Your ip address must be on the same subnet as the box that is giving the access and you must specify the ip address of this box as the gateway. You should also state the DNS addresses given in /etc/resolv.conf.
An example of this is if the box to which you must connect for internet access has an address like 192.168.1.10 then you must also have an address in this range eg 192.168.1.20. You specify the gateway as 192.168.1.10

can you tell me how to configure the gateway in terminal because in the settings for the network i put the gateway and everything cuz my ip is 192.168.0.171 and the gateway is 192.168.0.100 and they are all configured but the output of ifconfig doesnt show the gateway!!
thanks

to check the routes, its
route -n

you should have a line beginning with 0.0.0.0

if its not, configure it in your desktop manager or by hand (it won't stay after a reboot):
route add default gw <ip_gateway>

if it still doesn't work, check your DNS (/etc/resolv.conf)

i have a line starting with 0.0.0.0 and it is the ip for the gateway and the dns also everything is fine but i cannot ping anyone on the network? so any more sugestions??

Well it may sound stupid but have you checked the cables/hardware/etc? When you issue the ping command do the lights on the card blink, etc? How about pinging your computer from others?

they do blink the 1st time but then they stop i can only ping myself ad no other, and non users from the network can ping me also!!
