    Hi DL79,

    Welcome to the Support Communities! The resource below provides some troubleshooting steps for Wi-Fi connectivity.

    Wi-Fi: How to troubleshoot Wi-Fi connectivity - Apple Support
    http://support.apple.com/en-us/HT202222

     

     

    1. Restart your network devices.
      • Powering your modem or router off for a few seconds and then on again may resolve network issues without any additional troubleshooting. If you have phone service through your ISP, power cycling your modem may interrupt that service. You may need to contact your ISP in order to restore your phone service if your modem is reset or powered off. Ensure that you have alternative means to contact your ISP (such as a cell phone) to avoid unnecessary delays in restoring your Internet or phone service.

     

     

    1. If your computer has joined the correct Wi-Fi network but you are still unable to get online, you should check your TCP/IP settings in the Network pane of the System Preferences.
      1. Choose System Preferences from the Apple menu.
      2. Choose Network from the View menu.
      3. Select Wi-Fi, then click the Advanced button in the lower-left hand corner of the screen.
      4. Select the TCP/IP tab from the top of the screen.
      5. Your window should look like this (your IPv4 configuration may be different and your IPv4 address will definitely be different):

      6. If no IPv4 address appears, or if the IP address starts with "169.254.xxx.xxx", click "Renew DHCP Lease".
      7. Consult with your network administrator to determine the correct TCP/IP settings for your Wi-Fi network. Without the correct TCP/IP settings, your computer will not be able to get online.
      8. If your TCP/IP settings appear to be correct, and your computer still cannot access the Internet, check the DNS tab. See below for this tab. DNS is an Internet service that translates IP addresses into URLs and vice-versa. A correct DNS configuration allows your computer to connect to www.apple.com without having to enter the specific IP address of the Apple servers.

      9. You may want to contact your ISP for DNS addresses or use the DNS provided by a public service. To add a new DNS address, simply click the + button and enter the IP address for that DNS.
    2. Try connecting to your router through Ethernet, if your Mac has Ethernet. Connect an Ethernet cable directly to your Wi-Fi router from your computer.
    3. Check your range to the Wi-Fi router and reduce the effect of interference. If your computer is too far from your Wi-Fi router or your environment has too much Wi-Fi interference, then your computer may not detect the Wi-Fi network properly. The easiest way to check for range limits with your Wi-Fi network is to move your computer or your Wi-Fi router closer together and make sure that there are no obstructions (such as walls, cabinets, and so forth) between the router and your computer.

      See Potential sources of wireless interference for more information about interference, its causes and solutions.

    4. Try connecting to a different Wi-Fi network.

      If your computer does not exhibit any symptoms when connected to a different Wi-Fi network, then the issue may be related to your network router or ISP. In that case, you should contact the manufacturer of your router or your ISP.

     

    If Internet access is slow on your computer, confirm your network supports the correct Wi-Fi standards. 802.11n provides the fastest Wi-Fi speeds. Other standards are fast, but you should confirm that your computer is using the fastest protocol available.

    1. Hold the Option key while clicking the Wi-Fi menu.

      AirPort option key

      The PHY Mode line shows the protocol your computer is using to join the Wi-Fi network. If this does show the expected 802.11 protocol, you should check the settings of your Wi-Fi router. Consult the manufacturer of your router for information about configuring it.
