Old Sony Vaio laptop doesn't wifi after installation

**tackskull** · August 21st, 2018

Hi there

A friend of mine asked me to install Linux Mint on his Sony Vaio laptop (a six/seven years old laptop). So I am not new with this operative system in fact linux mint is working fine on my own laptop and the wi-fi is working well.

The problem is that in this Sony Vaio (I can't tell you the model that is not write on it) after a fine Mint installation doesn't see any wifi network without getting acces to the internet. Connecting via cable the internet is going ok if fact I am writing you from this pc. I have enabled the broacom driver from the driver manager app but nothiing change. I tryed to see if there is any kind of physic switch to enable the wifi but nothing. I am not able to see any wifi from this pc.
