and greetings from Finland, Europe. I've been a linux user for past 12 years, and decided to switch to Elementary when I bought recently a used Elite HP G2 Laptop, tried around 6 different distros with the same problem, the system does recognize that I have a wlan adapter, but finds no access points although they are there. This seems to be a problem related to BroadCom drivers. I have Broadcom Wireless Adapter BCM4352 802.11ac PCID [14e4:43b1] (rev 03)

Propriety drivers that the system offers do not work and this particular model seems to be unable to to handle the most commonly appeared bcwl-source solutions.

So my question is how to get the wifi to find access points on this systems. After all, there has to be a way.

Here are all the information that I suppose is needed to diagnose and provide a proper solution. I would like to thank anyone for help in advance because this DOES beat me. All the help is highly appreciated. Thank You.
