Wireless Security Overview
To guard your home network against attack and prevent unauthorised access, it is very important that you
secure it with correct authentication type, encryption and strong secure password. By default, NL19MESH
has secure authentication type, encryption and randomly generated unique secure password however you
can update it to more secure password or change authentication type or encryption method based on your
wireless clients.
If you are planning to change the Wi-Fi network name, password, authentication type or encryption it is
recommended to keep it same for both 2.4 GHz and 5 GHz band. This will allow the wireless clients to auto
select suitable band and for optimum MESH performance.
Changing the wireless password
1Connect your device to the Gateway using wired or wireless connection.
Important –
A computer connected using an Ethernet cable is strongly recommended.
2Open a web browser (such as Internet Explorer, Google Chrome, Safari or Mozilla Firefox), type
following address into the address bar and press Enter.
http://192.168.20.1
3Enter Gateway Login Username and Password printed on the label at the bottom of Gateway and
press Login.

Wi-Fi 2.4GHz/WiFi 5GHz
The gateway allows you to maintain separate wireless settings for both 2.4GHz and 5GHz wireless services.
1Select the service you want to use (or both) and separately configure them:
2.4 GHz Wireless configuration pages
5 GHz Wireless configuration pages
Important –
It is recommended that you use the same Wi-Fi Network Name (SSID) and password for both 2.4 GHz and
5 GHz Wi-Fi bands, this allows clients to choose the more suitable band automatically.
Wireless –Basic (Change SSID)

NetComm 8386, and enter a new SSID.
4Press the Apply button.
Wireless –Security
Selecting a wireless security type:
We highly recommend that you do not change the Network authentication type.
Use the default “WPA2-PSK” authentication type because it is the most secure one. Changing it to another
type such as WEP will compromise the security of the gateway.
Selecting a wireless security key:
We do not recommend changing the wireless security key from the default setting. It is randomly generated,
reasonably secure and unique to each unit. Your client devices will still have same password even if the
Gateway is reset to factory default settings. If you want to change it to a more secure password, add
numbers and special characters along with upper-case and lower-case characters. Generally speaking, the
longer the password, the more secure it is.
To change the Wi-Fi security key, navigate to Wi-Fi > 2.4GHz/5GHz > Security.
Delete all the dots (encrypted password) in the WPA passphrase text entry field. Enter a new password, click
Click here to display button to verify the password and click Apply button.
