Note that when connecting to the DSL-302G modem via Ethernet port you do not have to install any
drivers or software for the modem. You should be able to access the modem via your WEB browser

If you plugged the USB connection before installing the modem software or if the USB driver was not

1. Leave the modem connected to the USB port. Open Control Panel > [Performance and
Maintenance] > System > [Hardware] > Device Manager.

point next to it. The DSL-302G modem may come up as USB Ethernet Controller. If found,
Uninstall this device by right-clicking on the device and selecting ‘Uninstall’. Once finished, Unplug
the modem from the USB port and reboot your computer.
3. Reinstall the software as shown through points 1.1.1 to 1.1.7 in this guide. If you see a message
about files which can not be found, enter the file location as C:\WINDOWS\SYSTEM

Look under Network Adapters – make sure your Network Card (when using Ethernet) or DSL-
302G modem (when using USB) is installed properly.

Connection is not bridged with another connection. If it is bridged – right-click on it and remove
from Bridge.

Area Connection and click on Properties. Select Internet Protocol TCP/IP and click on Properties.
Tick “Use the following IP” option and specify the following settings:
IP Address: 10.1.1.5
