SSID: The SSID (Service Set Identification) is also known as the wireless network
name, which is used to uniquely identify a wireless network. It must be between 1
and 32 characters long, and it is case sensitive.
Wireless Mode: Specify the wireless modes of the Device. The options are 11g
Only, 11n Only and 11b/g/n Mixed.

11g Only: Pure 802.11g mode, in which the maximum rate is up to 54Mbps.
The wireless clients in compliance with the IEEE 802.11g standard can be
connected to the Device.

11n Only: Pure 802.11n mode, in which the maximum rate is up to 300Mbps.
The wireless clients in compliance with the IEEE 802.11n standard can be
connected to the Device.

11b/g/n Mixed: The wireless clients in compliance with IEEE 802.11b,
802.11g or 802.11n standard will be connected according to their wireless
modes, with the maximum rates of 11M bps, 54M bps and 300M bps
respectively.
Channel: Select the frequency bands in which the wireless network works; it
provides automatic options, which means that the Device can automatically select
the optimal frequency band. The wireless devices in the same frequency band will
interfere with each other. If there are multiple wireless devices around the Device,
please select a frequency band different from that of other wireless devices when
setting the channel.
Channel Width: The channel bandwidth occupied by the wireless data
transmission, with the options: 20M/40M and 20M. Note that this parameter
works only with the wireless clients accessed using the 802.11n standard; for
those using the 802.11b or 802.11g standard, only the channel bandwidth of 20M
can be used:

20M/40M: If selected, the wireless clients accessed using the 802.11n
standard will use the channel bandwidths of 20M or 40M according to the
results of the negotiation with the accessed peer device.
