DHCP?

How do you configure the IP address (and/or MAC address?) of your 
system? If it is configured by BOOTP/DHCP, it may take so long until 
your interface gets a reply and can configure itself (and the routing 
table) properly.

What do you get, when your print the interface statistics directly after 
network startup?

And try to monitor which broadcasts are transmitted in the 7 seconds!

wkr,
Thomas.
