What domains and ports are used by GWN Cloud?

Can I create a Black/White list under an SSID?

Yes, you can apply a Black/White list by following the steps below:

1. Create a MAC list in Clients→ Client Access.
2. Connect to the GWN AP’s Web GUI and go to Network Group
3. Edit or create a new Network Group; and go to WiFi

Does the GWN AP have a power adapter? Can it be powered by PoE/PoE+?

To power on the GWN AP, you can use a PoE/PoE+ Switch or PoE injector via NET/PoE port. The GWN APs are Power over Ethernet 802.3af/802.3at compliant.

Does the GWN AP support roaming? Is it seamless?

Yes the GWN AP supports roaming. While the roaming decision is always made by the client device, the GWN AP improves the roaming experience by offering the Minimum RSSI feature and 802.11k/v/r fast roaming. Minimum RSSI can be enabled and configured under the SSID settings. It helps to de-authenticate a client device when its signal level is below the configured threshold, forcing the client device to roam to another access point with a stronger signal.

How can I add a paired GWN AP to a Network Group?

How do I determine the IP Address of my GWN AP?

The GWN AP network ports are configured by default as a DHCP client, you can discover its IP using one of the below methods:

Method 1: Discover the GWN AP using its MAC address

1. Find the MAC address on the GWN AP box, or on the underside of the AP.
2. From a computer connected to same network as the GWN AP, type the following address into your browser using the GWN’s MAC address: https://gwn_<mac>.local

For example, if a GWN AP has the MAC address 00:0B:82:8B:4E:28, you would type the following into the browser: https://gwn_000b828b4e28.local/

Method 2: Using the GWN Discovery Tool

I cannot access the web interface, what could be the issue?

• Make sure that the GWN AP is powered on and connected correctly to the network.
• Make sure that your computer is connected to the same network as the GWN AP, or to its SSID.
• Use the Discovery Tool to identify the IP address of the GWN AP.
• Make sure that GWN AP is not already paired with another controller, if it is paired with another controller, it can only be managed from the Controller’s Web GUI.

My access point won’t pair under the GWN AP controller, what can I do?

Make sure that the GWN AP is connected to same network as the GWN AP acting as the controller.

If it is already discovered, but cannot be paired, please check one of the below causes:

• This unit is acting also as a Controller. In this case, the unit must be reset to factory default.
• This unit is already paired under another GWN AP Controller. In this case the unit needs to be unpaired from the previous Controller to make it available for pairing again.

What do the LED patterns mean?

The GWN AP has different LED patterns that indicate different statuses. This allows users to easily determine the status of the GWN AP. The key below explains the meaning behind different patterns.

What happens to the paired APs if the AP configured as the Controller dies? Answer: If the controller AP dies, follow the below steps:

1. First unpack the gz and tar files. After unpacking, the file will become a folder. Within that folder, there will be a configuration file called grandstream under the directory grandstream/etc/config/. Please note: this grandstream file has no extension, but editable as plain text.

2. Edit the Grandstream file by modifying the line which was: config ap 'your_master_MAC' to config ap 'your_new_master_MAC' 

3. Next, archive the folder back to grandstream.tar and then to grandstream.tar.gz

4. Finally, upload this configuration file to your new Controller AP. Once this is completed, the new Controller AP will control all the paired APs. 

What happens to the paired APs if the AP configured as the Controller fails?

If the controller AP fails, follow the below steps:

1. First unpack the compressed backup config files. After unpacking, the file will become a folder. Within that folder, there will be a configuration file called Grandstream under the directory grandstream/etc/config/. Please note: this Grandstream file has no extension, but is editable as plain text.
2. Edit the Grandstream file by modifying the line which was: config ap 'your_master_MAC' to config ap 'your_new_master_MAC'
3. Next, archive the folder back to grandstream.tar and then to grandstream.tar.gz
4. Finally, upload this configuration file to your new Controller AP. Once this is completed, the new Controller AP will control all the paired APs.
