Fixing your Wifi manually

1. Check on your Apple's software.

We received some complaints that some Mac users encountered problems after updating their computers to a new version of Mac OS, especially the version of El Capitan after the update, some users found that their Mac was unable to connect to their wifi.

The software has been updated, but it wasn't that easy to fix as users also need to connect to wifi for an update, and the only option they have is mobile phone tethering.

Another factor is when you have a beta version OS running on your Mac, you might found your wifi dropping, only after the latest update it was fixed.

2. Check Apple's wifi recommendations.

If there was a problem while connecting to wifi, the Mac OS usually will give you recommendations to troubleshoot the problem if any is detected. You can access these recommendations simply by clicking on the wifi logo on your top right corner.

3. Check your broadband provider.

If all the steps above are not working, maybe the problem is on the provider's side, and with this, there is nothing much you can do about it. Some of the reasons we found are when the cabling to the house was at fault or bad weather/water harms the cables. To discover that all the problem is in this situation, you might want to check your ping first.

4. Restart your router/Mac.

To determine if your router is the problem, you should turn it off and turn it on again. You need to disconnect it from power for approximately 30 seconds to power your router, then plug it in and turn it back on.
