Connecting Through Ethernet

To connect to the AirLink Helix using Ethernet, simply plug one end of an Ethernet cable into your computer, and plug the other end into either of the Ethernet ports on the AirLink Helix.

There are two Ethernet ports on the Helix. In most configurations, both can be used for LAN connections. In WAN failover mode, one is used for a WAN port to connect to another Internet service like a DSL or cable modem.

Make sure your computer is setup for DHCP addressing. To setup the AirLink Helix for static IP addressing, refer to the LAN Page section in ???Using the ACEmanager???.

AirLink Helix User Guide

Connecting Through Wi-Fi

Wi-Fi is available as an option on some versions of the Helix RT.

To connect wirelessly to the AirLink Helix using a Wi-Fi equipped computer, simply select the network name ???helix??? using the Wi-Fi connection software provided with your operating system or Wi-Fi network interface.

You can customize the network name and other Wi-Fi configuration options using the LAN/Wi-Fi page in the ACEmanager. For more information, see the ???Using the ACEmanager??? chapter.

Note: If you don???t change the default security settings in the ACEmanager for the AirLink Helix, the AirLink Helix is accessible to any Wi-Fi device. For information about Wi-Fi security, see the Security Page section in the ???Using ACEmanager??? chapter.

The AirLink Helix Wi-Fi network is based on the 802.11b/g. By default you can also use computers equipped with 802.11b Wi-Fi hardware because 802.11g is backwards compatible with 802.11b.

If you have trouble connecting automatically to the AirLink Helix using Wi-Fi, try the following:

???Make sure the ???helix??? network name is selected in the list of available networks with your computer???s Wi-Fi connection software.

???Turn your computer???s Wi-Fi connection off and then on again.

???Restart your computer.

???Check to see that your computer???s network configuration is consistent with the configuration of the AirLink Helix. The default AirLink Helix configuration requires your computer to use a DHCP connection.

???For Windows XP users, check to see that you have Service Pack 2 or higher installed. To determine if you have Service Pack 2 installed, open the Control Panel and then open the System application.

???Change the Wi-Fi channel in the AirLink Helix ACEmanager. You may be encountering interference on a certain channel.

???Try turning off WEP or WPA encryption in the ACEmanager. If you can connect when encryption is turned off, you may be entering incorrect WPA or WEP login information into your computer or device.

Where to Find More Help

The Ethernet, Wi-Fi, and TCP/IP network interfaces used by the AirLink Helix comply with industry standards. Connection issues may be related to the proper use of these standards and not the AirLink Helix itself.

Cellular Antennas

The AirLink Helix requires two cellular antennas, as shown in Figure 3-2. Depending on your Helix kit, antennas may or may not be included.

Hardware Overview

Note: This device is not intended for use within close proximity of the human body. Antenna installation should provide for at least a 20 cm separation from the operator.

The Helix will work with most dual band cellular antennas with SMA connectors. Connect antennas directly to the connectors found on the sides of the Helix.

Note: When using a cable to an antenna placed away from the Helix, minimize the length of your cable. All gain from a more advantageous antenna placement can be lost with a long cable to the device. Each external antenna used with an extension cable, should be located 20cm apart from any other antenna.

Cellular

Antennas

Figure 3-2: Cellular Antennas

Note: Use all four antennas for diversity. Using only one cell antenna or one Wi-Fi antenna can cause degraded performance.

The optimal placement of the cellular antenna is upright.

AirLink Helix User Guide

Wi-Fi Antennas

The antennas on the back of the Helix are for transmitting and receiving Wi-Fi signals. Connect antennas directly to the connectors found at the back of the Helix.

Note: Optimal antenna performance can be achieved by orienting the WiFi antennas horizontally.

A single USB modem can be connected to Helix RT. USB modems Compass 598 (Sprint) and Compass 895 (AT&T) are supported. Only one cellular device, that is either the Helix RT or the USB modem operates at a given time. When a USB modem is connected to the Helix RT, it assumes all the functions of the internal radio module to provide WWAN connectivity. Once the USB modem is removed the internal radio module of Helix RT restarts.

Figure 4-1: USB modems : Compass 895 and Compass 598

When a USB modem is connected to the Helix RT, it performs with the other all the features as if it were the Helix RT. WAN failover, APN configuration, and similar features now operate with the USB modem.

Multiple failover options include USB modem in WAN failover feature, so that the software can automatically toggle between:

WAN/Cellular

The WAN/Cellular section allows changes to the cellular connection and main operating mode of the Helix. Some settings may appear differently and are dependent on cellular carrier settings.

The default mode is "Cellular". This uses the onboard cellular module as primary means of connection and enables all other onboard features. Custom connection settings can be included if they are supported by the cellular module.

