The figure below shows a sample setup of GWN76xx in standalone mode:

Figure 1: Standalone Architecture Example

USING DEFAULT SSID

The GWN76xx can be used as standalone access point out of box, or after factory reset with Wi-Fi enabled by default. Users can simply power on the GWN76xx and connect it to the network to start using Wi-Fi access.

GWN76xx will broadcast a default SSID based on its MAC address GWN[MAC’s last 6 digits] and a random password.

Note that GWN76xx’s default SSID and password information are printed on the MAC tag of the unit as shown on the below figure.

Figure 2: MAC Tag Label

To connect, Wi-Fi clients need to scan for Wireless networks, select SSID broadcasted from GWN76xx and enter password as printed in the label tag on the back of GWN76xx.

CREATE CUSTOM SSID

This section describes needed steps to manage and customize SSID and Wi-Fi settings, first by discovering the unit IP address, accessing its web interface and editing its configuration depending on environment needs.

Discover GWN76xx

Once the GWN76xx is powered up and connected to the network correctly, users can discover the GWN76xx using one of the following methods:

Method 1: Discover GWN76xx using its MAC address

Client Bridge Support

Configures the client bridge support to allow the access point to be configured as a client for bridging wired only clients wirelessly to the network.


When an access point is configured in this way, it will share the Wi-Fi connection to the LAN ports transparently.


Once a SSID has a Client Bridge Support enabled, the AP adopted in this SSID can be turned in to Bridge Client mode by click the Bridge button.

Client Time PolicySelect a time policy to be applied to all clients connected to this SSID.
Use MAC FilteringChoose Blacklist/Whitelist to specify MAC addresses to be excluded/included from connecting to the zone’s Wi-Fi.
Default is Disabled.

Client Isolation

Client isolation feature blocks any TCP/IP connection between connected clients to GWN76XX’s Wi-Fi access point. Client isolation can be helpful to increase security for Guest networks/Public WiFi. Three modes are available:

  • Radio Mode: Wireless clients can access to the internet services, GWN7xxx router and the access points GWN76XX but they cannot communicate with each other.
  • Internet Mode: Wireless clients will be allowed to access only the internet services and they cannot access any of the management services, either on the router nor the access points GWN76XX.
  • Gateway MAC Mode: Wireless clients can only communicate with the gateway, the communication between clients is blocked and they cannot access any of the management services on the GWN76XX access points.
Gateway MAC AddressThis field is required when using Client Isolation, so users will not lose access to the Network (usually Internet). Type in the default LAN Gateway’s MAC address (router’s MAC address for instance) in hexadecimal separated by “:”. Example: 00:0B:82:8B:4D:D8
RSSI EnabledCheck to enable RSSI function, this will lead the AP to disconnect users below the configured threshold in Minimum RSSI (dBm).
Minimum RSSI (dBm)Enter the minimum RSSI value in dBm. If the signal value is lower than the configured minimum value, the client will be disconnected. The input range is from “-94” or “-1”.

Beacon Interval

Configures interval between beacon transmissions/broadcasts.


The Beacon signals help to keep the network synchronized and provide main information about the network such as SSID, Timestamp…

  • Using High Beacon Interval: AP will be sending beacon broadcast less frequently. This will help to get better throughput, thus better speed/performance. It also helps to save WiFi clients energy consumption.
  • Using Low Beacon Interval: AP will be sending beacon broadcast more frequently. This can help in environments with weak signal areas; sending more frequently beacons will increase chances to be received by WiFi clients with weak signal.

Notes:


  • When AP enables several SSIDs with different interval values, the max value will take effect.

  • When AP enables less than 3 SSIDs, the interval value which will be effective are the values from 40 to 500.

  • When AP enables more than 2 but less than 9 SSIDs, the interval value which will be effective are the values from 100 to 500.

  • When AP enables more than 8 SSIDs, the interval value which will be effective are the values from 200 to 500.

  • Mesh feature will take up a share when it is enabled.

Default value is 100ms. Valid range: 40 – 500 ms.

DTIM Period

Configures the frequency of DTIM (Delivery Traffic Indication Message) transmission per each beacon broadcast. Clients will check the AP for buffered data at every configured DTIM Period. You may set a high value for power saving consideration.


Default value is 1, meaning that AP will have DTIM broadcast every beacon. If set to 10, AP will have DTIM broadcast every 10 beacons.


Valid range: 1 – 10.

Multicast to Unicast

Once selected, AP will convert multicast streams into unicast streams over the wireless link. Which helps to enhance the quality and reliability of video/audio stream and preserve the bandwidth available to the non-video/audio clients.

Enable Voice Enterprise

Check to enable/disable Voice Enterprise. The roaming time will be reduced once enable voice enterprise.

  • The 802.11k standard helps clients to speed up the search for nearby APs that are available as roaming targets by creating an optimized list of channels. When the signal strength of the current AP weakens, your device will scan for target APs from this list.
  • When your client device roams from one AP to another on the same network, 802.11r uses a feature called Fast Basic Service Set Transition (FT) to authenticate more quickly. FT works with both pre-shared key (PSK) and 802.1X authentication methods.

  • 802.11v allows client devices to exchange information about the network topology, including information about the RF environment, making each client network aware, facilitating overall improvement of the wireless network.

Note: 11R is required for enterprise audio feature, 11V and 11K are optional. This field is available only when “Security Mode” is set to “WPA/WPA2” or “WPA2”.

Enable 11R

Check to enable 802.11r. This field is available only when “Security Mode” is set to “WPA/WPA2” or “WPA2”.

Enable 11K

Check to enable 802.11k

Enable 11V

Check to enable 802.11v

ARP Proxy

This option will enable GWN AP to answer the ARP requests from its LAN for its connected WiFi clients. This is mainly to reduce the airtime consumed by ARP Packets
