Channel Selection Set the operating frequency/channel depending on your particular region.
Select a channel from the drop-down list box. The options vary depending on the frequency
band and the country you are in.
Refer to the Connection Wizard chapter for more information on channels. This option is only
available if
Auto Channel Selection is disabled.
Auto Channel
Selection Select this check box for the LTE2566-M634 to automatically choose the channel with the least
interference. De-select this check box if you wish to manually select the channel using the
Channel Selection field.
Operating
Channel This displays the operating frequency/channel depending on your particular region.
Channel Width Select the wireless channel width used by LTE2566-M634.
A standard 20 MHz channel( HT20 ) offers transfer speeds of up to 144 Mbps (2.4G) or 217 Mbps
(5G) whereas a 40 MHz channel( HT40 ) uses two standard channels and offers speeds of up to
300 Mbps (2.4G) or 450 Mbps (5G). An IEEE 802.11ac-specific 80 MHz channel ( HT80 ) offers
speeds of up to 1.3 Gbps.
Because not all devices support 40 MHz and/or 80 MHz channels, select Auto to allow the
LTE2566-M634 to adjust the channel bandwidth automatically.
HT40 (channel bonding or dual channel) bonds two adjacent radio channels to increase
throughput. A HT80 channel consists of two adjacent 40 MHz channels. The wireless clients
must also support HT40 or HT80 . It is often better to use the 20 MHz setting in a location where
the environment hinders the wireless signal.
Select HT20 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 In Wireless Setup for 2.4G network you can select from the following:
• 802.11b Only : allows either IEEE 802.11b compliant WLAN devices to associate with the
LTE2566-M634. In this mode, all wireless devices can only transmit at the data rates
supported by IEEE 802.11b.
• 802.11b/g Mixed : allows either IEEE 802.11b or IEEE 802.11g compliant WLAN devices to
associate with the LTE2566-M634. The LTE2566-M634 adjusts the transmission rate
automatically according to the wireless standard supported by the wireless devices.
• 802.11b/g/n Mixed : allows IEEE802.11b, IEEE802.11g and IEEE802.11n compliant WLAN
devices to associate with the LTE2566-M634. The transmission rate of your LTE2566-M634
might be reduced.
In Wireless Setup for 5G network you can select from the following:
• 802.11a Only : allows only IEEE 802.11a compliant WLAN devices to associate with the
LTE2566-M634.
• 802.11a/n Mixed : allows both IEEE802.11n and IEEE802.11a compliant WLAN devices to
associate with the LTE2566-M634. The transmission rate of your LTE2566-M634 might be
reduced.
• 802.11a/n/ac Mixed : allows both IEEE802.11a, IEEE802.11n and IEEE802.11ac compliant
WLAN devices to associate with the LTE2566-M634. The transmission rate of your LTE2566-
M634 might be reduced.
Security - 2.4G / Security - 5G
Security Mode Select WPA2-PSK or WPA-PSK / WPA2-PSK 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
Section 8.3 on page 63 for detailed information on different security modes. Or you can select
Open to allow any client to associate this network without authentication.
Note: If the WPS function is enabled (default), only Open and WPA2-PSK are
available in this field.
