No gateway address

Your PC needs the IP address of a valid gateway to access remote networks like
the Internet or your remote office. It is configured to get IP addresses
dynamically assigned to it by a DHCP server. The AR100 may be running as a
DHCP server. If this dialog appears, then your PC has been assigned its own IP
address, but has not been given a valid gateway address. This mean that there
is another DHCP server on your LAN in addition to the router you are
configuring, and that it does not supply a valid gateway address.

1. Either
I
Disable the DHCP server at the IP address shown so that the AR100
router can assign the gateway address to your PC, or
I
Add a gateway address to the DHCP server at the IP address shown.
If you are unsure, contact your network administrator.
2. Restart all the devices on your LAN (connected to the PC or the router), and
wait till they have all finished restarting.
3. Exit and rerun the AR100 Access Wizard.

Gateway address already used

Your PC needs the IP address of a valid gateway to access remote networks like
the Internet or your remote office. This PC uses the router as its gateway. The
PC is configured to get its own IP address and the gateway IP address
dynamically assigned by a DHCP server. The AR100 series router may be
running as a DHCP server. When the PC gets a gateway address from the
DHCP server, it assigns it to the AR100.
