1) Hardware setup
Plug-in your reliance modem into any usb port and start up your computer (or reboot into Kubuntu if it was running when you plugged it in).
Ensure that you see the flashing light on the reliance modem which indicates that the modem at least the usb port you selected is not disabled and that it has range.
2) Identifying modem device
The default installation of Kubuntu Hardy already has the neccessary drivers for Reliance Netconnect EC325. All that needs to be done is to find out the device name that the OS uses to refer to the modem. Usually this is something like ttyUSB0.
A simple way to find out is to look in the OS bootup logs Use the following command at the command prompt which filters out to only the few lines mentioning modem / USB:
dmesg | grep modem | grep USB

3) KPP Setup
