Thank you Mike for getting back so fast.
It isn't that the laptop is not connecting to the net at all times, just that at sometimes, it gives a hard time connecting, more so when I am at work, where all other friends are being hooked to the wifi and my laptop does not even show the signals. Since other periperals are working under the same wifi, it does not prove useful asking back at office to switch off the router, reset and all, you can guess the obvious, all other people for whom it is working normally may be mad at me for cutting off the net connections....
Since it is something that happens at times only, while other laptops and phones are still wonderfully connected and enjoying internet, just then my laptop seems to malfunction, at times not showing any wifi signals in range and not even taking connections from LAN wires.
I know it sounds quite weird, thats must be the same reason why I could not search for its options online.
Thank you again
