Summary: Motorola SB4200 ---an excellent cable modem
Review: I read the good and the bad reviews before I bought this modem. Since most of the reviews were above average and being an approved modem for Comcast I decided to give it a try. After hooking it up to my computer(2min.) I called Comcast (Used to be AT+T)and I had it up and running in a few min. .Now I don't have to pay the leasing fee for the Comcast cable modem. I have been using the new cable modem with no problem for a couple of weeks and I am getting the usual fast surfing speeds.The standby feature I like because it disconnects you from the internet but still keeps the modem on and ready. What can I say....its a great product!

Review: I returned the cable company's rent-a-modem 2 hours after unpacking the Motorola. I have dynamic IP svc (unfortunately), so all that was required for setup was plugging it in and rebooting. (A call to the cable service was required to register the unit MAC ID). The DOCSIS 1.0 certification assures you it will work with most any cable provider, and the downloadable upgrade to DOCSIS 1.1 standard is simple. Also, I like the choice of ethernet (RJ14) or USB connectivity and the new "standby" switch. Lastly, the internal transformer means the power plug is a normal size, so it can be plugged in on my desk without hogging the whole powerstrip. Nice modem, nice price!

Summary: Two in a row returned defective
Review: I think you could do better as far as quality goes. Had to return my first modem two weeks after purchase, modem could not hold a connection. The second one stopped working 3 months later, the cable technicians replaced it with a different brand (I forget which) that has worked flawlessly since. My suggestion, buy a different brand or model.

Summary: I would not recommend this modem
Review: I was having trouble accessing certain webpages and I found out that this particular modem has trouble recieving data. This is from an AT&T Technician! They recommended that I wait for a firmware upgrade or get a different modem. As a previous employee that worked with broadband internet, we always had trouble with the Motorola equipment. I would recommend either an RCA, D-Link, or Toshiba. If you are still going with a Motorola make sure it is something different than the SB 4200.

Summary: Great modem!
Review: I was leasing my cable modem and decided to buy one. After shopping around, I bought the Motorola Surfboard SB4200 and have been very pleased. It is faster than my other modem, and the 'disconnect' button is awesome. Before I would unplug my modem but now I simply hit the button and my computer is no longer connected to the internet.

Review: I was renting the Motorola SB3100 and replaced it with this model. Installation was as simple as calling the cable company with the new MAC address, plugging in the cables, and turning on the computer.Now that I will not be paying a monthly modem rental, this modem will pay for itself in just a few months. This modem also has a couple features that the SB3100 did not. It is upgradeable to DOCSIS 1.1 and it has a standby button that allows you to cut your computer from the internet without powering down.

Summary: Motorola SB4200 does work.
Review: Initial attempt to register this cable modem failed due to one reason or another. The MAC address would not update onto the network via the automated online registration. The old MAC address from the previously used cable modem persisted. However, after I cleared out the internet browser's cache and the cookies, shut down the cable modem and the computer, and finally restarted the cable modem and the computer, I was able to proceed with the online registration.
A couple of attempts should be made if unsuccessful.
Anyway this cable modem works fine now.

Summary: Works Great!
Review: Like many others, I was looking to replace my leased modem with my own modem. I purchased the Toshiba PCX1100u based on many reviews here and elsewhere. The modem worked great, but after about 2 hours it would drop out and quit working. Reconfigured it several times with the ISP, but same problem showed up. Returned it and bought the Motorola SB4200. Hooked it up and was off and running within 2 minutes. It has never dropped out and I'm experiencing speeds that are faster than the old leased 3Com modem.
