The Linksys router interface does not allow for DHCP address reservations, however by default the pool of DHCP addresses is set between 192.168.1.100 to 192.168.1.49.
This means that you can manually assign a static IP address in windows between 192.168.1.2 and 192.168.1.99 that will not be assigned to another device by the routers DHCP server.
Click on the start menu then open the control panel.
Select “View network status and tasks” from the left hand side of the control panel.
Select “Change adapter settings” from the left hand menu.
Right click the connection that you want to assign the static IP address to, then click “Properties”.
The properties window should appear, from here select “Internet Protocol Version 4″ then click “Properties”.
Select “Use the following IP address”.
Enter in your desired IP address that is not in the routers DHCP range i.e. between 192.168.1.2 and 192.168.1.99.
The subnet mask, default gateway & DNS server should be as below:
