no internal fan. But if you provide adequate air circulation then it'll function perfectly from my point of view. Also I wasn't able to successfully hook up the unit and remotely update to Time Warner that I am switching modems (Mac address) so I had to call them. The tech was able to get me going and took about 10 mins. All in all its so far a great intermediate modem.

Netgear CM500 cable modem installation success with Comcast Xfinity! the Netgear CM500 cable modem is a fantastic addition to my home network system for internet access. First, the modem was well packaged, well protected, but easy to open and unwrap. Second, the modem is a beautiful piece of equipment, suitable for upfront placement anywhere in my home or on my matching imaginary living room piano. But more importantly, it was easy to hook up and connect to my existing service provider's network. Comcast Xfinity provides a feature whereby the equipment can be activated and registered using an on-line automatic routine, instead of having to call a service technician. The on-line activation process was successful and worked fast and flawlessly, taking less than two minutes for the whole process. I followed the Netgear manual procedure exactly, and had no difficulties at all. This cable modem is now connected to my home wireless router system, and is a proudmember and contributor to that. Thanks so much to Netgear for creating an elegant, beautiful piece of equipment that works great. My tested download speeds were even faster than my service provider stated they would be. Thanks so much!

The modem arrived early, it worked perfectly after a call to COX, telling me to contact NETGEAR, because it was a modem issue is why it would not connect to my desktop or router. Netgear said it was my router, wrong. The next day a COX tech spent 4 hours at my home. He left telling me that I needed a new router and the internet to my desktop worked on some sites, did not work on other sites at all. For any COX internet customers, once you connect this modem, or any other brand, you HAVE to call the COX Sales department to have it activated, I repeat, call Sales. Also, I use Windows 10, you absolutely have to be logged in as the administrator, That is what I did, my desktop connected to the internet and I then connected the modem to my router and my desktop from the router and the modem has worked perfectly since then. I would buy from the Seller again, without a 2nd thought, I couldn't be any happier with their service. The modem has been an excellent buy and I am happy that I purchased it.

This thing is absolutely horrible. It has no reach. Gotta be right up on it dang near to get connected. I have it running with an even more horrible Tenda router. I even bought a WiFi booster and still no reach. And it’s tiny as heck. Over half the size lesser than my rental modem. I think I wanna keep paying the fees and return this. Update: March 20, 2023: I am changing my review from 1 star to 4 stars. If you need a modem, that you plan on using a router with, this could work. My COX internet service started going in and out. Tried troubleshooting the matter. Cox says they need to charge a technician out to my house. $75 to have someone come fix the very internet I am paying for. So I told them let me think about. ( that’s like paying for a medium steak, getting well done, and they charge you to have a chef come out and remake the very steak you paid for but aren’t getting) so I just Pulled this bad boy out of hiding, blew the dust off and reactivated it. Had a separate Cox rep swap the modem out. She did not try to charge me a tech. She was very nice and fast. And now I’m interneted up again lol. The difference now is, instead of that sorry, sorry excuse of a router by tenda, I’m using the very GREAT Rockspace Mesh 3 box set extender system. And I couldn’t be happier. The thing about this modem is it’s only one output. You could plug your cpu directly, or use a mesh. The mesh is the best bet. In the past, I had to get a larger data plan, (over $100/mo) bc the internet sucked. Cox upsold my plan. But check your equipment before letting ppl charge you. Now, I have a more basic plan, so I’m paying less, and still able to use all my devices just the same. And the netgear has stepped in place of the very heavy duty Panoramic Gateway equipment they give you. And so far, it is working exceptionally . So I actually would recommend this modem, paired with Rockspace Mesh system. And you got yourself some connectivity to knock your socks off. Very impressed. Btw: it was a little difficult to pair, bc I used it prior, so I had to reset both the netgear and Rockspace with their reset buttons to have the names revert back to the original SSID. Then it was simple from there.

I bought this product to pair up with a new Router as I'm upgrading so that I can start connecting up smart lights security cameras music etc so far working perfectly

Where is my cable/internet line? Also kind difficult to set up, anyone want buy this modem really need to add more budget update your modem rather than this. Lessons got
