Hardware Description 
The Barricade connects to the Internet or to a remote site using its ADSL 
RJ-45 port. It can be connected directly to your PC or to a local area 
network using the Fast Ethernet LAN port.
Access speed to the Internet depends on your service type. Full-rate ADSL 
provides up to 8 Mbps downstream and 1 Mbps upstream. G.lite (or 
splitterless) ADSL provides up to 1.5 Mbps downstream and 512 kbps 
upstream. However, you should note that the actual rate provided by 
specific service providers may vary dramatically from these upper limits.
Data passing between devices connected to your local area network can 
run at up to 100 Mbps over the Fast Ethernet port and 54 Mbps over the 
built-in wireless network adapter.
