Mac Will Not Connect to Wi-Fi? How to Fix It at Home or at Work
Mac will not connect to Wi-Fi at work or home? Check where the problem is, restart, forget the network, renew your IP address and check work network settings.
If your Mac will not join the Wi-Fi or keeps dropping, work through these checks in order. Most take a minute. The first few tell you whether the problem is your Mac, the network or your internet service. At work, remember that the network may be managed by someone else.
1. Work out where the problem is
Check whether other devices can join the same network. If they cannot, the problem is the network or the internet service, not your Mac. On your Mac, open System Settings and click Network. The service you are using should show a green indicator and the word Connected. If you are connected to Wi-Fi but cannot reach the internet, the network’s own connection may be the problem.
2. Use the built-in checks
Click the Wi-Fi icon in the menu bar and choose Wi-Fi Recommendations. If your Mac detects Wi-Fi issues, it shows them with suggested fixes. Wi-Fi Recommendations is not available for enterprise networks or Personal Hotspots.
If you can join the router but pages will not load, run Wireless Diagnostics. Hold the Option key, click the Wi-Fi icon and choose Open Wireless Diagnostics. It analyses the connection and lists problems and best practices. It does not change your network settings. It also saves a file in the /var/tmp folder that your network administrator or IT support may find useful.
3. Restart the equipment
Check that your modem, router and any hubs are plugged in, turned on and fully started, then try resetting them by unplugging them for a couple of minutes and plugging them back in. Then restart your Mac.
4. Forget the network and join again
Open System Settings and click Wi-Fi. Click Details next to the network you are connected to, then click Forget This Network. Join the network again and enter the password.
If you use iCloud Keychain with the same Apple Account, forgetting a network on one device makes your other devices forget it too, so have the Wi-Fi password handy. If your Mac is managed by an organisation, you may not be able to forget the network.
5. Renew your IP address
Open System Settings and click Network, Wi-Fi, Details, then TCP/IP. Click Renew DHCP Lease, then OK. This refreshes the Mac’s connection details and can fix some connection problems.
6. Work or school networks
Many business networks use a security standard called 802.1X. Your network administrator usually sends you a configuration profile with the settings you need. Install it, then open System Settings, click Network, click Wi-Fi, click Details, click 802.1X, choose the profile and click Connect.
If a work or school Wi-Fi network keeps asking for a password, stop changing advanced settings and contact the network administrator. They may need to update the network setup on your Mac.
7. Private Wi-Fi addresses
To protect your privacy, your Mac uses a different Wi-Fi address on each network. This does not affect most networks. If your Mac cannot join a network, or cannot reach resources after joining, install the latest software updates and try again before you decide whether to turn it off. Businesses may need to update their network security to work with private addresses, or use a management profile to turn the feature off for their devices.
If you need to change it, open System Settings, click Wi-Fi, click Details next to the network and choose Off, Fixed or Rotating next to Private Wi-Fi Address. This needs macOS Sequoia 15 or later. Ask before changing Private Wi-Fi Address on a managed network.
8. Wi-Fi 6E and Wi-Fi 7 networks
If your network uses the 6 GHz band and you have problems, you can turn off Wi-Fi 6E mode for that one network. Open System Settings, click Wi-Fi, click Details next to the network and choose Off next to Wi-Fi 6E mode. This does not affect other networks.
9. Interference and distance
Common causes of poor Wi-Fi include distance from the router and interference from power cables, microwave ovens, fluorescent lights, wireless video cameras and cordless phones. Concrete, plaster and especially metal can weaken the signal. Move closer to the router and see whether things improve. If you have a weak spot in one part of your home or office, see our guide to Wi-Fi extenders, mesh systems and router position.
10. VPN and security software
If you use a VPN or security software, turn it off briefly and see whether the connection returns. If it does, the software needs to be set up differently. Ask us to take a look.
When the network is the problem
If several people are affected, or the problem happens in the same area every time, the cause may be an access point fault, a crowded network or a configuration problem. That needs the network checked, not your Mac. See our Networks, NAS, Wi-Fi & Printers service for businesses or our Wi-Fi & Home Networks service for homes, or contact Your Mac Tech.
