5 Configuring Access Point Settings
Figure 40 shows what a user on a Microsoft Windows XP client sees when the user searches
for wireless networks within range.
Figure 40. Networks Available to the Wireless Client
Although the wireless client finds five different wireless networks, these networks are all on
the same access point. The D-Link Access Point looks like five separate access points to the
wireless client.
In this example, the administrator configured multiple VAPs based on different functional
groups within the company. Each VAP has a different SSID, security settings, and VLAN ID
to separate traffic.
You can associate the same network (SSID) with multiple VAPs. When you do this, the VAPs
look like the same network to wireless clients. Some administrators configure VAPs with
identical settings on each radio so that wireless clients can connect to the same network
whether their wireless adapters are 802.11a or 802.11b/g compatible.
By default, both radios have the same networks assigned to the VAPs, and only VAP0 is
enabled. You must configure each radio independently. In other words, if you enable
additional VAPs on one radio, it does not affect the VAPs on the second radio.
Configuring a VAP for L3 Tunnels
This section provides an overview of the L3 Tunneling feature. For a detailed configuration
example of a network that uses L3 roaming, see Appendix C, “L3 Roaming Example” on
page 187.
The L3 Tunnel feature allows mobile stations to maintain their IP connections while roaming
from one access point to another access point even when these access points are attached to
