Network Interface | Wireless | Advanced
Use the
network interface | wireless | advanced
menu to configure the layer 2 client isolation, SSID
broadcasting or threshold values or wireless card output power:
Figure 87 – Advanced Wireless Setting
Layer 2 Isolation
– Layer 2 wireless client separation. Connected clients with user isolation function
enabled cannot access each other directly. The clients are isolated from each other using their MAC
addresses [enabled/disabled].
SSID
Broadcasting
– when enabled, your AP’s SSID is visible in the networks list while scanning the
available networks for wireless client. When disabled, the AP’s SSID is not visible in the available
network list (SSID is not broadcasted with its Beacons) [enabled/disabled]. By default the SSID
broadcasting is enabled.
Fragmentation
Threshold
–the fragmentation threshold, specified in bytes, determines whether
packets will be fragmented and at what size. On an 802.11 wireless LAN, packets exceeding the
fragmentation threshold are fragmented, i.e., split into, smaller units suitable for the circuit size.
Packets smaller than the specified fragmentation threshold value are not fragmented [[256-2346]
default: 2346 (2346 means that fragmentation is disabled)].
RTS
Threshold
– when set, this setting specifies the maximum packet size beyond which the
Wireless LAN Card invokes its RTS/CTS mechanism. Packets that exceed the specified RTS
threshold trigger the RTS/CTS mechanism. The NIC transmits packets smaller than this threshold
without using RTS/CTS [[0-2347] default: 2347 (2347 means that RTS is disabled)].
Output
Power
– the wireless card transmission output power in dBm [0-31].
Antenna
Gain
(dBi)
– is the gain of the connected antenna in relation to an isotropic radiated power.
Total output power (wireless
output power
plus
antenna
gain
) should comply with
local radio regulations. Refer to the Appendix:
C) Regulatory Domain/Channels.
Network Interface | Wireless | Security
Secure your wireless network use one of the available encryption methods:
WEP
(Wired Equivalent Privacy) with 64-bit/128-bit encryption
WPA
(Wi-Fi Protected Access) with pre shared key or with RADIUS server
The WPA is a far stronger protocol and fixes the weaknesses in WEP. To enable the WPA security for
your WLAN you will need:
An access point that has WPA support (e.g. Gemtek Systems P-560)
A wireless network card that has WPA drivers available
A mobile client that supports WPA and your operating system
To configure the WPA with pre-shared key security on the P-560 use the
network interface |
wireless | security
menu, select the WPA with pre-shared key security method and enter the pre-
shared key:
