Try click here. Motorola is listed there. Installation is easy if your using XP: It should find the new hardware and either install the driver or prompt you for it. If this doesn't happen, then right-click My Computer - Properties - Hardware tab - Device Manager. Double-click the modem and click Update driver.
Thanks for the info - I have to say, taht if you are having problems connecting, and not getting good speeds, I wiuld recommend you to get another modem. I have repalced two Motorola SM56 modems recently, with these problmes, and the clients communications were transformed - I suspected the modems due to reading elsewhere about the general flakiness of these models.
However, if yoy want to try a driver update first, go to click here you will see there are different drivers for variations on the modem type. I can't tell which s the correct one, without knowing which you've go!
To try and find out, go to Control Panel - Modems - Choose the second tab in the Window that opens - select the modem - and click the More Information button - see if you can tell which from the info you get back.
Installing a new driver takes a number of steps
Download the file and save it on your system.
Uninstall the Modem software using Control panel - Add/Remove programs (the software for these modems seem to be in there normally).
Go to the new driver you have saved - it's probably zipped - and click on the file you saved - and read any readme files.
As you can see from the other links above, you can take rather pot luck with drivers for older products, that's why you may find it simpler and better in the long run to buy a new, inexpensive, modem, complete with drivers on CD.
