●
Radio Mode
Shows the mode of the WLAN interface.
●
Frequency Band
Specify the frequency band. In client mode, dual-frequency operation is also possible.
– 2.4 GHz
– 5 GHz
– 2.4 GHz + 5 GHz (only in client mode)
Note
Configuring WLAN interfaces of the W786-2IA RJ-45 for different frequency bands
If both WLAN interfaces are configured for the same frequency band on this device, there
may be mutual influence or interference.
This applies in particular when there is a high
data throughput.
●
WLAN Mode 2.4 GHz/WLAN Mode 5 GHz
Select the required transmission standard for the configured frequency band. The
selection depends on the country setting.
– Auto (in client mode only)
The transmission standard is determined automatically (2.4 GHz, 5 GHz and 2.4 GHz
+ 5 GHz).
– 802.11a
The transmission standard IEEE 802.11a (5 GHz) is set.
– 802.11g
The transmission standard IEEE 802.11g (2.4 GHz) is set. This transmission standard
is downwards compatible with IEEE 802.11b
– 802.11n
The transmission standard IEEE 802.11n (2.4 GHz and 5 GHz) is set. This
transmission standard is downwards compatible with IEEE 802.11a and IEEE
802.11g.
– 802.11 only
The transmission standard IEEE 802.11n (2.4 GHz and 5 GHz) is set. This
transmission standard is downwards compatible with IEEE 802.11a and IEEE
802.11g.
Note
If you select the transmission standard "802.11n", "802.11n only" or "Auto" (only in client
mode), you cannot set the threshold value of the frag
mentation length see
"Fragmentation Length Threshold" in "Interfaces > WLAN > Advanced".
