The wireless radio on my Archer C6 AC1200 doesn't work. I tried resetting multiple times, changing firmwares. I cannot enable wireless radio from the web UI, because it says to turn on using the wifi button. I tried the wifi button and it doesn't work. The wifi bulbs don't turn on not matter how many times I press and hold the wifi button. The bulbs are working. They switch on during reset. But the wifi doesn't turn on. And also, when switching the operation mode to access point, it reboots and again switches to normal. Help me.
