I have been using driverguide for 2 years and I'm sick of not having the right drivers for oem 3com modems. I have decided to make it easy on everyone by including the owm number of the modem as well as 3com's product number. If you haven't noticed, 3com doesn't like their customers to be able to identify their modems by anything written on them. To hell with them. Please submit any 3com modem drivers you find in the future and include the serial number as well as the product number. Just run setup or unzip the file into a directory and go into the device manager and specify the location you unziped the file into. Best of luck.
