My friend gave me this laptop to use for my university. It's a Samsung NP-X420 which has Lubuntu 14.04. The problem is that I don't know how to get wifi on this laptop. This is what I see: Desktop Lubuntu.
I started to search around in the laptop and then I clicked on: Preferences > Network Connections. When I click on "Add", I get this window where I need to choose the Connection Type. Then I click on "Wi-Fi" and then "Create". Then I get this window: Wi-Fi and I don't know what to do. Like, do I really have to fill in all the parameters of the wifi network that I want to connect to? How would I know them, especially if I want to use the wifi of my university?
I'm not sure what to do to get wifi. Do I need to install drivers? Do I have to use some command in the terminal?
I don't have a wired connection at home, so I can't connect the laptop to the internet. I also don't have any boot CD/USB/etc... But I do have another (very slow) laptop at home that can connect to wifi and that I can use to download the needed drivers, and then put them on a USB stick to get them to the Samsung laptop.
I'm not so experienced with pc's, laptops and such so I would highly appreciate it if you are easy to understand and don't use too much technical terms. If there are some terms that I don't understand, I will of course do the effort to look them up on the internet, but please don't make me read several articles just to understand the meaning of a word. Thanks in advance!
EDIT: When I open the terminal and type: lspci -nnk | grep 0280 -A2
I get the following message:
02:00.0 Network controller [0280]: Broadcom Corporation BCM4311 802.11b/g WLAN [14e4:4311] (rev 01)
Subsystem: AMBIT Microsystem Corp. Device [1468:0422]
Kernel driver in use: b43-pci-bridge
The number 0280 between the brackets on the first line is in red color. I wanted to post a picture of it but I apparently can't post more than two images, since I don't have 10 reputations.
lspci -nnk | grep 0280 -A2
That funny pipe symbol | is on the right side of my US keyboard on the same key with \. Please edit your question to add the result. Welcome to Ask Ubuntu.
