I have two routerboards, RB 532A and RB 411...the RB 532A is acting as a hotspot server and the RB 411 is just a hotspot AP...but these two are connected via the STP cable on the tower, but the the problems is...when you go ip neighbor you cant see the other router (RB411) but on the RB 532A interface....you get link ok...and when you run bandwidth test between the two routers the max you can go is 2M and clients cant get the required speed....and...some ports shows on and off....I have tried to change the boards but still when you get it there on the tower...it still functions the same.. when you take the boards down the tower the ethernet interface works fine...please assist...
