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.)
SGI — Enables the Short Guard Interval (SGI) in the following 802.11 modes:
5 GHz radio; 802.11a, 802.11a+ n, 802.11ac+a+n.
2.4 GHz radio; 802.11 b g+ n.
The 802.11n draft specifies two guard intervals: 400ns (short) and 800ns
(long). Support of the 400ns Short Guard Interval is optional for transmit and
receive. The purpose of a guard interval is to introduce immunity to
propagation delays, echoes, and reflections to which digital data is normally
very sensitive. Enabling SGI sets it to 400ns. (Default: Disabled)
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.
