For Fixed IP Address
The default LAN IP Address of your Router is set at 192.168.1.1. If you
have changed the default LAN IP Address in the ADSL Web Management, you
need to apply the same change to the IP Address of your Ethernet Card.
For Dynamic IP Address
If you have enabled the DHCP server, you will need to change the IP Address
of your Ethernet Card to 'obtain an IP address automatically'.
