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. For additional help
connecting your computer or device to the AirLink Helix, please refer to the
networking instructions provided by your computer’s operating system.
Please contact Sierra Wireless support for further Helix RT related queries.
