Linux – Connecting Linux Mint to WiFi network

linuxlinux-mintwifi

I just installed Linux Mint 17 (MATE) on an old laptop and everything works amazing, however I can't seem to get it to connect to my WiFi network. All my other computers can get access, plus, before when the laptop has Windows XP, it could also find and connect. Is there a way to check if it's even detecting the correct network? If so, how would I set up a proper connection to the network?

There is nothing wrong with my network nor the laptop, so it must be Mint's fault.

Edit:
Output of iwconfig:

lo       no wireless extensions.

eth0     no wireless extensions.

Output of lspci -nn | grep 0280:

02:04.0 Network controller [0280]: Broadcom Corporation BCM4318 [AirForce One 54g] 802.11g Wireless LAN Controller [14e4:4318] (rev 02)

This answer assumes that you can connect your machine to the network using a cable and so get internet access. If that assumption is wrong, let me know and I'll modify this.

You need to install the driver for your wireless card. The driver support table of the Linux Wireless page lists it as supported so you should be able to get everything working by simply running:

sudo apt-get install firmware-b43-installer

If this does not work leave me a comment, you might need to tweak it a bit.
