Note: dhcpd configuration
Although I've got 802.11n working on my Asus Eee Box, copy big files between Eee Box and my lap-top over WiFi is slow (as my Time Capsule is far away). So I use a cable for file copying, that's gigabit!
But I have to set my lap-top's ethernet to use DHCP in office, to avoid 2 network configurations on my lap-top, I need my Eee Box to act as a dhcpd, that can automatically assign an IP to my lap-top, but don't harm the router/nameserver configurations on my lap-top, and the existing DHCP in the WiFi network.
I aptituded the dhcp3-server package, and look into the default configuration file, got this code:
subnet 192.168.1.0 netmask 255.255.255.0 { range 192.168.1.100 192.168.1.254; }
And it works!
