Hi, yesterday i got my three deco m4, they are in AP mode, and they are connected by ethernet cable. I have a problem with them, speed on 2,4Ghz is very slow, 10mb/20mb at max. i have disabled the 2,4ghz band and on 5ghz it is working great, about 300 mb/s, but when i connect through 2,4ghz band the speed drops. Can you help me? i thinking about refunding them because of that
