No need to worry, as there are many simple ways and solutions as to how you will be able to fix your Macbook’s wifi connectivity.

1.Turn your wifi settings on and off:

This is pretty simple. Restarting your Mcbook’s wifi settings may be the root cause of your problem, so when you suspect your wifi isn’t connecting properly, try switching it on and off a few times, as well as your wifi router.

2. Restart your Macbook:

Sometimes, your laptop may just need a rest and to reboot. When your wifi isn’t working, the first thing to do is to try restarting your Macbook to see if that fixes it.

3. Check your router:

It may also be the wifi’s problem. Check your router to see if it is properly connected. Check its cables to see if it is properly connected, that you still have data from your network to use the internet, and if your wifi router’s firmware is updated. You can go to your wifi’s network settings through your Macbook by typing the IP address on your browser, which is “192.168.1.1”.

If internet connection is working fine with other devices and nothing is the matter with your wifi router, then it’s time to delve into the Macbook’s wifi settings.

4. Create a custom DNS:
