LABEL DESCRIPTION
Main WiFi
Enable Main WiFi Select Enable to activate the 2.4G and/or 5G WiFi. Select Disable to turn it off.
2.4G/5G Name The Service Set Identity (SSID) identifies the WiFi with which a WiFi client is associated. Enter a
(SSID) name (up to 32 printable characters found on a typical English language keyboard) for the
WiFi.
Click the Keep 2.4G & 5G name the same check box to use the same SSID for 2.4G and 5G
WiFi network.
Security Mode Select the security mode you want to apply to the NBG7815. See
more information on security mode.
Password The password has two uses:
• Manual: Manually enter the same password on the NBG7815 and the client. Enter 8 – 63
ASCII characters or exactly 64 hexadecimal ('0 – 9', 'a – f') characters.
• WPS: When using WPS, the NBG7815 sends this password to the client.
Click the eye icon
slashed
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 2.4G bandwidth from 40 MHz
to 20 MHz if it detects interference from other 2.4G access points. The NBG7815 automatically
changes the 2.4G bandwidth back to 40 MHz when it detects the interference is gone.
Note: This setting only takes effect if 2.4G Bandwidth is set to 40 MHz.
MU-MIMO
Multi-User Multiple-Input, Multiple-Output (MU-MIMO) allows an AP to transmit to multiple groups of MU-MIMO-
enabled WiFi clients at the same time, using a technology called RF multipath. WiFi 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 WiFi clients at the same time, by dividing channel bandwidth into smaller resource units (RUs). OFDMA-
enabled WiFi 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 WiFi 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.
