So my 88u suddenly dropped all 5ghz devices, none could reconnect. The 5ghz light is a solid white, no flickering. Site surveys from any device CAN see the ssid, but can't connect. I have tried factory reset, numerous firmware versions (official as well as Merlin), all the usual recommended "disable this enable that, set channel blah" and so on. I saw in another thread Merlin mention something about checking wireless log to see if the radio shows a channel number or if it says 0. It definately shows a channel number, in fact whichever channel I set it to it shows. Noise: -82 dbm Channel: 149/80. Is it even possible that the transmitter is working fine but the receiver has died? If so is there some way I can find out for 100% certain, like some diagnostic log or something? Unit is a year outside of its warranty.
