Mac might be a beast in the computing world, but it isn’t immune to Wi-Fi issues and disconnections. If a spotty wireless connection is giving you sleepless nights, this guide here is what you need. Keep reading to know how you can fix dropped connections and Wi-Fi problems on your own. Surely, if these don’t work, you have to head to the Apple service center.
Diagnose the Problem
It is an obvious solution, but one that a lot of Mac users ignore or forget. If you want to fix the issue, you need to find out why your Wi-Fi is giving an issue. Use the in-built Wireless Diagnostics tool to identify the root cause of the problem. Open the Wireless Diagnostic tool by holding the Option key or through Spotlight and open the Wi-Fi settings found within the Control Center.
After the tool has finished analyzing your system, it will provide you with a few reports and insights. One of the most important reports to browse is the Performance report, where you can see your wireless network’s signal quality, transmission rate, and noise level.
The signal quality can be improved by placing your Mac closer to the router. If the noise levels are spiking, you need to change from the 2.4Ghz band to the 5Ghz band.
Extend the Wi-fi Network to Boost Signal Quality
If the primary problem is the signal quality, it can be improved by extending the Wi-Fi network. Wi-Fi connections are usually unreliable in large spaces, especially in specific corners of the house or office. You need to get Wi-Fi extenders for Mac and amplify the signal quality. The extenders will help improve the Internet connection in those parts of the house that were previously experiencing dropped connections or other connectivity issues.
Restart Your Mac and/or Router
Restarting your Mac is the most uncomplicated and effective way to resolve Wi-Fi issues. If your system readily connects to the Wi-Fi network after restarting, the problem was temporary, and it has been solved.
But if restarting your Mac didn’t solve the issue, you can switch off and on the router. When you reboot the router, it cleans the short-term memory of the device and helps the router function much more smoothly. Also, you can reselect the least crowded channel.
DNS (Domain Name Server) Reconfiguration
The DNS is responsible for converting IP addresses to comprehensible web addresses. It is similar to a phone book, but for the Internet. Reconfiguring the DNS can help solve the issue of your Mac refusing to connect to the Wi-Fi network.
At times, the specific DNS for a service provider might not function properly. The theory can be tested with a public DNS, like Namecheap and Google.
You can add a free public DNS by going to the Network Screen, clicking the Advanced button, and choosing the DNS tab. You can select the + button to add a new DNS and then enter the IP address. Then, click OK and monitor the connection. If it works fine, the problem is with the DNS, and it must be reconfigured. You can talk to your ISP for guidance.
Reset the PRAM/NVRAM and the SMC
Suppose your Wi-Fi connection keeps dropping or disconnecting. In that case, you can consider resetting the PRAM (Parameter Random Access Memory)/NVRAM (Non-volatile Random Access Memory) and the SMC (System Management Controller). These are the key areas that control the fundamental operations of your Mac. However, you cannot reset the SMC on Apple silicon machines because they don’t have the feature. The equivalent is to switch off your machine, wait for thirty seconds and start the machine.
For Intel machines, there are a few steps that users need to follow when resetting PRAM.
- Shut down your Mac and wait until the fans stop functioning and the screen goes dark. Then, switch on your system again.
- When you see Mac’s startup routine, press Command + Option + P + R. Keep holding these keys until the start sound is heard and the Apple logo is seen on the screen.
- Then, release the keys, and NVRAM/PRAM is reset.
If your Mac comes with SMC, the process depends on whether you have a removable or non-removable battery.
If the battery is removable, you have to switch off your system and unplug the cord. You need to remove the battery and then press the power button. Keep holding the button for five seconds and then release it. After that, put the battery back in and reattached the plug. Then, switch on your Mac.
If you try everything on this list and your Wi-Fi is still acting funny, call the professionals at the service center.
