# MacBook Wi-Fi Keeps Disconnecting — How to Fix It
If your MacBook keeps dropping its Wi-Fi connection every few minutes, you're not alone. This frustration affects plenty of Mac users, and the good news is that the cause is usually something you can either fix yourself or get sorted quickly. The problem might be as simple as a software setting, or it could point to a hardware issue with your Wi-Fi card. Either way, we'll walk you through what to try first before you need professional help.
Check Your Wi-Fi Router First
Before blaming your MacBook, spend a moment on your router. Restart it by unplugging the power cable for 30 seconds, then plug it back in and wait for it to fully restart. This fixes the majority of temporary connection dropouts.
While you're at it, check whether other devices in your home are also losing connection. If your phone, tablet, or another laptop can't stay connected either, the problem is almost certainly your router or internet provider, not your Mac. In that case, contact your ISP or consider whether your router is old enough to need replacing.
If only your MacBook is having trouble, you're looking at a MacBook-specific issue. Move on to the next steps.
Forget and Reconnect to Your Network
Sometimes macOS holds onto outdated or corrupted network information, which causes it to drop the connection repeatedly. The fix is simple: forget the network and reconnect to it fresh.
Go to System Settings, then Network, and select Wi-Fi. Click on your network name and choose "Forget This Network". Once you've done that, select the same network again from the available networks list and re-enter your password. This clears out any corrupted settings and often solves connection dropouts immediately.
Give it a few hours of normal use before deciding whether this worked. Occasionally the problem takes a little time to reveal itself again.
Update macOS and Restart Your Mac
Software updates from Apple often include Wi-Fi stability improvements, so check whether your MacBook is fully up to date. Go to System Settings, select General, then Software Update. Install any available updates and restart your Mac afterwards.
Even if there are no updates available, a simple restart of your Mac can solve stubborn Wi-Fi dropouts. Shut down completely, wait 10 seconds, then power back on. This clears your Mac's memory and resets network connections, which is surprisingly effective.
Disable Wi-Fi Interference and Power Saving
Your Mac has a few power-saving settings that can interfere with Wi-Fi stability. In System Settings under Network, click Wi-Fi Settings, then Advanced. Look for any options related to low power mode or Wi-Fi power saving, and make sure these are disabled.
Also check whether you have Bluetooth devices nearby. Although Bluetooth and Wi-Fi operate on different frequencies, they can sometimes interfere with each other, particularly if you have multiple devices connected at once. Try disabling Bluetooth temporarily to see whether your Wi-Fi becomes more stable.
When It's Your Wi-Fi Card
If you've worked through all the software fixes above and your MacBook still keeps disconnecting, the issue is likely a failing **Wi-Fi card**. This is a small piece of hardware inside your Mac that handles wireless connections, and unfortunately it can wear out or fail, particularly in older MacBooks.
Signs of a failing Wi-Fi card include connection dropouts that happen regardless of which network you're on, weak signal strength even when you're close to the router, and problems that started suddenly without any recent software changes. If you're seeing these patterns, you need professional help to replace the card.
MacBook Wi-Fi cards cost between R1,500 and R3,500 depending on your model, plus labour. It's not something to attempt yourself unless you're experienced with MacBook repairs, as the hardware sits deep inside your machine.
