How to troubleshoot Wi-Fi connectivity issue on your Mac

In this high tech world, internet connectivity is an essential part of everyone’s life.  If  internet applications such as Mail, iChat or App store are not connecting to their server, web pages are not opening on Safari browser or other web browser and showing blank pages or an alert that “You are not connected to the Internet” on your Mac, there can be many reasons of losing internet connection. If you are using Wi-Fi Router and unable to figure out the network issue on your Mac, here we will help you with some troubleshooting steps to get your Internet connectivity issue fixed.

1. Make sure that your Wi-Fi is enabled.

Sometimes, the Wi-Fi card may be disabled accidentally and turn off the internet connectivity on your Mac. Moreover, if Wi-Fi signals are not there in Wi-Fi menu, it means your Mac is not connected to a Wi-Fi network. In such a case select “Turn on Wi-Fi ” from the menu on the top right corner of the screen.

If the Wi-Fi icon does not appear in the menu, click on the Apple Menu and select “System Preferences” from the drop down menu. Click on the Network icon a, select Wi-Fi and then check the box in front of “Show Wi-Fi status in menu bar.”

If you see that your Mac is already connected to Wi-Fi, proceed to next step.

2. Make sure that your Mac is connected to correct Wi-Fi network.

If your Mac is still not connected to Internet, check the list of Wi-Fi networks available on your Mac and make sure that it is associated to correct network. If it is not, then select your network and enter your password to get connected.

Moreover, if your network is not listed in Menu, you may join the Wi-Fi network, by selecting “Other Network” from the Wi-Fi menu; doing so will prompt you to configure the network name and security setting.

3. Check TCP/IP settings on your Mac.

After connecting your computer to the correct Wi-Fi network, if you are still unable to get online, you should check TCP/IP settings in the network pane by following the below given steps:

• On your Mac, select “System Preferences”from the Apple
• Select “Network” from the “View”
• Now, choose “Wi-Fi” and then click on the “Advanced” button in the bottom-left corner of the screen.
• On the top of the screen, select the “TCP/IP” tab.

• If there is no IPv4 address or if the IP address initiates with “169.254.xxx.xxx”, click “Renew DHCP Lease“.
• Contact your network administrator to get and configure the correct TCP/IP settings for your Wi-Fi network.
• If your TCP/IP settings are showing correct but your Mac still does not have internet access the Internet, check the DNS tab. Here, you may see DNS servers address, if you are not sure it is correct, 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 type the IP address for that DNS.

4. Try connecting to your router through Ethernet.

If your Mac is still not connected to internet, you may connect an Ethernet cable directly to your Wi-Fi router from your computer and access internet on your Mac.

5. Check the range between your Mac and router.

If you system is located far from your router, reduce the effect of interference and range limit by moving your computer or your Wi-Fi router closer together. Also make sure there are no barriers (like wall, cabinets etc.) between your Mac and router.

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