My Samsung Galaxy Note II [GT-N7100] Wi-Fi range is dropped, it will not connect to my wifi router while i moving from one room to another room and also while i sending files through Xender or Zapya i got full speed only while i keep both devices back to back, and the same thing happening while i turn on WiFi Tethering. my question is that is it my Note II’s wifi hardware issue, if then can i replace that module ?
