Verify that the network (subnet) address of your PC is different from the
network address of the remote device.

Verify that the cable or DSL modem is connected and functioning.

Ask your ISP if it assigned a hostname to your PC.
If yes, select
Network Configuration > WAN Settings > Ethernet ISP
Settings
and enter that hostname as the ISP account name.

Ask your ISP if it rejects the Ethernet MAC addresses of all but one of
your PCs.
Many broadband ISPs restrict access by allowing traffic from t he MAC address of
only your broadband modem; but some ISPs additionally restrict access to the MAC
address of just a single PC connected to that modem. If this is the case, configure
your firewall to clone or spoof the MAC address from the authorized PC.
