We are sorry to learn that. Is your computer a laptop and your Intel(R) Centrino(R) Wireless-N 2230 the original card that came installed in your computer when you bought it? If so, our first recommendation is for you to contact your computer manufacturer to see if they have any driver updates for your wireless and Bluetooth card. Once you have done that, the next step is to see if your firewall and antivirus configuration is impacting your connection as sometimes, depending on the kind of configuration done my cause this kind of problems. If it is necessary to temporarily uninstall the antivirus to test your connection, please do so.
Also, check if your router has the latest firmware and if not, please try to update it. Here are some links with information that might help you resolve your issue.

i can't believe myself omg man thank you thank you every thing is working perfectly ^_^
the problem wasn't my antivirus it was a registry problem i'll tell what i have did to solve the problem:
1-updated my wifi and bluetooth from my manufacturer company (DELL) and other drivers and my BIOS ( i don't think the updates are important)
2- opened services.msc and set the network location awareness to automatic (delayed start) and start it
3- opened the regedit (register editor) and navigated to HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\NetworkList
4- deleted the profile content and signatures content
5-restarted my laptop
6- followed this replay from Network and Sharing Center shows not connected, but computer is - Microsoft Community :
Confirmed changing registry permissions resolved my issue.
Short version, go to regedit, navigate to HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\NetworkList
Change permissions on NetworkList, (click advanced, add Local Service and Network Service with full control, check the box to propagate permissions to all child objects).
Reboot and boom fixed.
7- and it worked ^_^
