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:
Run Wireless Diagnostics
You can use Wireless Diagnostics to analyse your Wi-Fi network. Follow these steps:
Now follow the steps to see whether any problems are found.
