Appendix A: Troubleshooting
Check the following items before you contact local Technical Support.
1. If wireless bridge units do not associate with each other, check the following:
• Check the power injector LED for each bridge unit to be sure that power is
being supplied
• Be sure that antennas in the link are properly aligned.
• Be sure that channel settings match on all bridges
• If encryption is enabled, ensure that all bridge links are configured with the
same encryption keys.
2. If you experience poor performance (high packet loss rate) over the wireless
bridge link:
• Check that the range of the link is within the limits for the antennas used.
• Be sure that antennas in the link are properly aligned.
• Check that there is an unobstructed radio line-of-sight between the antennas.
• Be sure there is no interference from other radio sources. Try setting the
bridge link to another radio channel.
• Be sure there is no other radio transmitter too close to either antenna. If
necessary, move the antennas to another location.
3. If the wireless bridge cannot be configured using Telnet, a web browser, or
SNMP software:
• Be sure to have configured the wireless bridge with a valid IP address, subnet
mask and default gateway.
• Check that you have a valid network connection to the wireless bridge and
that the Ethernet port or the wireless interface has not been disabled.
• If you are connecting to the wireless bridge through the wired Ethernet
interface, check the network cabling between the management station and the
wireless bridge.
• If you cannot connect using Telnet, you may have exceeded the maximum
number of concurrent Telnet sessions permitted (i.e, four sessions). Try
connecting again at a later time.
4. If all other recovery measures fail, and the wireless bridge is still not functioning
properly, take any of these steps:
• Reset the wireless bridge’s hardware using the CLI, web interface, or through
a power reset.
• Reset the wireless bridge to its default configuration.
