[Ham-Computers] How do I set up "fixed" IP and submask etc on XP, Vista a...

[James B]

The short, long and longest answer is yes you can.

Go to the router information page that shows the "external" ip address
of the router and note the DNS settings (there may be a couple of
"assigned" dns server) also make a note of the Router "internal" IP
address (which you should already know)

You could also run ipconfig /all on the local computer and "note" the
DNS ip addresses that were passed to your local computer.

Turn off the DHCP Server on the router.

Log in to each of your internal computers and go to the network
connections control panel
Open the TCP/IP properties for your NIC Card, Click "Use the following
IP address:".  Enter the IP address you want (If your router IP is
192.168.1.1 the rest need to be 192.168.1.xxx also), and also the
Subnet mask (ususally 255.255.255.0) and Default gateway (which should
be the internal IP address of your router).  Enter the DNS server IP
addresses as noted earlier, you can also put in the Router IP address
as one of the DNS servers.

You should be good to go....
