Yes I know L3 does not allow to set ap.
I have 7 pieces Groove 52HPn(level 3), when I try connect Groove 52HPn(level 3) as a client to RB951Ui-2HnD(level 4), no result- impossible, Groove blocking and I cannot login in Groove with Winbox and generate autosupout.rif file.
In the same time, if I connect the same router Groove 52HPn(level 3) with the same settings as a client to RB2011UAS-2hNd (level 5) or to linksys 54gl working perfectly.
I placed another RB951Ui-2HnD(level 4) in bridge mode as a client to another RB951Ui-2HnD(level 4) while to find solution. Distance is 250 meters.
May be no way for Groove 52HPn(level 3) to work as wifi client to RB951Ui-2HnD(level 4) !?
