Ports 1-8
These eight LAN (Local Area Network) ports connect to net-
work devices, such as PCs, print servers, and network
attached storage (NAS). Each of the ports will auto-detect
whether a straight-through or crossover cable is plugged into
it, so there is no need for an uplink port. Any one of the eight
ports can serve as an uplink port to other network devices.

1. If the Router is having problems connecting to the Internet, press the Reset
button for just a moment with a paper clip or a pencil tip. This clears up any
jammed connections, and is similar to pressing the Reset button on your PC
to reboot it.
