4 Troubleshooting
This chapter displays the common problems that can occur while setting up a
bridge link. If your problem is not related to any of the below mentioned problems
please contact your reseller.
Problem: No connection between the networks
If the radio LED of the client is not blinking:
•
Make sure both bridges are powered up.
•
Make sure the bridges are within the valid range for the antennas.
•
Make sure that the channel settings for both bridges are the same.
•
Make sure that the antenna is connected or cable is not broken.
•
Make sure that the antennas are in line of sight (NO obstacles!).
•
Make sure no other device is transmitting on the same frequency. You can
do this by changing the frequency settings on both bridge units.
•
Bring the ED threshold down.
If the radio LED of the client is blinking or the Bridge Monitor’s signal strength
indicator (on the Tuning screen) shows a good signal):
•
Make sure that the SSID/ESSID of all bridge units is exactly the same.
Problem: Can not access the bridge settings via network
•
Check if sub-net mask and default gateway is set according the network
the bridge is connected to. (To do this you need to connect directly to the
unit)
•
Check if the unit has been reassigned another IP address. (To do this you
need to connect directly to the unit.)
Problem: Low throughput on the link
•
Check if the average of SQ2 is below 10. (Go to monitor screen in the
Bridge Configuration program.)
•
Check if the ACK time fits the range.
•
Check if the network card of the PC you are measuring with can handle
the throughput.
Problem: Link drops off every now and then
•
Check the antenna alignment
•
Check the line of sight for obstacles
•
Check
antenna
mounting
•
Check if ED threshold is set to 99, if not do so.
