I bought my Sony XZ2 3 days ago brand new. From the first day I had trouble with it not showing my 5GHz Wi-Fi signal, it appears for like 20 to 30 seconds when I restart the phone but then it goes away... I also tried to restart the router but nothing either.
The 2,4 GHz is working fine but I need the 5 GHz.
The router transmit both bands, all the other devices see the 5GHz but not my Sony Xperia XZ2.
Please help.
