LABEL DESCRIPTION
Main WiFi
Enable Main WiFi Select Enable to activate the 2.4GHz and/or 5GHz wireless LAN. Select Disable to turn it off.
2.4G/5G Name
(SSID)
The Service Set Identity (SSID) identifies the wireless LAN with which a wireless client is
associated. Enter a name (up to 32 printable characters found on a typical English language
keyboard) for the wireless LAN.
Click the Keep 2.4G & 5G name the same check box to use the same SSID for 2.4G and 5G
wireless network.
Security Mode Select the security mode you want to apply to the NBG7815.
Password The password has two uses:
• Manual: Manually enter the same password on the Zyxel Device and the client. Enter 8-63
ASCII characters or exactly 64 hexadecimal (‘0-9’, ‘a-f’) characters.
• WPS: When using WPS, the Zyxel Device sends this password to the client.
Click the eye icon to show or hide the password of your wireless network. When the eye
icon is slashed , you’ll see the password in plain text. Otherwise, it is hidden.
2.4G/5G Channel Select a channel from the drop-down list box. The options vary depending on the frequency
band and the country you are in.
Advanced Settings
Note: Please check if your device supports these features before enabling them.
OBSS Select Enable to have the NBG7815 automatically change the 2.4Ghz bandwidth from 40Mhz
to 20Mhz if it detects interference from other 2.4Ghz access points. The NBG7815
automatically changes the 2.4Ghz bandwidth back to 40Mhz when it detects the
interference is gone.
Note: This setting only takes effect if 2.4Ghz Bandwidth is set to 40Mhz.
MU-MIMO
Multi-User Multiple-Input, Multiple-Output (MU-MIMO) allows an AP to transmit to multiple groups of MU-MIMO-
enabled wireless clients at the same time, using a technology called RF multipath. Wireless clients in the same
group can also co-ordinate in order to transmit to the AP at the same time. MU-MIMO helps decrease client waiting
time and increase network throughput.
Note: WiFi6 (802.11ax) can support more client groups than WiFi5 (802.11ac). Clients are grouped
based on each client's distance and direction from the AP.
Down Link Select Enable to allow down link MU-MIMO on the NBG7815. The NBG7815 can then transmit
data to several clients simultaneously without a decrease in connection speed.
Up Link Select Enable to allow up link MU-MIMO on the NBG7815. Several clients can then transmit
data to the NBG7815 simultaneously without a decrease in connection speed.
OFDAM
Orthogonal Frequency-Division Multiple Access (OFDMA) allows an AP to transmit data to multiple OFDMA-
enabled wireless clients at the same time, by dividing channel bandwidth into smaller resource units (RUs). OFDMA-
enabled wireless clients can also co-ordinate in order to transmit to the AP at the same time. OFDMA helps improve
efficiency and increase network throughput, especially when wireless clients are transmitting a large number of
small data packets.
Down Link Select Enable to allow down link OFDAM on the NBG7815. The NBG7815 can then transmit
data to several clients simultaneously without a decrease in connection speed.
Up Link Select Enable to allow up link OFDAM on the NBG7815. Several clients can then transmit data
to the NBG7815 simultaneously without a decrease in connection speed.
