May I ask why you need it to be static? The answer could provide two different paths.
The best way to have the "same" IP address is for the client (XO laptop) to be on DHCP, but have the DHCP server (your wireless router) assign the same IP address to your XO's MAC address whenever it requests a "dynamic" IP.
This ensures that you will always get the same IP address when you've connected to this wireless router, but allows the laptop to connect to other wireless routers and get an IP address in their ranges.
If on the other hand you want to have a true "static IP" because your router does not have a DHCP server (very very rare), or for security reasons (which not only is actually more insecure and gives you a false sense of security, but potentially creates an IP conflict), then you can edit the file
- Code: Select all
/etc/sysconfig/network-scripts/ifcfg-eth0 (or ifcfg-wlan0)
The variables in there should tell NetworkManager to not manage this interface, and the static IP value.
