Question to comcast users who have "up to 50mbps" internet service. What speed (mbps) are you actually getting with this modem (without router)?

My Cox Cable premium service is 100mbs and frequently surpasses that. The DPC3008 has had no problems at these speeds. Hope this helps.

I am not an expert or anything but i'll tell you what I did. I made no adjustments just installed right out of the box and followed the exact instructions. I have 5ghz connections to their connections and the others regular. I have my router upstairs and on a 20mbps plan I get between 24-27 dload with 6-7 upload (speedtest.net) I did notice with either my galaxy s3 or wireless laptop (both 5ghz) I get faster speeds downstairs than in the same room as rhe router. Weird but true. My desktop gets about 26-28 wired. Make sure u don't haveany dead spots in the house that are causing slow speeds. In my house if I go from my family room to my living room like 20 feet away my speeds literally cuts in half. Dload the app for netgear (Wi-Fi analytics) and see which areas of your house give you what speeds. Like I mentioned in my review I had the asus rt-n66u dark knight and saw no improvement over this. Pretty much identical. Good luck and try the app in multiple spots of your residence.

Not sure about Comcast. I use mine with Time Warner Cable internet and have had no problems.

Ummm sounds like technogibberish to me . all cable modems are 2-way. They have to be. Now the question is does it meet the docs is 3.0 standard? Yes it does. You will be able to Get &gt;300mbps down and ~120mbps up.

I have comcast in my house as well, and it works just fine with my internet service! :)

Sorry I don't know. I use the basic Comcast plan but it worked fast and fine on their mid level plan I used to have but don't know the speed.

I usually get 60 -70 MBps . This is much better than a wireless connection. This is an alternative to not having a ethernet connection.

I have a slow cable modem, it's hard to say what "regular" and "higher download speeds" mean to different people, but for my area 12 MBPS is about as slow as it gets. That being said, I run a lot on those 12 megs, so if you had 6 MBPS DSL or something like that you would probably be fine. If you mean a 56k modem, I can't say for sure but I wouldn't bet on any video streaming working out.

I have Comcast and have been happily using the SBG900 modem for years. I'd say whomever you're talking with at Comcast down't know what they're talking about.

Yes. Mine is hooked up to get the internet through a wireless network and it works very well. My computer is relatively far from the wireless modem, so I had to buy a mid-range modem to broadcast far enough for the computer to receive a consistently good signal. When Comcast upgraded the internet speed in this area, the modem was able to keep up with it.

I have comcast 120/11 and I get around 80/10 even though it says its connected at 270mb/s in the power line utility.

I don't know anything about Comcast. Time Warner Cable approves of this modem and it works fine with their service.

No, this modem will support up to 38Mbps. If you have a 50Mbps plan, you will only see up to 38Mbps.

Don't need to reboot. So far, it's been a few months and all signal and speed was stable. I got Comcast Blast and it's 50+ Mbps all the time.

I have it hooked up to our Charter (cable co.) high speed modem which works just fine. The cable internet is really fast but the speed is limited by the router, but its fast enough for our uses.

That is complete b.s. I have been using a TM722g in the San Mateo area for over a year. I have screaming fast internet speeds via Comcast (120mbps) and no monthly equipment fees. From day one it has worked flawlessly and there have been no issues whatsoever.

I am able to view live feeds over 3G on my iPhone. They come in just fine. If you are referring to the Internet speed at your house I would say a few megabits per second is all that is needed. I had uverse which offered a 30 mb/s package (actual speed less than 10) and had no issues. Now I have 50 mb/s with Comcast (about 10-12 actual) and no issues.
