Important notice
This device, like any wireless device, operates using radio signals which cannot guarantee the transmission
and reception of data in all conditions. While the delay or loss of signal is rare, you should not rely solely on
any wireless device for emergency communications or otherwise use the device in situations where the
interruption of data connectivity could lead to death, personal injury, property damage, data loss, or other
loss. NetComm Wireless accepts no responsibility for any loss or damage resulting from errors or delays in
transmission or reception, or the failure of the NetComm Wireless Wi-Fi 6 Gateway to transmit or receive
such data.

Basic setup
Normally your CF40MESH Wi-Fi 6 Gateway is shipped pre-configured with connection settings appropriate
for your internet and Wi-Fi services. Normally you will not be required to use the tools and settings found in
this section.
However, if the pre-configured default profile does not connect, you should run through the Basic Setup
wizard described in this section.
This wizard prompts you for the details necessary to set up your internet connection and helps you to
configure the Wi-Fi on the gateway. If you are unsure of the settings to enter, please contact your Internet
Service Provider.
To access the Basic setup wizard, select Basic Setup from the menu on the left.
Figure 6 - Basic Setup
To complete the wizard, you will need to know a few settings about your internet connection, such as
Connection Type, VLAN ID and username and password. If you don’t know what these are, you should
contact your internet service provider.
1Select the connection type and enter the required details depending on the connection type selected.
When you have entered the details for your connection, select the Next button.
2Enter an SSID (network name) and password for your wireless network. These are required whenever
you want to connect a wireless device to your network.
Note
–
If you are replacing an existing wireless network, you can set the same username and password on the Wi-Fi 6 Gateway
and all your devices will connect automatically to the new one.

Field Description
Band Steering
Band steering is a technique that aims to optimise the band (2.4GHz or
5GHz) that clients connect to based on their signal strength, with a focus
on encouraging wireless devices to prioritise the less congested 5GHz
network where possible.
If you have some older devices and experience connection problems, you
may consider disabling this option, but in most cases, band steering
improves the performance of your wireless network.
WiFi Status
Enables or disables the Main Wi-Fi network of your Wi-Fi 6 Gateway.
SSID
The SSID is also known as the wireless network name that appears when
you scan for nearby wireless networks.
WiFi Password
The password for the wireless network. This is the password that must be
entered when attempting to connect to the Wi-Fi 6 Gateway’s Wi-Fi
network.
Security Mode
This is the security protocol used to secure your wireless network. The
default setting is WPA2-PSK/WPA3-SAE. This is a combination of WPA2 and
WPA3. If the wireless device supports WPA3, it will use that as it is the
newer and more secure protocol.
If you have any problems with connecting to Wi-Fi, try to select “WPA2” or
“WPA2-PSK” as the security mode as it is possible that some devices could
have trouble connecting with the WPA3 protocol.
Encrypt Algorithm
The Advanced Encryption Standard (AES) is the most secure wireless
encryption standard and is the default setting on the Wi-Fi 6 Gateway. As it
is the most secure option, no other options are provided.
SSID Hidden
When this option is enabled, your wireless network will not appear when a
device does a scan for nearby wireless networks. This means that a
wireless device must use the manual connection method and enter the
SSID and password together in order to connect.

Guest WiFi
Use a Guest network to allow others to use your internet connection while preserving the security of your
own local network.
To access this page, select WiFi from the menu on the left, then choose Guest WiFi from the submenu.
Figure 17 - Guest WiFi settings page
The Guest WiFi page provides you with the option of configuring up to six guest networks in total; three on
the 2.4GHz band and three on the 5GHz band. Refer to Table 3 – Main WiFi – Descriptions for a description of
each field.
Each wireless network should run a unique SSID (network name) so that it is easily identifiable when a scan
for nearby networks is performed.
