A couple of things to look at,
1. Can confirm that you have link with the switch? (should be an led on
the switch port you plug the linux box into)
2. Recommend you hard code an address on the linux box at first to
eliminate possible problems with DHCP. Select and address that is
unused on your LAN and configure the box with that. You should also
configure the default gateway and include your DNS servers used by the
other systems.
3. On the router how many addresses are allocated for use by DHCP? If
you have used all of them then a new box will not be allocated an
address.
4. Is the hub being used 10Mbit or 100Mbit? You may need to lock down
your NIC to the proper speed and duplex settings.
Once you have manually configured the IP address and other information
you should be able to ping the other machines on your LAN. If that
works then you need to look at the DHCP setup to see what is wrong.
