How do I install Realtek firmware for wireless?

I just reinstalled Kali but now I can't connect to my wireless router.
Wicd network manager says there are no wireless networks found.
And iwconfig shows this:

Can someone please give me a simple solution to make my Wi-Fi work? I downloaded the firmware files but I can't install it.

Thanks in advance.

If I am not mistake - eth0 is lan not wlan

Do you need a firmware? For which card?
