    Can't connect wirelessly to the SBG900. The ethernet connection works, but every time I try to connect wirelessly I have no internet connectivity. I've changed firewall settings, installed the SBG900 CD, and a slew of other things, but no avail. Ideas? I noticed there is a different MAC address for the wireless access point as there is for the cable modem portion on the SBG900 admin menu. Do I need to tell my cable company to add both to their
    MAC filter for my account?

    I had the same problem and I went to the security setup of the SBG900 in the Motorola website and set my wireless security features. My problem now is that it does not stay connected for long periods of time.

    A couple of days ago the Comcast guy came out, shut everything off, and replace a cable splitter. He left and our hard wired computers still worked but not the wireless ones that run off a Motorola SBG900. WHAT HAPPENED???? Thank You

I had the exact same problem w/ the Motorola SBG900 Modem/Roter combo. I used to be able to connect to my wireless laptop and then all of a sudden it just wouldn't anymore. So I finally called Motorola and one of their techs (who's like a genius or something) walked me through this complicated procedure for resetting the SBG900 at my desktop and, after, even helped me to connect to my wireless laptop. SWEET! Don't waste your time trying these internet solutions. Call Motorola tech support at (877) 466-8646. They're open unitl 1AM Pacific Time.

Good Luck,
Chris from Cali

BJambor you are on the right track i fixed this sort of problem by setting up the mac address for my wireless even though my security settings said it wasn't necessary.

Before i set it up i could connect the network and see the motorola page but wasn't able to access the internet. I set up the Mac address and the internet worked and network connection stopped dropping out.

Definately set up your Mac address if you are having these problems!

I had the same problem. But I changed the "channel" on the online settings and now my computer can find the signal.

Try setting the device to use different wireless channel. It is set to channel 1 by default and most people don't change it, so it gets really overcrowded.

It can be done by logging in to the administration page and first going to Wireless then Network.

Channels 6 and 11 are probably best choices.

If this product came with a cd, make sure that you installed the software and follow instructions. If you did that, type your ip number in your address bar in either FireFox or Internet Explorer and enter your user name and your password, then from there you should be able to configure your router.

Wireless Doesn't Work - No light.

If someone else setup the router for you they may have turned off the wireless. If you can connect via ethernet use the web based configuration utility to turn it back on.

The intial setup is as follows in the manual:

To provide an initial wireless connection to your network and the Internet:
1 Connect the SBG900 to the cable TV system as described in Section A.
2 On each wireless client computer, install the wireless adapter hardware and
driver software according to the manufacturer's instructions.
3 On each wireless client computer, set up a wireless adapter profile to
“connect” the client to the SBG900. The procedure depends on your
wireless adapter and computer operating system.
In your initial profile, use the SBG900 default wireless Network Name
(ESSID) motorola (case-sensitive).
Your computers are connected but not secure.
The default SBG900 settings provide no wireless security. After
your wireless LAN is operational, be sure to enable security as
described in “Setting Up the Wireless LAN” in the SBG900

Can't connect to the internet wirelessly

Well, to avoid confusion, I'd start by doing a factory reset. Insert the straightened end of a paperclip into the reset hole and power up the device to do this. From there, the device should begin broadcasting the default wireless network with the name (SSID) of "Motorola." The DHCP server should also be enabled and if your computer is configured to receive an automatically assigned IP address your wireless network interface should pick up an IP. The security for the "Motorola" network is disabled by default.

Basic troubleshooting from there would be to try to see if you can connect your wireless computer to another wireless network that is know to be working well. Either buy and return another wireless access point or router from a retailer or head to a Starbucks or other establishment that offers free wireless. If the wireless computer is hooking up nicely with the secondary wireless network, you can refocus on the SBG900 as the likely source of the problem.

If after attempting the aforementioned procedures you find that the wireless computer continues to fail to connect to the SBG900 you might have to consider that you have a faulty device. At that point I would consider consulting the manufacturer's documentation.
