Hi! I have just read "as well as some Ubiquiti 5ghz bridges, connected by ethernet pigtails to the TP-Link’s switch. All of the routing is done by Libre-Mesh running on the TP- Links: The Ubiquitis are dumb wireless bridges." http://blog.altermundi.net/article/libre-meshing-paravachasca-valley/ Are you using lime-hwd-ground-routing? I ask because it is done for this type of things. Cheers!
