Wi-Fi Connectivity on Your Portable Mac Computer
If you are experiencing problems with Wi-Fi connectivity on your portable Mac, you should first determine what the issue is. Knowing what’s wrong will help you identify appropriate troubleshooting steps.
To determine the issue, try to answer the following questions:
Does the symptom occur with more than one Wi-Fi device? Wi-Fi issues may be related to the network in question. Usually, if your iPhone, Apple TV or any other devices are able to get on the Internet, then the issue is probably with your computer.
If you only have one Wi-Fi device and no other device using Wi-Fi is available, proceed as follows:
- Make sure your software is up-to-date and install all software updates available for your Mac. In case of a third-party Wi-Fi router, check with the manufacturer to confirm that it has the latest firmware installed. Follow the manufacturer’s instructions for updating the firmware.
- Check your connections. Disconnected or loose cables can cause networking issues. So, you should verify that all Ethernet and power cables connected between your Wi-Fi router and your modem are correct. First, check to see if your router and modem are on, then disconnect and reconnect your Ethernet cable. If your Ethernet m\cable is damaged, replace it. This may resolve the issue without any further troubleshooting.
- Verify that you are using the recommended settings for your device.
- Restart your network devices. Powering your modem or router off for a few seconds and then on again may resolve network issues.
Keep in mind that 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 while your modem is powered off. You will want to ensure that you have an alternate means to contact your ISP, such as a cell phone, to avoid delays in restoring your Internet or phone service.
