Have you experienced any Mac Problems Connecting to WiFi since installing MacOS Mojave 10.14 on a Mac? While MacOS Mojave works fine for most Mac users with compatible Macs (and even for many Macs that can not run under Mojave), a small number of MacOS Mojave users have found that networking without thread was a problem. Typically, Mojave's Wi-Fi problems are caused by a connection failure, frequent connection interruption, a reliable Wi-Fi connection, an inability to connect at all, or even General performance issues occurred only after you updated a Mac for MacOS Mojave.
Macs, like any computer, may lose their Wi-Fi connection. If you have reset your router, found that other devices are connecting to it, and your Mac still refuses to connect to the Internet, it is almost certain that the problem comes from the Mac itself.Although the problem is sometimes solved simply by giving a new start to the network, it often becomes too categorical to be solved. And when the problem seems to get mixed up, you do not know exactly what solutions can solve Wi-Fi problems on your MacBook Pro.
1. Check Your Mac’s WiFi Settings
The first thing to do when you experience WiFi problems is to check and validate your network settings in System Preferences to make sure everything is set up correctly.
- Open System Preferences and select the Network icon found in the Internet and Wireless section.
- Click the Advanced button at the bottom right to view more details about your network connection.
- In the TCP / IP tab, in most cases, you will need the Configure IPv4 option set to Use DHCP. The reason is that in OS X Lion, it was reported that manual configuration was a problem (although this only applies to versions prior to the first release of the operating system)
- You should also check the other tabs in the network, such as Wi-Fi, and check that the network you want to join is listed. Drag the networks in the desired order. For example, you can also move the network you want to connect to at the top of the list to make sure your Mac searches for it first.
2. Use Apple’s Wireless Diagnostics
macOS comes bundled with the Wireless Diagnostics Utility that allows you to detect common Wi-Fi issues. In addition, this application can also help you monitor wireless connections in case of intermittent connectivity failure. It also warns you when a connectivity failure is detected.
- Open Wireless Diagnostics on your Mac. You can take Spotlight help to open it quickly.
- Now, click on the Windows menu and select Performance.
Then you should see three graphs showing transmission rate, signal quality, and signal and noise levels.
3. Remove and Re-Add The WiFi Service
One thing to try when you are having wireless network problems is to remove and then add the WiFi service.Follow the steps below:
- Open the network settings under System Preferences.
- In the left pane, select the Wi-Fi icon, then click the Delete button (the small "-" icon) and confirm it when prompted.
- Once the WiFi service is removed, add a new one using the Add ("+") button, and enter the name of the new connection followed by Create. This establishes a new WiFi connection with the default settings.
- Just browse the different tabs to make sure the WiFi is set up correctly (things like the password) and try reconnecting to your wireless access point. If prompted, re-enter the information that may have been lost when you removed the service.
4. Check your software compatibility
First, try a few easy steps. Some users have reported that the problem of Wi-Fi appeared after upgrading their Mac. This particular problem has been largely met with the Mac OS El Capitan version - once the update process was completed, problems connecting to wireless networks appeared. Apple released a software update to fix the problem, but owners of MacBook Air still reported issues, because for many, a Wi-Fi network was the only connection available to the Internet. IFolks users have found an option to access the update: share the connection from their mobile phone. If this option is offered to you, it is worth trying, but keep in mind that cellular data restrictions will have a maximum of GB available. In addition, Wi-Fi issues are sometimes encountered when computers run a beta version of MacOS. For example, issues related to frequent dropouts of Wi-Fi when running High Sierra beta (but resolved in update 10.13.12).
- Restart your Mac in safe mode.
- Restart again (this will delete the cache).
- Restart the WiFi router to which your Mac is connected.
- Make sure you are using the latest firmware of the Wi-Fi router.
- Connect to the 2.4 GHz network if you are on a 5 GHz G network or a B network.
- Reset the Mac SMC.
