Hello 

 

I have a dell laptop "Inspiron 5558" . For last, about 2 months, the wifi range in the laptop is not coming full as it used to, it just shows one dot range and doesn't even detect near about networks many times. 

 

Please lend me a hand, fixing it.

As the amount of dust builds up internally, it will reduce the range of the tiny WIFI antenna built into the WIFI chip assembly.  There may be other factors external to the laptop or router that will degrade the signal strength.

Hey, Thanks 

Actually,the problem is not in Router because other devises do catch the range very well.

Besides that the network works very good when I access internet via lan cable directly.

 

Now do I have to clean it up if the case is of dust building up? Or is there any program that I can run which can help me identify if it is internal process or external?

You can try a can of compressed air, first blow into the exhaust port.  Then blow into any other openings, if ho improvement it needs to be opened up.  Put your make and model into a YouTube search, opening most up is pretty straight forward.
