Short GI
This field displays only when you select 802.11b/g/n, 802.11n only in
2.4G band or 802.11n only in 5G band in the Mode Select field.
2.4G band or 802.11n only in 5G band in the Mode Select field.
Check this to use Short GI (Guard Interval). The guard interval is the gap
introduced between data transmission from users in order to reduce
interference. Reducing the GI increases data transfer rates but also
increases interference. Increasing the GI reduces data transfer rates but
also reduces interference.

Service Data Units) into one large A-MPDU (Aggregate MAC Protocol Data
Unit). This function allows faster data transfer rates.

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 300Mbps. However, not all devices support 40MHz channels.

Select the channel bandwidth you want to use for your wireless network.
It is recommended that you select 20/40 (20/40 MHz). This allows the
ZyXEL Device to adjust the channel bandwidth depending on network
conditions.
