Macbook Pro - Wifi not connecting, no network found.

Since past few days my Wifi on the Macbook fails to find any network so I cannot connect to internet.

My other devices such as Iphone, Ipad find the netwrok and work perfect.

I try to join other network with the same name and password but cannot connect.

Had no problems for years with the wifi connection before.

Please take all the following steps that you haven't already tried. Stop when the problem is resolved. Back up all data before making any changes.

Step 1

Take the applicable steps in this support article. The Wireless Diagnostics program generates a large file of information about your system, which would be used by Apple Engineering in case of a support incident. Don't post the contents here.

Step 2

Run Software Update and install all available updates for OS X or your computer's firmware.

Step 3

If you're not using a wireless keyboard or trackpad, disable Bluetooth by selecting Turn Bluetooth Off from the menu with the Bluetooth icon. If you don't have that menu, open the Bluetooth preference pane in System Preferences and check the box marked Show Bluetooth in menu bar. Test. If you find that Wi-Fi works better with Bluetooth disabled, you should use the 5 GHz Wi-Fi band. Your router may not support it; in that case, you need a new router.

Step 4

Open the Network pane in System Preferences and make a note of your settings in the Wi-Fi service. It may be helpful to take screenshots of the various tabs in the preference pane. If the preference pane is locked, unlock it by clicking the padlock icon and entering your administrator password. Delete Wi-Fi from the service list on the left by selecting it and clicking the minus-sign button at the bottom. Then recreate the service by clicking the plus-sign button and following the prompts.

Step 5


Reset the System Management Controller.

Step 6

Make a "Genius" appointment at an Apple Store, or go to another authorized service center.
