Access Point 
Basic 
Wireless (2.4GHz or 5GHz) > Wireless Network 
This section outlines the available features to configure for both wireless 2.4Ghz and 
5GHz when Access Point mode is selected.  
1. Log into your management page (see “Access the management page” on page 16). 
2. Click on the wireless band you would like to configure and click Wireless Network.  
3. Configure the below settings and click Apply to save settings.  
4. Click on Save/Reload button located on the top left section to apply settings. 
  Wireless Mode: If all of the wireless devices you want to connect with this Access 
Point can connect in the same transmission mode, you can improve performance 
slightly by choosing the appropriate mode. If you have some devices that use a 
different transmission mode, choose the appropriate mode.  
2.4GHz Wireless 
o B/G/N mixed: Select this mode for the best compatibility. This mode allows older 
802.11b and 802.11g wireless devices to connect to the router in addition to 
newer 802.11n devices. 
o B/G mixed: This mode only allows devices to connect to the router using older 
and slow 802.11b or 802.11g technology and it thereby reduces the router’s 
maximum speed to 54Mbps (typically not recommended). 
o N only: This mode only allows newer 802.11n devices to connect to your router. 
This mode does ensure the highest speed and security for your network, however 
if you have older 802.11g wireless clients, they will no longer be able to connect 
to this router.  
o G only: This mode only allows devices to connect to the router using older and 
slow 802.11g technology (typically not recommended). 
o B only: This mode only allows devices to connect to the router using older and 
slow 802.11b technology (typically not recommended). 
Note: Please check the specifications on your wireless devices for the highest 
wireless capability supported first before applying these settings. If you are 
unsure, it is recommended that you keep the default setting (B/G/N mixed) for the 
best compatibility. 
5GHz Wireless  
o A only: This mode only allows devices to connect to the router using older and 
slow 802.11a technology (typically not recommended). 
o A/N mixed: This mode only allows devices to connect to the router using older 
and slow 802.11a or 802.11n technology and it thereby reduces the router’s 
maximum speed to 54Mbps (typically not recommended). 
o N only: This mode only allows newer 802.11n devices to connect to your router. 
This mode does ensure the highest speed and security for your network, however 
if you have older 802.11a wireless clients, they will no longer be able to connect 
to this router.  
o N/AC mixed: Select this mode for the best compatibility. This mode allows older 
802.11a wireless devices to connect to the router in addition to newer 802.11ac 
devices.
