This appendix provides solutions to problems that may
occur during the installation and operation of the Router.
Read the descriptions below to help solve your problems.

I need to set a static IP address on a PC.
The Router, by default, assigns an IP address range of
192.168.1.100 to 192.168.1.149 using the DHCP server on
the Router. To set a static IP address, you can only use the
ranges 192.168.1.2 to 192.168.1.99 and 192.168.1.150 to
192.168.1.254. Each PC or network device that uses TCP/IP
must have a unique address to identify itself in a network.
If the IP address is not unique to a network, Windows will
generate an IP conflict error message. You can assign
a static IP address to a PC by performing the following
steps:
