We all rely on Wi-Fi to access the internet from anywhere, especially when we use our MacBook. That’s why it’s imperative to have a fully functioning Wi-Fi connection. However, there are times when we can encounter Wi-Fi problems and glitches. Even if these are not always common, they are prevalent and we must find a way to deal with them.
What causes Wi-Fi problems?
These issues can appear due to a variety of things. Either the Wi-Fi connection is not started, the connection is very bad or unstable, or you don’t have access to the network in question. Regardless of the situation, there’s always a fix.
Run some Wireless Diagnostics
Click on the Wi-Fi icon in the top right, and then open the Wireless Diagnostics. Here your Mac will assess the situation and then it will provide you with potential fixes. Granted, it won’t always fix the problem, but it’s definitely the right starting point.
Reset the Wi-Fi settings
Shut down all the browsers, go to the Apple menu and here you want to choose Go/Go To Folder. Paste this “/Library/Preferences/SystemConfiguration/” and then here you want to select the files:
- NetworkInterfaces.plist,
- com.apple.airport.preferences.plist,
- com.apple.network.eapolclient.configuration.plist,
- com.apple.wifi.message-tracer.plist,
- preferences.plist.
Move these files to a new folder on the Desktop, and now you can start your Mac. That will automatically restart the Wi-Fi settings and most likely fix your issues.
Change the Wi-Fi sleep mode Settings
Sleep mode settings can sometimes lead to Wi-Fi issues. What you can do is to enter System Settings/Battery/Options and here for the Wake option, choose Never.
Flushing the DNS cache
It’s also possible that the Wi-Fi issue is caused by a DNS cache problem. A Mac cleanup tool has in-built features that can help flush the DNS cache without any hassle. That’s a great way to ensure that your Mac runs flawlessly, and it will make it easier to prevent problems down the line.
Reboot the router
There are times when the Wi-Fi problem doesn’t stem from your Mac. It might be caused by the router. In that case, the best approach is to just restart the router and see how it all works. It’s one of the better solutions to consider, and it certainly works without any hitch.
See if your security software or VPN made any changes
You can find security software or VPN solutions that will try to replace or switch off your Wi-Fi. That’s why you want to ensure those tools are turned off, or you added exceptions in place. Go through their settings and make the necessary adjustments!
It’s always a great idea to check the current Wi-Fi settings and see if anything is going wrong. The best approach is to always focus on implementing one solution at a time, and you should start with the in-built diagnostics. If those don’t offer a meaningful solution, then you can try to reset the Wi-Fi, reconnect to the router, or even restart the router. Doing these one step at a time will minimize risks, while also making it easier to narrow down the right fix!
