Hi guys. I have one question.. I own Lenovo Zuk Z2 Pro and it has Snapdragon 820 and it supports Wifi AC but somehow it does not detect 5 GHz band.. the funny thing is even my old Samsung Tablet detects and connects it. My notebook also connected to same Wifi band. Does anyone had a similar issue or anyone knows what could be the reason ?

Try to change the Channel Width to 20mhz and the actual Channel. Some lower end AC WiFi chips are very sensitive to the width and frequency of the channel.
