The SBG900 worked well enough until I purchased a Logitech Revue, which has issues with the SBG900, such as dropping connections which required a reboot of the router, among other things.
After doing my research, I found that the Zoom 5341J was Comcast compatible and capable of connecting to 8 download channels and 4 upload channels, compared to the much more common 4Down x 4Up configuration. Keep in mind that the Zoom 5341(with no J at the end) is a 4x4 configuration.
The Zoom 5341 is a modem only, not having a wireless router embedded like the SBG900, but I already had a Linksys WRT54G router, which I had already pulled out to try and rectify my problems with the Logitech Revue. The SBG900 kept dropping the wired connection to the Linksys though... The Zoom 5350 is compatible with Comcast and has the same specs as the 5341J, but also has a wireless router and 4 wired ports as well. I considered it, but decided to go with seperate pieces for modem and router duty.
The evening that the Zoom 5341J arrived, I installed it in place of the SBG900, and plugged my laptop in. Once it had established a connection, the Comcast device activation page came up in my browser, and I was able to switch the activation from the SBG900 to the Zoom 5341J in minutes, with no need for phone calls to support.
The configuration of the Zoom 5341J is very simple, and I made no changes to the default configuration. I did check the connections, and found that I had 8 download connections and 2 upload connections. It appears that Comcast in my area will only provide 2 upload connections.
I plugged the Linksys WRT54G in and had WiFi a minute later.Read more ›
So I got my Zoom, hooked the cables up, and ventured to the Web. Initially, Comcast's self-service activation had a problem (that the machine could not define) with my unit even though all lights were up correctly. Dreading to stay on the phone listening to elevator music, I opted to "Chat with an online expert." (Via the very modem connection.)
The agent asked me to read the MAC address even though their system should able to identify based on the chatting session, and added this unit to my account. (See the package picture for how to locate it.) Then told me that "I sent it a signal but it cannot receive." The "advice" for me? "Find a replacement device." Really? I had already viewed my unit's status Web page and determined that the device was working perfectly. I insisted to try again. Comcast - or the agent - failed again. Anywhere I browse landed on Comcast's activation page. "Find a replacement device." I gently suggested that the device couldn't possibly be defective because I was able to ping any Internet server (beside the fact that the very device was used in the chat). "I understand. But my advice is for you to find a replacement device.Read more ›
My configuration of Comcast service in this case is 2 times 50 Mb/s download and 10 Mb/s upload speed. This service supposes to supply over 1000 users with Internet access, load balance mode. First line was activated with Zoom modem and everything went well for several days. To the second line I attached Motorola modem; Comcast managed to deactivate Zoom modem on the first line in process, though. Initial test of Motorola showed expected values in download and upload speeds. However, with network connected to it, Motorola download speed didn't reach more than 10 Mb/s download with upload of 2 Mb/s. After 24 hours of 1000 people complaining, Comcast Technician came to check the installation and re-activate Zoom modem. Test of Motorola modem with a single laptop connected didn't show any abnormality: Download and upload speed were at nominal values. Since I couldn't put in place my load balancer yet, I switched the network to the Zoom modem and made 1000 surfers happy again. In a couple of days my load balance configuration should go live, using one Motorola and one Zoom modem. I intend to update this review with the result of Motorola performance in this configuration, for potential buyers interested in the Motorola SB6121.
Well, I decided to buy Comcast Internet service for home and I didn't have dilemma which modem to chose; Zoom it is.Read more ›

Very nice modem. Word of caution though: this modem is not compatible with Comcast Business internet services. For that, you need to purchase either the model 5345 or 5370.Published 13 days ago by mooshoo27

Cheaper by far than renting a modem from comcast. I'm quite happy with the automatic IPv6 support, and the speeds.
Wish it had a better web interface. Read more
