I have 4 R310's deployed via ethernet inside my house. I have really poor coverage outside the house and I need to deploy a R510 with antenna but there is no ethernet connection available outside unfortunately. Can I bridge/attach the R510 with the unleashed R310 inside the house or will I have to run a cable outside?
R310 do not support mesh. you will need to add at least 2 x R510 to have mesh, one inside connected to cable and one outside meshing to the first one. R510 are indoor units, depending on the temperature and humidity in your area, I would suggest to run a cable and put something like T310c.
