Macbook Air WiFi Connection Timeout problem
I have a Macbook Air 13" Early 2014 with macOS High Sierra 10.13.
The problem I have is that my Internet connection (Wi-Fi) keeps going off every 5 minutes or less. When I start my Mac, Wi-Fi works perfectly, but after a few minutes, the Internet connection goes off. If I disconnect Wi-Fi and reconnect after a few seconds, the Internet connection works, but only for a few minutes, and then I have to disconnect and connect again.
When I connect the mac with others wifi works perfectly but the one at home gives me this problem only on my macbook. Because i have also an iphone and ipad and for them (the wifi that i use at home) works perfectly.
It's very annoying. I had the same issues with macOS Sierra, so I decided to update the OS, but it's the same.
If someone can help me I'll be really grateful, thanks.
Troubleshooting can be a process of elimination and often requires patience. Below are a few things you can try.
Try another 'Wi-Fi' network
It'd be interesting to see whether your MBA can maintain an internet connection from another Wi-Fi network. If you have an iPhone you can share an internet connection from its cellular connection and connect to that via your Mac's Wi-Fi port? Does this allow your MBA to browse the web, send/receive emails, etc and maintain the connection for longer than the five or so minutes you're having problems with?
Another way to test this is via a public Wi-Fi services (McDonalds, Starbucks, etc).
Test your Wi-Fi network
If your MBA connects fine to other Wi-Fi networks, then it's time to test your home Wi-Fi connection with other devices (such as an iPhone, iPad, etc) to see if they also drop a connection. If they do then you know it's your Wi-Fi network that needs investigating.
On the other hand, if they connect fine, it may be time to reboot your Wi-Fi router. This is because your router may have a limit on how many devices can be connected at any one time, or may struggle when too many devices are connected.
To do this, switch the router off for about a minute and then switch it back on. Wait a couple of minutes and then try connecting your MBA and testing to see what happens.
Remove and then add back your Wi-Fi service
I would totally remove your Wi-Fi service, restart, and add your Wi-Fi service back.
To do this:
- Go to Apple > System Preferences > Network
- Select the Wi-Fi service on the left-hand side
- Click on the cog icon at bottom-left and select Make Service Inactive
- Now delete the service by clicking on the minus sign (i.e. the - button) at left of the cog
- Click on the Apply button
- Exit Network preferences
- Restart your MBA
- Go to Apple > System Preferences > Network
- Click on the plus sign (i.e. the + button) at left of the cog
- In the pop-up window, ensure that Wi-Fi is selected from the drop-down menu
- Click on the Create button
- Make sure Wi-Fi is on and connected (it should remember your previous settings, but if not just re-add your Wi-Fi network again)
Run Wireless Diagnostics
You can use Wireless Diagnostics to analyse your Wi-Fi network. Follow these steps:
- Close any apps you have running
- Connect to the Wi-Fi network
- Hold down the option key and go to the Wi-Fi status menu and select Open Wireless Diagnostics
- Enter your administrator name and password
Now follow the steps to see whether any problems are found.
