NETGEAR CMD31T-100NAS High Speed Cable Modem - DOCSIS 3.0 Ethernet Port DOCSIS 3.0 NETGEAR CMD31T-100NAS High Speed Cable Modem - DOCSIS 3.0 Ethernet Port DOCSIS 3.0

Pros: It's very easy to setup. The whole thing can be up in about 30 minutes including activation from the ISP. I'm using Comcast in PA and it works fine.

I called to Comcast to activate it. It was faster and more efficient to let the modem prompt you to activate it automatically. That only took about 15 minutes.

Cons: Not a whole lot of instructions. Not that I needed it but less savvy users may be scratching their head a bit.

Pros: I hooked up the modem and it connected right into comcast's xfinity internet service and has been working like a charm sicne

Cons: none yet

Other Thoughts: would definitely purchase again

Pros: Just added an older Netgear wireless router and it works with the modem perfectly.

Cons: The modem does get a little warm.

Pros: Works at slower speed, DOCSIS 2.0 speeds, good looks.

Cons: Does NOT work with many ISPs, even brand new Software update is incompatible. Unless your ISP is Comcast, avoid.

Other Thoughts: Upgraded from DOCSIS 2.0 to 3.0 to future proof myself last March but keep running at the same speed. Trying recently to upgrade to 50 MBs DOCSIS 3.0 speed has been a disaster. Netgear admits there is an issue with V501D, they sent me a new V502A under warranty that still does not work with my ISP.

Pros: It self installed and is somewhat faster than the modem it replaced.

Cons: It isn't as fast as I thought it would be. It gets warm.

Other Thoughts: Painless install on the Comcast network in the SF Bay Area.

Pros: Speeds were fast and it got the job done. It's on the approved list of modems for Cox at a cheaper price than they offer.

Cons: I went against my better judgement and bought a Netgear product based on the price. I took a chance and lost. After a couple weeks the unit died. It still powers on, but will not receive upstream or downstream from Cox. I had a Cox tech come onsite which cost me $50 because it wasn't purchased from them, and I had to purchase a working modem from them so I lost a lot of money in the long run. Don't waste your time and money with this, it will not last long.

Pros: It works like a modem should. Owning your own modem cuts paying your ISP any extra money to lease theirs (looking at you Time Warner).

Cons: Took a few calls to get TWC to activate it, but after speaking to a third tech it's up and working.

Other Thoughts: For some reason even after rebooting and resetting my router I had to renew DCHP on the router to get it to talk with the modem.

Pros: Worked great after setup and registering with my isp Cox - Phoenix, AZ

Cons: After about a week my isp issued a system update for the network and the router firmware was then incompatible. Returned for a refund, very disappointing but not a problem with the product itself.

Pros: Plugged it in, connected it to my cable, home LAN network & power...opened a browser window on my PC & automatically got a Comcast activation page. I didn't even have to type in the MAC address, it was detected for me. A 5-minute "upgrade" to the modem (I assume the Comcast firmware update) and I was online. Cable modem stands on a nice, stable base, big, twisty coax cable doesn't make it fall over (like old Linkysys/Cisco modem did). Netgear design is very cool...white, sleek, good-lookin' (did I say that about network hardware!?!?) It matches my Netgear 8-port network switch (which also does not fall over). It arrived fast, and I spent less than 5 minutes opening the box and connecting it. I live in South Florida and the Comcast worked flawlessly. I have 4 channels linked downstream, and 3 upstream.

Cons: I wish it had been free (sigh).

Other Thoughts: I was put off when so many said Comcast did not support this modem. I bought it anyway, because prices are about equal, and I wanted a modem that would look better (I can see it under my computer desk), and my Netgear switch (same design) stands up when my old cable modem (Cisco/Linksys CM100), Vonage box (Motorola VT-2142) and print server (D-Link DP-300U, no stand) do not always. Speeds test the same, but the power comes from the separate channels...I have a lot connected to my LAN: 4 computers, 2 laptops, 3 Netflix devices, Nintendo Wii, 3 wireless N300 AP's...this is gonna be great!

Pros: Worked right out of the box with Comcast. No update needed. I have the extreme 50 plan with Comcast and through this modem I am recieving between 76-78 Megabits down and 30-35 Megabits up.

Cons: The modem will lose signal if you unplug the ethernet cord and plug it back in. This causes you to power cycle the modem everytime you unplug the ethernet cable either on the modem side or the router side. Also this modem did not have any mounting points on the bottom.

Other Thoughts: The modem works as advertised. It is fast and gets the job done. Just keep in mind if you have Comast, you will have to power cycle it anytime you need to disconnect the ehterrnet cord.
