When your MacBook is connected to a network but can't access the internet, it typically indicates an issue with your network settings or a problem with your internet service provider (ISP). Here are the most common causes:
DNS Issues: The Domain Name System (DNS) translates domain names into IP addresses. If your DNS is misconfigured, it can prevent you from accessing websites.
IP Address Conflicts: Two devices on the same network may be assigned the same IP address, causing conflicts that disrupt internet access.
Wi-Fi Configuration Errors: Incorrect Wi-Fi settings or saved credentials may cause connectivity issues.
Router Issues: Sometimes, the router itself may be experiencing problems that affect the internet connection, even though Wi-Fi is functioning.
ISP Problems: Your Internet Service Provider could be experiencing temporary outages or maintenance.
The simplest solution is often the most effective. Restarting both your MacBook and router can resolve many network-related issues. This process clears temporary settings and resets the network configuration.
Steps:
Shut down your MacBook and restart it.
Turn off your router, wait 10-15 seconds, and then turn it back on.
Insight: Restarting the router can help resolve issues such as IP conflicts and temporary service interruptions from your ISP.
Ensure that you’re connected to the correct network and that the network is functioning properly.
Steps:
Click on the Wi-Fi icon in the menu bar at the top of your screen.
Make sure you are connected to the correct network and not a different or guest network.
Try disconnecting and reconnecting to the Wi-Fi network.
Example error message:
“Connected, No Internet Access” – indicates that your MacBook is connected to the network, but not receiving internet service.

Sometimes, stored Wi-Fi settings can cause connection issues. Forgetting and reconnecting to your Wi-Fi network can help reset the connection.
Steps:
Open System Preferences > Network.
Select Wi-Fi from the left sidebar.
Click Advanced.
Find your Wi-Fi network, select it, and click the minus (-) button to remove it.
Reconnect to the network by selecting it from the list of available Wi-Fi networks.
Insight: This action clears cached Wi-Fi information, allowing your MacBook to establish a fresh connection.
If your MacBook is not getting an IP address from your router, renewing the DHCP lease can resolve the issue.
Steps:
Go to System Preferences > Network.
Select Wi-Fi and click Advanced.
In the TCP/IP tab, click Renew DHCP Lease.
Restart your MacBook.
Example error code:
"IP address conflict" – this could appear when there’s a duplicate IP address in the network.
Screenshot suggestion:
Show the Renew DHCP Lease option in the TCP/IP settings.
A misconfigured DNS can lead to internet access issues. Switching to a reliable DNS service like Google's Public DNS or Cloudflare’s DNS can resolve these issues.
Steps:
Open System Preferences > Network.
Select Wi-Fi, then click Advanced.
Go to the DNS tab and remove any existing DNS entries.
Add Google's DNS servers:
8.8.8.8
8.8.4.4
Alternatively, add Cloudflare's DNS servers:
1.1.1.1
1.0.0.1
Click OK and restart your MacBook.
Insight: DNS changes often resolve issues like "site not found" errors when browsing.
If the above steps didn’t resolve the issue, resetting your MacBook's network settings can help clear all configurations and restore default settings.
Steps:
Open System Preferences > Network.
Select Wi-Fi, then click the minus (-) button to remove it.
Restart your MacBook.
Go back to System Preferences > Network and click the plus (+) button to re-add Wi-Fi.
Reconnect to your Wi-Fi network.
Insight: This step resets network configurations, which can fix persistent issues caused by misconfigurations.
If your MacBook is still not connecting to the internet, the problem might lie with the router. Check the following:
Ensure that the router is powered on and connected to the internet.
Try restarting the router or checking the router’s status page for any issues.
If multiple devices are connected to the network but none have internet access, the issue is likely with the router.
Insight: Some routers have settings that limit internet access based on devices, time of day, or network traffic. Resetting the router can clear such configurations.
This issue is typically caused by incorrect network settings, DNS issues, or problems with the router or ISP. Follow the troubleshooting steps outlined in this guide to resolve it.
Check if other devices connected to the same Wi-Fi network can access the internet. If they can, the issue is likely with your MacBook. If they can't, the issue is probably with your router or ISP.
Yes, using a VPN can sometimes prevent access to the internet. Disconnect from the VPN and check if the issue is resolved. If it is, contact your VPN provider for further assistance.
If multiple devices on the network are affected, the issue may be with your ISP. Contact your ISP to check for outages or issues in your area.
"Connected to Network but No Internet Access" is a common issue that can be resolved by following the troubleshooting steps outlined in this guide. Whether the problem lies with your MacBook, router, or ISP, there are a variety of solutions available, from renewing DHCP leases to changing DNS settings and even resetting your network configuration. With a little patience and persistence, you’ll be back online in no time.
If you continue to experience problems after following these steps, don't hesitate to contact your ISP or Apple Support for additional assistance.
