Radio Manager FAQs and Troubleshooting

You use Assisted Site Survey to generate your power settings and apply the following power settings (respectively):

{5,10,20,5}

AP C goes down and Self Healing adjusts the power settings:

{5,20,down,20}

AP C comes back up and Self Healing adjusts the power settings:

{10,5,20,5}

In the final state, this is an equivalent coverage—perhaps not the exact settings, but equivalent.

When you set the power manually and do not use WLSE to calculate the initial coverage: You manually set the power setting to:

{10,10,10,10}

AP C goes down and Self Healing adjusts the power settings: {5,20,down,20}

AP C comes back up and Self Healing adjusts the power settings: {10,5,20,5}

Self Healing uses the WLSE recommended settings when the AP comes back up, not the manual settings. WLSE is not designed to save check point configurations as part of the management.

Note All Self Healing power settings are temporary, so any reload of the APs will revert to the last saved configuration on the AP itself.

Q.I am seeing warning messages in the self healing run log. What do they mean?

A.These messages are warnings—not errors, faults, or actionable items. There are two types of warning messages:

Dot11Radio0[MACADDRESS]@IPADDRESS

Does not have any reliable vouchers within range or configuraton

For the given radio there are no other radios that have an acceptable path loss or configuration to vouch for the monitored radio. To determine if a radio is transmitting, at least one other radio in the deployment must be able to reliably hear the monitored radio’s beacons. In that case, the monitoring for the radios in question will rely solely on the WDS/Registration that is maintained over the AP’s Ethernet connection (that is, not wirelessly).

The determination of a reliable voucher for a monitored radio is made based upon RSSI/Path Loss and basic rate sets. Keep in mind, however, that the data rates configured on a radio are not necessarily the same as the basic rate sets (beacon data rates).

The following reports in Reports > Radio Manager can help you here:

Configured Radio Parameters Report

Path Loss between Manager APs Report

By looking at the path loss and configured data rates between APs you can see if the radio in question has any acceptable radios in range.

WARNING: Dot11Radio1[MACADDRESS/BAND]@IPADDRESS

has excessive links to other radios which may make this radio appear stale

(undetectable beacons), total = XX
