I'm having some issues with the last release of Lubuntu on my old pc (ACER TravelMate 2702WLMi). The main problem is that i cannot connect to any wifi line. In the network panel in the application bar i can only see Ethernet Network, while there's no Wifi connections. I've searched through some forums and the only post that seemed to correspond to my problem is this one Installing Broadcom Wireless Drivers The problem is that probably i don't have a broadcom driver but a realtek one, but i'm not sure about it. the only think about i'm sure is that the guide is the solution for my problem if i only had a broadcom driver because i've the exactly same problems.
What can i do to discover my wireless drivers and how to install them correctly on Lubuntu to make wifi work?
I'm a user with no advance knowledge in Linux, so I would need clear explanations on how to make, compile, etc.
