Troubleshooting Mac Connecting to Wi-Fi But No Internet

Hey there, Readers!

Are you facing the frustrating issue of your Mac connecting to Wi-Fi but having no internet access? Fear not! In this comprehensive guide, we’ll dive into the potential causes and provide step-by-step solutions to get your Mac back online.

Network Connectivity Issues

Misconfigured Router Settings

Inspect your router’s settings to ensure it’s set up correctly. Check for any incorrect configurations or outdated firmware that could hinder internet connectivity. Restarting the router can also resolve temporary glitches.

DNS Cache Corruption

Corrupted DNS cache entries can interfere with your Mac’s ability to resolve domain names to IP addresses. To fix this, flush your DNS cache by entering the following commands in Terminal:

sudo dscacheutil -flushcache
sudo killall -HUP mDNSResponder

Faulty Wireless Adapter

In rare cases, a faulty wireless adapter can be the culprit. To check, connect your Mac to an Ethernet cable and see if you gain internet access. If so, the issue lies with your Wi-Fi adapter, which may need to be replaced.

Disabled Wi-Fi Services

Ensure that the necessary Wi-Fi services are enabled on your Mac. Navigate to System Preferences > Network and check if “Wi-Fi” is listed in the left-hand menu. If not, click the “+” button and add it, selecting your Wi-Fi network from the list.

Other Potential Causes

Firewall Interference

Disable your firewall temporarily to rule out any interference. If you regain internet access, re-enable the firewall and adjust the settings to allow connections from your Mac.

Proxy Server Misconfiguration

If you’re using a proxy server, it may be misconfigured. Disable it in System Preferences > Network > Advanced > Proxies and see if that resolves the issue.

Troubleshooting Table

Problem Solution
Router misconfigured Check router settings, restart router, update firmware
DNS cache corrupted Flush DNS cache using Terminal commands
Faulty wireless adapter Connect via Ethernet, replace adapter if needed
Wi-Fi services disabled Add “Wi-Fi” in System Preferences > Network
