If I understand the device correctly, it's a bit more than an ADSL
modem or an network card. It's an ADSL router (or modem) on a PCI card
that presents itself to the host as an ethernet card. Think of it as
an ADSL router, ethernet cable, and NIC all rolled into one package.

You can configure the Realtek NIC using the normal network tools of
your distribution, but you need to knwo the IP address of the router
to connect to it and configure the Internet connection.

Apparently this device turned up without any documentation, so we
don't know the IP address.

For that you would need to know the MAC address of the router.
Hopefully printed on the device, but not always.

Other alternatives are nmap, or running arpwatch (or tcpdump) and
flooding a wide range of IP addresses and broadcast ranges and seeing
what responds (assuming that the router has been setup to respond to

Unless you like messing around with networks I suspect contacting
the supplier for the documentation is the easiest thing to do.
