I have a a motorola SB4200 cable modem. The internet goes pretty fast however the download speed is really slow. Are there any things a could do about it?


That modem is too old to use. Most cable systems have upgraded to DOCSIS 2.0. Yours is not. Call your data support line and ask. It will still work, but very poorly and can be intermittent.

Online light blinkin in motorola sb4200


1- Disconnect the power at the back of the modem.
2- Disconnect the internet cable at the back of the modem (the cable from the wall to the modem).
3- Wait at least 2 minutes.
4- Connect the internet cable back.
5- Connect the power cable back.
6- The lights on the front of the modem should start turning on one at a time; the top one first, the second one next...

If the on-line light still blinks, you might want to repeat the steps above after shutting down your computer. Turn on your computer if the on line light is OK (not blinking).

If all fails, call your internet service provider (ISP) to see if the service itself is down for maintenance, or if there is a problem with high-speed internet in your area.

If you have a router, you might want to power it off before trying the steps above. Turn it back on when the on line light is OK.

Usually, I call my neighbor who has the same ISP to see if their internet is down, before I call the ISP company.

Hope that helps.

Sb4200 modem not working


The only time you need software for a Motorola SB4200 is if you are using USB. If you use ethernet then it is simply plug and play, no drivers required.

The USB Drivers are here.

Good Luck.

Hope this helps.

Acitivity light is always off, cannot connect to the internet


Might want to try a new ethernet cable going from your modem to your computer- If that does not fix your problem then I would try connecting through USB.
