WDS
The Router supports WDS (Wireless Distribution System). WDS enables
one or more Access Points to rebroadcast received signals to extend
range and reach, though this can affect the overall throughput of data.

WDS implementation varies from vendor to vendor. Hence there’s no
assured WDS interoperability with between all devices in the market.
Firewall
From these screens, you can configure settings for the firewall.
Your Router is equipped with a firewall that will protect your network
from a wide array of common hacker attacks including Ping of Death
(PoD) and Denial of Service (DoS) attacks. You can turn the firewall
function off if needed. Turning off the firewall protection will not leave
your network completely vulnerable to hacker attacks, but 3Com
recommends that you leave the firewall enabled whenever possible.
