Do you have Broadcom WLAN? If so, you would need to install drivers.

You will have to download the driver depends upon the WLAN hardware. What is your WLAN hardware? Check with lspci command

lspci -v

If you have internet access to your linux mint, try the following command,

This won't work, the lspci output indicates that it is an LP-PHY, so you need to install a different firmware
Code:
sudo apt-get install firmware-b43-lpphy-installer
You need a wired connection to do this.

these commands are to help us to know what your system thinks is installed (not necessarily to get you connected).
Code:
lspci # will tell us the pci devices you have in your system.
lsusb # will tell us the usb devices you have in your system.
ifconfig # will tell us what network interface cards you have turned on in your system.
ifconfig -a # will tell us all the network interface cards you have in your system.
iwconfig # will tell us which of your network interface cards has wireless capability
now that we know that, this should get you connected:
Code:
sudo iwlist device scan # this will use the device interface (that from the above command, we found out has wireless capability) and scan for wireless routers that are accessible.
sudo iwconfig device essid "myssid" # assuming no security, use that device to connect to your router.
sudo dhclient # will attempt to get ip-address, subnet mask, dns server information automatically from your router assuming dhcp is turned on on your router.
also, please post the contents of cat /etc/network/interfaces
and /etc/resolv.conf should contain your dns server.
depending on if ifconfig returns the name of your device, you mite need to turn it on by doing something like: sudo ifconfig device up
you can also run lsmod to see if the wireless driver module is plugged-in.

^ sigh, paste this into a terminal window:
Code:
echo uname: && uname -a -m -p && echo lspci: && lspci && echo lsusb: && lsusb && echo lsmod: && lsmod && echo ifconfig: && ifconfig && echo ifconfig -a: && ifconfig -a && echo iwconfig: && iwconfig && echo resolv.conf: && cat /etc/resolv.conf && echo route: && route -n
then highlight the result, rite-clik->copy, then paste it into your next response to us. that way we can determine the card model and manufacturer and someone could let you know what driver to use if one exists.
