Hi there, 

I have an OC200 connected to 6 x SG2008 Switches, 1 x SG2218 Switch and 3 x EAP610. When I go to Map > Topology, it says no devices found.

The devices are, of course, connected and show up in the devices section. 

This has worked for a long time up until now, but suddenly stopped working. I spoke to my brother who said he might have changed a setting 'root device' or something on the Topology page - could this be the issue? I now cannot find any way to change that setting back so that my topology re-populates as it was before - is there any way to revert this setting? (if indeed that is the cause!)

Thanks,
