· Check the antenna connection.
· Make sure you have the correct antenna for the device.
· You may be in an area with poor coverage. Check with your Mobile Network
Operator, or if possible, try moving the AirLink device to a new location.
3. Check the RSRQ value. If ACEmanager (Status screen) indicates a poor
RSRQ value:
· A nearby laptop or other electronic equipment may be interfering with the
signal. Try moving the AirLink device to a different location.

Connection not working

My device appears to be connected to the host, but no data is being
transferred.
1. Check to see if MAC filtering is enabled (Security > MAC Filtering).
2. If MAC filtering is enabled:
• Ensure that the MAC Address for the host in question is on the Allowed List.
• Ensure that there are no typos in the MAC Address.
Or
• If it is not required, disable MAC Filtering and reboot the device.
My host device is unable to connect to the Internet, even when there
is good cellular network coverage and ALEOS can Ping an external
IP address.
1. Check the DNS proxy setting described on
You may need to change this setting to Disable so that all connected hosts
acquire the Mobile Network Operator-defined DNS server as the first DNS
server. The AirLink device is not used as the DNS resolver.
Updating the ALEOS Software and Radio
Module Firmware
I am unable to update the ALEOS software and radio module
firmware using ACEmanager.
If you are having trouble updating the ALEOS software or radio module firmware,
especially if you are updating from an older version of ALEOS:
1. Try using a different browser. (ACEmanager supports the latest versions of
Internet Explorer and Firefox.)
2. Delete the browser cookies/cache before logging into ACEmanager. (The
Web browser short-cut is Control + Shift + Delete.)
3. Backup your device settings by downloading and saving the template. See
Saving a Custom Configuration as a Template
4. Reset the device to factory default settings. (See
page 240 or press and hold the reset button on the device for 7 to 10
seconds.)
