If your Mac says it is connected to WiFi but websites will not load, first check whether other devices still have internet. If a phone and TV work normally, focus on the Mac’s saved network, address, VPN, or DNS settings. If every device fails, use a router and provider check instead.
Start with a two-device check
Open two unrelated websites on the Mac, then try the same sites on a phone connected to the same WiFi. If only one website fails, the connection may be fine and that service may have a problem. If the phone also fails, check the gateway, modem, or provider. If the phone works, continue with the Mac steps below.
| What you see | Likely area | First test |
|---|---|---|
| Mac and every device cannot browse | Router, gateway, or provider | Check equipment lights and another connection |
| Mac fails but phone works on the same WiFi | Mac network profile or settings | Forget the network and join again |
| Mac works beside the router but not in its room | Coverage or band choice | Move closer and compare another band |
| Mac fails on home WiFi and a phone hotspot | Mac software or hardware | Update macOS and check WiFi diagnostics |
Turn WiFi off and reconnect
Click the WiFi control in the menu bar or open System Settings, turn WiFi off, wait a few seconds, and turn it back on. Restart the Mac if the connection still shows connected but no page can load. Apple lists restarting the Mac as an early step because it can renew the network address assigned when the Mac joins WiFi.
Forget the saved network
A saved profile can contain an old password or settings from a previous router. In System Settings, open WiFi, find the network details, and choose to forget or remove the network. Join it again and enter the current password. Menu labels differ slightly by macOS version, so use Apple’s current instructions if the wording on your Mac is different.
Do not factory-reset the router for a one-Mac problem. Resetting the router disconnects everyone and erases settings that may not be easy to restore.
Check the Mac’s address and DNS settings
Open the WiFi details for the current network and look at TCP/IP and DNS settings. Most home networks should use DHCP or automatic IP addressing and automatic DNS unless you intentionally configured a different setup. A manual address copied from another network can allow the Mac to join WiFi while preventing internet access.
If you recently installed a VPN, proxy, content filter, or security tool, turn it off for a short controlled test. Restore the setting afterward. Apple specifically includes VPN and security software in its troubleshooting path because these tools can block traffic even when the WiFi association remains active.
Renew the connection without changing everything
In the WiFi network details, look for the option to renew the DHCP lease. This asks the router for a fresh local address. It is less disruptive than deleting every network setting. After renewing, close and reopen the browser and test two unrelated sites.
If you use a work or school Mac, do not remove a management profile or security certificate. Ask the organization that manages the computer before changing those settings.
Compare another network
Connect the Mac to a phone hotspot or another trusted WiFi network. This test separates a Mac problem from a home-router problem.
- Works on the hotspot but not home WiFi: check the saved profile, router access controls, IP assignment, and WiFi security mode.
- Fails on the hotspot too: update macOS, check VPN or security software, and run Apple’s Wireless Diagnostics.
- Works only near the router: compare 2.4 GHz and 5 GHz, then improve placement or coverage.
Apple’s Wireless Diagnostics can collect information about the local wireless environment. It does not change the router by itself, so it is safer than copying an advanced channel setting from a random guide.
Check the router only after the Mac tests
If the Mac works on other networks but not at home, open the router app or administration page and check whether the device is paused, scheduled, or blocked by access control. A private WiFi address can make the Mac appear as a new client to a strict allowlist. Update the allowed-device entry rather than turning off the router firewall.
If several devices lose internet together, switch to our WiFi versus internet outage guide. If only one device has trouble, our one-device WiFi checklist covers the same decision boundary without assuming the router is broken.
When to contact Apple, your provider, or router support
Contact Apple or a repair provider when the Mac cannot see any WiFi network, WiFi is missing or disabled, or the Mac fails on every network after updates and diagnostics. Contact the internet provider when every device fails, the gateway shows a connection fault, or Ethernet and WiFi fail together. Contact router support when the Mac is the only blocked client and the router’s access rules do not explain it.
Bottom line
Separate a Mac-only problem from a home-wide outage, then forget and rejoin the network, check automatic IP and DNS settings, test without VPN software, and compare a hotspot. These steps preserve the rest of the household network while showing whether the fix belongs on the Mac or at the router.
