I have a couple of RB711 boards with integrated antenna in the 5 Ghz band. when i try to estabilish a connection i get a tx / rx signal of -66/-88 on one unit and -68/-69 on the other. How is this possible? what can i check??

thanks in advance

the one unit with the bad receive signal might be defective, try to swap for a new one, or ask seller for inspection/replacement
