Connect Your Wired Devices
All Ethernet ports on the Gateway are Gigabit Ethernet ports and have a maximum speed of 1
Gbps (gigabit per s econd).
Requirements
• Both your network device (for example, a computer, a point of sale terminal, etc.) and
Gateway must have a free Ethernet port.
• Your network device must be configured to obtain an IP address automatically. This is
the default setting.
Procedure
Important: It is recommended to use Category 5e or Category 6 Ethernet cables
with the Gateway.
1. lug one end of the Ethernet cable into one of the RJ-45 Ethernet ports on the back of the
Gateway (see Figure 7).
2. Plug the other end of the Ethernet cable into the Ethernet port of your network device.
3. Your network device is now connected to your network. Use the same procedure to
connect other Ethernet devices (computers, network printers and so on).

Connect Your Wireless Devices
The Gateway has two access points that allow you to connect wireless devices to your
network:
• The 5 GHz IEEE 802.11a/n/ac access point offers superior transfer rates, is less
sensitive to interference and allows you to connect IEEE 802.11a/n/ac wireless clients.
• The 2.4 GHz IEEE 802.11b/g/n access point allows you to connect IEEE 802.11b/g/n
wireless clients. Use this acces s point for wireless clients that do not support 5 GHz.
Caution: If you want to connect your wireless client to the 5 GHz access point,
make sure that your wireless client supports 5 GHz connections.
To connect your device:
• Using the Wi-Fi Protected Setup (WPS), proceed with How to Connect Your Wireless
Client Via WPS.
• By manually entering the settings, proceed with How to Manually Connect Your Wireless
Client.
How to Connect Your Wireless Client Via WPS
Wi-Fi Protected Setup (WPS) allows you to add new wireless clients to your local network in a
swift and easy way, without the need to enter any of your wireless settings (network name,
wireless network key, encryption type).
Both the 2.4 GHz as the 5 GHz access points of your Gateway support WPS.
CGA4131 Business Gateway Setup and User Guide 11
Setup
Requirements
• Your wireless client must support WPS. Check the documentation of your wireless client
for this.
• Your Gateway must use WPA/WPA2-PSK (TKIP/AES) encryption (default encryption) or
WPA2-PSK ( AES) en cryption.
WPS methods
The following WPS methods are supported by your Gateway:
• Push Button Configuration (PBC): Place both the wireless client and the Gateway in
registration mode by pushing a hardware or software button.
• PIN code entry on the wireless client: Enter the Gateway’s WPS PIN code on the
wireless client. For more information, see How to Start a WPS Session.
• PIN code entry on the Gateway: Enter the wireless client’s WPS PIN code on the
Admin Tool. For more information, see How to Start a WPS Session.
Procedure for PBC
Proceed as follows:
1. Start WPS on your wireless client.
2. On the Gateway, press and hold the WPS button for at least 5 seconds and then release
it.
Result: The WPS button LED will start blinking. This indicates that the Gateway is now
searching for wireless clients that are in registration mode.
Figure 8: WPS Button
The Gateway is now exchanging the security settings with the wireless client. Your wireless
client will prompt you when it is connected to the access point.
CGA4131 Business Gateway Setup and User Guide 12
Setup
Troubleshooting
If you are having trouble connecting your wireless client via WPS, this may be caused by one
of the following reasons:
• WPS cannot be correctly executed: Configure your wireless manually. For more
information, see How to Manually Connect Your Wireless Client.
• Your wireless client is out of range: If possible, move your wireless client closer to your
Gateway or use a wireless repeater to extend the range of your wireless network.
How to Manually Connect Your Wireless Client
Requirements
• Your network device must be equipped with a Wi-Fi Certified wireless client.
• Your network device must be configured to obtain an IP address automatically. This is
the default setting.
Procedure
If you want to connect a computer using the wireless network, configure the wireless client on
your computer with the wireless settings printed on the Gateway's back panel label.
The Gateway’s back panel contains two items needed to establish a Wi-Fi connection:
• SSID (“Network Name”) is the name of the network. Either the 2.4GHz or 5GHz network
name can be used.
• Passphrase is the password used for the network name selected.
To configure these settings on:
• Windows 10, proceed with How to Connect Your Computer on Windows 10.
• Windows 8, proceed with How to Connect Your Computer on Windows 8.
• Windows 7, proceed with How to Connect Your Computer on Windows 7.
• Windows Vista, proceed with How to Connect Your Computer on Windows Vista.
• Windows XP, proceed with How to Connect Your Computer on Windows XP
• Mac OS X, proceed with How to Connect Your Computer on Mac OS X.
• On another operating system, consult the help of your wireless client or operating
system.
