Reboot. It should acquire new IP.
169 etc means the DHCP server in the router has not given you IP address.
What sort of connection do you have? If it's PPPoE you need to tell the router user name and password.
Is your router setup correctly? when you go to the Administrator tab or Status, does it say Connected and does it show IP address other than 0.0.0.0?
In Comodo, are you allowing trusted network (192.168.1.1/255.255.255.0) or are you blocking it? Are you allowing DNS servers that the router shows?
Whatever WEP or WPA key you put in the Linksys router must be matched by the TCP/IP properties of the wireless adapter on your computer.
