Have router ASUS 4G-AC55U and lost 5 GHz WiFi on X6; FW 1.0.27. Ethernet and 2GHz working ok. 5GHz working on iPad and two Tronsmart Orion R28 Meta, so no router problem! What to do?
My X6 Pro does not see the 5Ghz band, no matter how much I fiddle with the router settings (cycling through all channels and setting 20MHz and 40MHz bandwidth). All my other Android, iPhone and MBP devices can easily connect to my 5Ghz band and to my neighbours' 5GHz band as well. The X6 Pro does not even see them at all. How can one enable 5GHz support on the X6 Pro? The 2.4 GHz is so slow, that I can only watch low-bitrate encoded 720p on the TV. The box is rather useless in my case like that.
