LINK IS UNRELIABLE OR DOES NOT ACHIEVE DATA RATES REQUIRED
If there is some activity but the link is unreliable or does not achieve the data rates required,
proceed as follows:
Procedure:
1 Check that the interference has not increased by monitoring the uplink and downlink CINR
values reported in the AP page Monitor, Wireless Status
2 Check that the RSSI values reported at the AP an SM are proper based on the distance of the
link – see
Table 125 on page 426 and Table 126 on page 427.
3 Check that the path loss is low enough for the communication rates required.
4 Check that the AP or SM has not become misaligned.
5 Review your Quality of Service configuration and ensure that traffic is properly classified and
prioritized.
MODULE HAS LOST OR DOES NOT GAIN GPS SYNCHRONIZATION
To troubleshoot a loss of sync, perform the following steps.
Procedure:
1 If the AP is receiving synchronization via CMM, verify that the CMM is properly receiving sync
via its attached GPS antenna (see
PMP Synchronization Solutions User Guide ). Verify that the
cables from the CMM to the network switch are at most 30 Ft (shielded) or 10 Ft (unshielded)
and that the network switch is not PoE (802.3af) capable.
2 If the CMM is receiving GPS synchronization pulses, verify that the AP’s Synchronization
Source is set to CMM and that the AP’s GPS status bar icon is lit green.
3 If the AP is receiving synchronization via its internal GPS module and an external GPS
antenna, verify the cabling from the AP to the GPS antenna, and verify that the AP’s
Synchronization Source is set to GPS.
