Bandwidth Select whether the P-2812HNU-51c uses a wireless channel width of
20MHz or 40MHz.
A standard 20MHz channel offers transfer speeds of up to 150Mbps
whereas a 40MHz channel uses two standard channels and offers speeds
of up to 300 Mbps.
40MHz (channel bonding or dual channel) bonds two adjacent radio
channels to increase throughput. The wireless clients must also support 40
MHz. It is often better to use the 20 MHz setting in a location where the
environment hinders the wireless signal.
Select 20MHz if you want to lessen radio interference with other wireless
devices in your neighborhood or the wireless clients do not support
channel bonding.

The SSID (Service Set IDentity) identifies the service set with which a
wireless device is associated. Wireless devices associating to the access
point (AP) must have the same SSID. Enter a descriptive name (up to 32
printable 7-bit ASCII characters) for the wireless LAN.

connected to the wireless LAN and you change the P-
2812HNU-51c’s SSID or wireless security settings, you will lose
your wireless connection when you press Apply to confirm. You
must then change the wireless settings of your computer to
match the P-2812HNU-51c’s new settings.
