I have just installed ubuntu 12.04 and i am new to this operating system. i have a dual boot with window 7. My internet connection speed is very good in windows 7, when i test using it reaches a speed of around 10MBPS but where as in ubuntu it shows some were between 1-1.5 MBPS. this is the same either i connect by wifi or lan. i have installed all the packages like ubuntu extras.

i request if some one can shower some light on this query, i really want to get this done. This is the wifi adapter : RTL8188CE
