Ubuntu server 12.04 wireless network card problems


Im very new to ubuntu linux here, what im trying to do is install ubuntu server on another pc i have here to share files. the installation goes well until i get to network configuration. when it gets to the point of searching for wireless networks it cant find any wireless network. i can skip this point and the installation will finish fine but i am still unable too connect to my wireless network.

you will need to specify your wireless card model. You can get that by issuing lspci or lsusb in terminal. Than you can also try to google your problem.

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.
