I have a Le 2 pro x620 and as per specifications, it should have 2.4Ghz and 5Ghz AC wifi but mine is not connecting to a Xiaomi WiFi Mini on the 5Ghz AC . I also have a Asus zenfone 2 ZE551ML and my Laptop connecting perfectly on both 2.4 and 5 Ghz. I have searched for a setting to enable 2.4Ghz and 5Ghz but there is none. So does it support 5Ghz?
