Just got a Macbook running El Capitan. When it starts up after sleep, the internet is unavailable. I switch networks, get the link for Connection help, the whined appears and all lights are green. Then the web page loads.
it's a work around, but something's not right.
Any one have similar problems?
iMac (24-inch Early 2009), OS X Mavericks (10.9.3)
Hello edgework,
Thanks for using Apple Support Communities.
I understand your Mac isn't connecting to the internet after waking from sleep. To help troubleshoot this issue I suggest that you follow through the troubleshooting outlined below:
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.
- Check your TCP/IP settings in the Network pane of the System Preferences. Click the "Renew DHCP lease" button
- Choose System Preferences from the Apple menu.
- Choose Network from the View menu.
- Select Wi-Fi, then click the Advanced button in the lower-left hand corner of the screen.
- Click the TCP/IP tab from the top of the screen.
- Click the "Renew DHCP lease" button.
- Select the Wi-Fi tab and view your Preferred Networks list.
- Select each network and click the minus (-) sign to remove those networks from your Preferred Networks list.
- Click OK and close the Network preferences.
- Remove your stored network passwords using the Keychain Access Utility.
- Open Keychain Access from /Applications/Utilities. Your window will look like this:
- 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".
- 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.
- Restart your computer.
- Join your Wi-Fi network. You will need to enter your password for your network again if it requires one.
How to troubleshoot Wi-Fi connectivity in OS X Lion or earlier
Have a good one.
