i do tried all that already.. keep on releasing and renewing my ip address using dos command.. yet.. limited connection still.. my pc is also tired of restarting.. and i do all necesary troubleshooting always.. the cables.. the powersupply etcetera.. it goes on the same limited connection problem.. but when i install a fresh copy or retrieve my os mirror files.. my connection working again.. the question is that why the tweak isnt working for me. im using windows xp sp 2 and in fact is genuine.. i believe and i can feel that the values on the registry are incorrect thats why everytime i do the 20 steps and restart my pc turns my net unusable. i have tried the 20 steps correctly and precisely 4 to 5 times now and ofcourse.. i do fresh copy after the fail tweak.
