I would suggest that you assign a static IP address. You can do this
with ifconfig:
ifconfig eth0 <address>
Your router should be set for 192.168.1.n where 1 < n < 100. Usually
routers use 100 to 254 for dynamic. The see if it works. Piong either
something on your subnet or external.


What are you talking about?

I just talked him out of using a static. It masks the problem of
no connectivity by letting you THINK you've got connectivity
when you DON'T.

What are *you* talking about? The only way to determine if you have
connectivity is to actually try to connect to something. Failing a DHCP
request attempt tells you no more about the problems of your network
than failing a ping, or an attempt to connect to some server. Only the
raw rookie would think he had connectivity simply because he has an IP,
but forgot it was assigned statically.
In his first post He was convinced he had connectivity because he
had an IP. Turned out he manually assigned it.
When he printed his iwconfig outout it was clear not a single packet
had passed and he had no connectivity at all. Its a hardware
problem.

People who recommend assigning manual IPs on network segments
that have a working dhcp server don't know what they are doing. Its not
a good way to solve problems. Its deceptive, and disruptive to other
users on the subnet. Its unnecessary, and does not solve a cabling
problem, or a dribble connection, or a switch problem.
