Friends
I have got a new USB wifi adapter of Netgear with Realtek Chipset. I am using UBuntu 12.04. I tried to install it according to the directions in Ubuntu forums. But I failed. Can anyone please help me out. I am a newbie in Ubuntu.
Below are some of the commands I ran.

I need to connect a wi-fi adapter to a development board with Linux. The board alredy has ethernet conector that works right, but doesn't have wi-fi. So I connected an wi-fi adapter to a USB port, and now I need to redirect internally the input/output from ethernet to the USB port. How can I do that?

grepping the device Id will never return anything from lsmod, as it shows the modules name

If it not has changed inbetween, you should have the file
/lib/firmware/RTL8192SU/rtl8192sfw.bin

It looks like no firmware has been loaded.

Can you post the result of :

Code:

dmesg

(maybe cut off the no relavant parts)

and

Code:

ifconfig

This has been solved by loading the driver of realtek from realtek site
