WAP7205 User’s Guide

The screen varies depending on what you select in the Security Mode field.

Channel Width

Select the wireless channel width used by WAP7205.

A standard 20 MHz channel offers transfer speeds of up to 150Mbps whereas a 40 MHz channel 
uses two standard channels and offers speeds of up to 300Mbps. 

Because not all devices support 40 MHz channels, select Auto 20/40 MHz or Auto 20/40/80 MHz 
to allow the WAP7205 to adjust the channel bandwidth automatically.

40 MHz (channel bonding or dual channel) bonds two adjacent radio channels to increase 
throughput. A 80 MHz channel consists of two adjacent 40 MHz channels. The wireless clients 
must also support 40 MHz or 80 MHz. It is often better to use the 20 MHz setting in a location 
where the environment hinders the wireless signal. 

Select 20 MHz if you want to lessen radio interference with other wireless devices in your 
neighborhood or the wireless clients do not support channel bonding.

802.11 Mode

2.4 GHz is the frequency used by IEEE 802.11b/g/n wireless clients. 5 GHz is the frequency used 
by IEEE 802.11ac/a/n wireless clients.

You can select from the following:

• 802.11b: allows either IEEE 802.11b or IEEE 802.11g compliant WLAN devices to associate 

with the WAP7205. In this mode, all wireless devices can only transmit at the data rates 

supported by IEEE 802.11b.

• 802.11g: allows IEEE 802.11g compliant WLAN devices to associate with the Device. IEEE 

802.11b compliant WLAN devices can associate with the WAP7205 only when they use the 

short preamble type.

• 802.11bg: allows either IEEE 802.11b or IEEE 802.11g compliant WLAN devices to associate 

with the WAP7205. The WAP7205 adjusts the transmission rate automatically according to 

the wireless standard supported by the wireless devices.

• 802.11n: allows IEEE 802.11n compliant WLAN devices to associate with the WAP7205. This 

can increase transmission rates, although IEEE 802.11b or IEEE 802.11g clients will not be 

able to connect to the WAP7205. I

• 802.11gn: allows either IEEE 802.11g or IEEE 802.11n compliant WLAN devices to associate 

with the WAP7205. The transmission rate of your WAP7205 might be reduced.

• 802.11 bgn: allows IEEE802.11b, IEEE802.11g and IEEE802.11n compliant WLAN devices to 

associate with the WAP7205. The transmission rate of your WAP7205 might be reduced.

• 802.11a: allows only IEEE 802.11a compliant WLAN devices to associate with the WAP7205. 
• 802.11a/n: allows both IEEE802.11a and IEEE802.11n compliant WLAN devices to associate 

with the WAP7205. The transmission rate of your WAP7205 might be reduced.

• 802.11a/an/ac: allows both IEEE802.11a, IEEE802.11n and IEEE802.11ac compliant WLAN 

devices to associate with the WAP7205.

Security

Security Mode

Select WPA2-PSK or WPA2 to add security on this wireless network. The wireless clients which 
want to associate to this network must have same wireless security settings as this device. After 
you select to use a security, additional options appears in this screen. See 

 for detailed information on different security modes. Or you can select No Security to allow 

any client to associate this network without authentication.

Note: If the WPS function is enabled (default), only No Security and WPA2-PSK are 

available in this field.
