when i enter into my bios , i didnt find any network reset option inside it

Not every motherboard manufacturer supports It, hence It may be the case with yours.

That said, do you have a "Power Management" option? If so, see If there's anything related to "Wireless".

now i found service center also and i filled the online repair form.

Good.

This should've been done a while back.

i just found that my wifi card is located below the hard drive , damm fuck , i am scared .now.. that they dont do any damage to hard drive. , replacing wifi wiill they keep the laptop , or will quickly return to me in few hours.....
