So, my Asus K55VM laptop has been unable to connect to wireless networks from distance. At best it gets connected to the networks as long as the source is less than 2 meters away. Any further than that, the signal is deteriorating to Zero. One of my antenna cable got broken earlier, so I just interchanged it with other white antenna and it was working fine. I checked the other antenna cable and it is still fine. Now, is there any way to know that whether the problem lies in my wi fi network card or the antenna cable. In the device manager, it is showing to be 'the device is working fine'.
