Poor Wireless Network Connection

ACE manager indicates that my AirLink gateway has a poor wireless
connection. What can I do to improve it?
For GSM or CDMA networks:
1. Check the RSSI value. If ACEmanager (Status screen) indicates a good RSSI
value, go to step 2. If it indicates a poor RSSI value:
· 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 gateway to a new location.
2. Check the Ec/Io value. If ACEmanager (Status screen) indicates a poor Ec/Io
value:
· This may be a temporary network problem caused by local interference.
· A nearby laptop or other electronic equipment may be interfering with the
signal. Try moving the AirLink gateway to a different location.
For LTE networks:
1. Check the RSSI value. If ACEmanager (Status screen) indicates a good RSSI
value, go to step 2. If it indicates a poor RSSI value:
· Check the antenna connection.
· Make sure you have the correct antenna for the device.
· Try moving the AirLink gateway to a different location.
2. Check the RSRP value. If ACEmanager (Status screen) indicates a good
RSRP value, go to step 3. If it indicates a poor RSRP value:
· This may be a temporary network problem caused by local interference.
· 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 gateway to a new location.

signal. Try moving the AirLink gateway to a different location.
