I second this suggestion. Your skill level is not nearly sufficient for this 
sort of task. Note that there is a group working on driver rtl8192su, which 
should be able to replace rtl8712u. The participants are very highly skilled 
wireless developers; however, they are having trouble. The internals of the 
Realtek chips are not revealed to anyone in any form other than the code they 
release.
