Dell inspiron 5110n - DRIVERS BUG!! ,.. Dell is the worthiest support ever !

hi , i bought dell inspiron 5110n i7 nviedia 500hd .. its the one iam using right now ..

the problem is ... dell
that is right .. i hated you ! .. i used to respect you guys before i bought that laptop !

to be honst the laptop works great ... the problem is ... Windows 7 ultimate Never! install the drivers by itself  .. i had to reinstall the windows after i bought the product and when i did .. i realized that windows never ever install any of the drivers by itself .. and dont blame windows 7 ... i never had problem installing drivers to any other laptop or desktop i ever used .

when i installed the drivers i had on my (HDD) that i found on my laptop .. i realized that the network , wifi & bluethooth .. are not installed .. i wasnt able to join the internet since the network card is not installed either >_< .. so i had to use external usb wifi to help me out .. and i downloaded all the supported drivers i found on dell-support website for my laptop and i tried to install them all ... but nothing happen ! 

i restarted the laptop .. re-installed the windows like 5 times that day ... nothing .. what the hell is that ?

spend the hole day  till 8am trying to find a way .. i found a program called ( driver idiniefier or something ) .. i used it .. and got me alot of driver ... nothing worked .. but when i upgrated the driver from driver manger to search the C:/driver folder .. it got the wifi inistalled 

but not the bluethooth nor the (Microsoft virtual wifi adapter)
 
---------------------------------------------------------------------
*Drivers that i wasnt able to inistall are :-
**********************************************
  -dell wireless 1702 802.11b/g/n ( its working now but i am not 100% sure how i make it work .. none of the dell drivers on dell worked )
  -dell wireless 1702 bluetooth v3.0+hs
  -Microsoft Virtual Wifi Miniport Adapter
 -------------------------------------------------------------------

 *things i have tried 
**********************
1) dell diagnosis   (( it is not working on chrome but working with Internet explore but with bugs ! .. never helped me with anything ))
2) drivers download for my laptop using support tag  (( didnt help with the 3 drivers i were looking for ))
3) re installing the windows  ( windows 7 ultimate ) (( didnt help .. same problem everytime ))
4) looking for drivers over the internet (( helped me findings wifi .. but iam not sure how.. i am also hav a good chance to find the rest but i have to download all the drivers that have same name which could take forever )) 

- right now .. i disabled the Bluethooth and the Virtual wifi so they dont get damaged or anything
