Figure 30: Advanced Radio Settings
The following items are displayed in this section of the Wireless Settings page:
■
Tx Power — Adjusts the power of the radio signals transmitted from the access
point. The higher the transmission power, the farther the transmission range.
Power selection is not just a trade off between coverage area and maximum
supported clients. You also have to ensure that high-power signals do not
interfere with the operation of other radio devices in the service area. (The
range of power settings and defaults are dependent on the AP model and the
Country setting.)
VLAN Settings
VLANs (virtual local area networks) are turned off by default. If turned on they will
automatically tag any packets passed to the LAN port from the relevant VAP (virtual
access point).
The access point can employ VLAN tagging to control access to network resources
and increase security. VLANs separate traffic passing between the access point,
associated clients, and the wired network. You can create up to 16 VLAN tagged
networks.
Note the following points about the access point’s VLAN support:
■
If an Ethernet LAN port on the access point is assigned a VLAN ID, any traffic
entering that port must be also tagged with the same VLAN ID.
■
Wireless clients associated to the access point can be assigned to a VLAN.
Wireless clients are assigned to the VLAN for the VAP interface with which they
are associated. The access point only allows traffic tagged with correct VLAN
IDs to be forwarded to associated clients on each VAP interface.
■
When VLAN support is enabled on the access point, traffic passed to the wired
network is tagged with the appropriate VLAN ID. When an Ethernet port on the
access point is configured as a VLAN member, traffic received from the wired
network must also be tagged with the same VLAN ID. Received traffic that has
an unknown VLAN ID or no VLAN tag is dropped.
■
When VLAN support is disabled, the access point does not tag traffic passed to
the wired network and ignores the VLAN tags on any received frames.
