I have two computers that can not access internet, or the

High Speed Internet, and in the Details section it states
that it is enabled and this:

IP Address:
169.254.x.y
Subnet Mask: 255.255.0.0
Automatic Private Address

What is this Automatic Private Address, and how do I get
rid of it? My other computer says 'Assigned by DHCP' and
it works fine. How do I change this one back to DCHP, so
it will also work.

Describe your LAN cabling a bit, and how you connect to the web:
do you have a simple (non-routing) hub or a router? Do both PCs
connect to downlink ports on the hub/router/switch? Does the
uplink port on the hub/router/switch go to a cable/DSL modem?
Are the cables all standard Cat5 cables, or are some crossover
cables?
