WIFI connection

WIFI connection is so poor. It could detect the wifi of my neighbour but problem starts when I try to connect with any wifi connect. My router is sitting in my next room but it fails to establish connect unless I take my laptop near my router. Drivers are installed. Then what is the problem. I tried with phone hotspots also but the results are same.
My system information are here-
