The name resolutions for wireless clients is disabled by default. It depends on your NPM version, but in the latest it can be enabled in \SolarWinds\Orion\Wireless\SolarWinds.Wireless.Collector.dll.config file. Change value for RDNSTimeout key (0 means RDNS is disabled, other values are seconds).
Thanks - that's a big help.
Do you know if this is applicable in release 11.5?
I don't see the RDNSTimeout key in \SolarWinds\Orion\Wireless\SolarWinds.Wireless.Collector.dll.config file.
I'm using NPM 11.5.2. I just enabled heat maps late last week and I am going through the same issue trying to add the hostnames to the client locations on the heat maps, but I'd like them to be shown elsewhere also. I made a copy of the config file, then added the line and restarted the web console as this link suggested, but so far I'm not seeing any DNS resolution for wireless clients in any location within Orion.
This is what the beginning of my config file looks like:
<?xml version="1.0" encoding="utf-8"?>
<section name="log4net" type="System.Configuration.IgnoreSectionHandler" />
<add key="ConvertToLocalTime" value="True" />
<add key="WirelessPollingJobTimeout" value="10" />
<add key="SaveRoguesToHistory" value="True" />
<add key="UseHostNamesInEvents" value="False" />
<add key="RemoveDisappearedAPs" value="True" />
<add key="UseNPMPollerDAL" value="False" />
<add key="RDNSTimeout" value="1" />
I also found this link regarding the DNS cache timeout, I'll change it and see what happens.
Edit: Still doesn't work anywhere for me.
