FIX: "You must log in to this network before you can access the Internet"

Every now and often when I open my laptop this always comes up and it annoys me all the time. "You must log in to this network before you can access the Internet" this happens when I connect to a wireless fidelity (wifi) connection or network to my laptop.

So I am now giving you a simple solution about this problem.

1. Open Firefox Mozilla

2. On the address bar type the following about:config

3. Click Accept the Risk and Continue

4. On the magnifying glass from the right type the following network.captive-portal-service.enabled

5. Below click the Toggle button from true to false.

6. Then close the Firefox Mozilla.

 I hope this will fix your problem.
