Q: Very slow in finding wireless networks

SInce few weeks my MacBook Pro retina is very slow in finding the available wireless networks and listing them after waking up from sleep.

This happens also at my office and my home, with known and subscribed networks.

It can take up to one minute.

I tried to reduce the number of the preferred networks, but it didn't help.

 

Anybody had the same problem?

MacBook Pro with Retina display, OS X Mavericks (10.9.3)

    Hey ferrocinque,

     

     

    Thanks for the question. I understand that you are experiencing Wi-Fi issues with your MacBook Pro. I can understand how frustrating these issue may be. The following resource provides troubleshooting steps that may assist you:

     

    Wi-Fi: How to troubleshoot Wi-Fi connectivity

    Symptom: After restarting or waking from sleep, my computer might not connect to the Internet

    - After waking from sleep or starting up, your computer may not show that it is connected to a Wi-Fi network.

    - After start or wake, your computer may indicate that it is connected to a network, but does not connect to the Internet.

     

     

    Solution

    Use these steps if your computer does not automatically connect to your desired Wi-Fi network.

     

    1. Check your TCP/IP settings in the Network pane of the System Preferences. Click the "Renew DHCP lease" button

              a. Choose System Preferences from the Apple menu.

              b. Choose Network from the View menu.

              c. Select Wi-Fi, then click the Advanced button in the lower-left hand corner of the screen.

              d. Click the TCP/IP tab from the top of the screen.

              e. Click the "Renew DHCP lease" button.

    2. Select the Wi-Fi tab and view your Preferred Networks list.

              a. Select each network and click the minus sign to remove those networks from your Preferred Networks list.

              b. Click OK and close the Network preferences.

    3. Remove your stored network passwords using the Keychain Access Utility.

     

              1. Open Keychain Access from /Applications/Utilities. Your window will look like this:

              2. Remove your AirPort network passwords from the login keychain: Select the "login" keychain from the Keychain sidebar. Click the "Kind" column to order the list of keychain items by their type. Remove all entries of the kind: "AirPort network password".

     

              3. Remove your AirPort network passwords from the System keychain: Select the "System" keychain from the Keychain sidebar. Click the "Kind" column to order the list of keychain items by their type. Remove all entries of the kind: "AirPort network password".

     

              Note: The above steps will remove your Wi-Fi network passwords. If you do not know them, or if your network does not use passwords to restrict access, you should contact your network administrator.

     

              4. Restart your computer.

     

              5. Join your Wi-Fi network. You will need to enter your password for your network again if it requires one.

     

    Thanks,