AirLink Helix User Guide

WAN Failover

WAN Failover allows the Helix to intelligently manage two Internet connections, switching from one to the other as needed. After enabling this mode, Helix will continually test the primary Internet connection. If tests fail, Helix will automatically switch to the secondary connection while continuing to test the primary connection and switch back to the primary connection when connectivity is returned.

Configuring WAN/Cellular

Setup

AirLink Helix User Guide

switches to if the primary connection fails. Default primary interface is Ethernet.

4.If needed, change the Primary Route IP and interval.

5.Click on Apply and reboot the box when prompted.

6.Plug in the Ethernet cable for the WAN connection in to WAN/LAN port of the Helix.

How it works

When enabled, Helix will ping the Primary Route IP at the interval you have configured. If one of these pings fails, Helix will immediately send another short series of pings to that IP address. If these pings also fail, Helix will switch to using the secondary Internet connection.

While the secondary Internet connection is being used, Helix will continue to ping the Primary Route IP to determine when the connection is restored. When the connection is restored, Helix will switch back to the primary connection.

IP Passthrough

IP Passthrough mode will pass the cellular WAN IP address directly through to any client connected to WWAN/LAN port on the Helix. This may be necessary for some VPN configurations or other enterprise applications. The Helix can also continue to provide LAN IP addresses to clients connected through LAN port (or Wi-Fi with supported devices). However WAN Failover, DMZ, and Port Forwarding are not available and ACEmanager cannot be reached through port 1. Any client connected to WWAN/LAN port must be setup with a static IP address and a gateway address that matches the WWANIP address and gateway address. IP passthrough works best when the cellular module is setup by the cellular carrier to receive a public static IP address on the carrier network.

Figure 6-3: ACEmanager: WAN/Cellular - IP Passthrough

The LAN/WiFi section displays VLAN configuration parameters, in

ACEmanager.

VLAN stands for virtual LAN. VLANSs help structure the network growth of companies. A VLAN typically has a cluster of hosts that are together in a broadcast domain and not based on their physical location. A difference between VLAN and LAN is that a VLAN allows devices to be grouped together even when the devices are not located on the same network switch.

The VLAN implementation with a Helix is more of a VLAN support. i.e. if there is a switch behind the Helix that supports VLAN, Helix will forward the packet to the appropriate VLAN segment.

ACEmanager allows the users to reconfigure their network instead of relocating devices.

Addressing/VLAN

This section indicates the status and allows you to change the IP settings of the local network.

Note: Changing settings in this area will require you to reconnect to

ACEmanager after saving any changes.

AirLink Helix User Guide

WiFi Global

On supported models, the Helix has a Wi-Fi radio for wireless network connections.

Note: You can lock yourself out of the Helix when you first turn on WEP or WPA. You must then enter the right key in the format required by your computer or device before you can connect to the Helix with Wi-Fi. WEP and WPA do not affect Ethernet connections, so you can always connect to the Helix through an Ethernet port regardless of your encryption settings.

Configuring LAN/WiFi

AirLink Helix User Guide

Figure 7-4: ACEmanager: WiFi - WPA/WPA2 Personal

Configuring LAN/WiFi

WPA Enterprise

WPA Enterprise adds another layer of security to WPA by requiring clients authenticate with a server before being able to access the network. Clients connecting to the Helix when WPA Enterprise is enabled will need to have certificates installed from the RADIUS server, allowing them access to the network before being allowed to connect.

AirLink Helix User Guide

WiFi 2

The WiFi interface can support up to 4 WiFi LANs (WLAN), each with a separate

SSID, and separate encryption settings. Global settings apply to all WLANS.

Each WLAN may be routed to the Internet under user control.

Figure 7-6: ACEmanager: LAN/WiFi - WiFi 2

Global DNS

Global DNS allows you to override the default DNS settings of the cellular modem. This is used when custom cellular network settings (such as DataLink or custom APNs) are used on the cellular modem. Some carriers will block this setting. Check with your cellular carrier for more information.

Figure 7-7: ACEmanager: LAN/WiFi - Global DNS

AirLink Helix User Guide

The Helix Box can act as a Virtual Private Network (VPN) client, providing enterprise VPN access to any device connected to the Helix RT even when a device has no VPN client capability on its own. The Helix supports up to two tunneling protocols, IPsec and GRE. Both can be used at the same time if configured properly.

The Helix also supports split tunnels with one encrypted tunnel and one open tunnel. A sample server subnet for a split tunnel would be 172.16.1.0/24. Split tunnel VPNs should be setup with care, as a split tunnel configuration with both an enterprise VPN and access to the public Internet can inadvertently expose company resources.

This section should give you a general overview of the VPN capabilities. If you would like specific solution support, refer to the recommendations and instructions provided with your VPN server solution.
