Wireless internet does not work in Ubuntu

hey..

i am quite new in Linux, so my skills and knowlegde about Linux isn't wide.. yet ;)

well.. i have a problem with my wireless networking in Ubuntu.. i have all the drivers installed for my network card, Atheros.. but it can't find any wireless networks in Linux, but in Vista or XP there is a lot..

I have tried everything i can get up to, but nothing works!! when i try to PING, there is no problems..

the last thing i did was this:

johnny@johnny-laptop:~$ sudo iwconfig
lo no wireless extensions.

eth0 no wireless extensions.

johnny@johnny-laptop:~$ sudo ifconfig
eth0 Link encap:Ethernet HWaddr 00:03:0d:9c:ee:2d

well.. i just found out by Fujitsu siemens support center, THAT my wireless LAN card is INTEL!!! very confusing, cause in the manual it says ATHEROS!

i really don't know what to do!! PLEASE HELP!

It may be an intel card with an ATHEROS chip. You say you have all the drivers installed for the card. I presume you are talking about native linux drivers. I think you do not have the right driver installed.

now i have tried madwifi, ndiswrapper, ipw,ar5007 drivers, evrything!!! both on the build en network manager and wicd.. NOTHING works!

Try this - it worked for me!!

I had endless trouble getting WiFi to work on Ubuntu - finally this post worked, although I tried it several times - I needed to clear out the old drivers first.

It is important to foollow the procedures very carefully - particularly in checking/unchecking the Hardware Drivers in System Administartion.

Good Luck
