USB wireless adapter that works on my ubuntu 10.04 (DLINK dwa-125)

Hi there~ i ve been trying to setup usb wireless TP wn821n . but i failed. So i try on DLINK DWA 125 . so far so good. i just installed today.

if you want to install too.. you may refer this tutorial

thanks for the one who posted tutorial on youtube..:) , after you have installed.. you can plug in your dwa usb. and you can see it start to blink. after that you will notice that the internet connection is slow..
what you can do is open your terminal, then write the following command.

iwconfig eth0 rate auto

The etho part you can change to your driver name .. you can know by typing 

iwconfig

for more detail please refer here ----> http://manpages.ubuntu.com/manpages/hardy/man8/iwconfig.8.html 

under the rate/bit section :)  

k THATs all ..enjoy your internet connection now :)
