What do I do when my computer keeps telling me Windows Firewall is off, but it won’t let me turn it on. When I try to turn it on, there is this message that says “Windows Firewall is using settings that may make your device unsafe.” I can’t connect to the internet either.

Thank you for visiting UgetFix. We haven't been reported about this Firewall problem before, so we've initiated an analysis about it. It turns out that many people encountered this problem, bu did not receive a proper help from Microsoft.
Actually, it seems that the exact reason of the problem is not clear, but could you please try to recall if you have recently initiated some important system's changes? It might be that you have installed malware or some aggressive PUPs that are currently interfering with Windows Firewall. In this case, we would strongly recommend you to check the system with a reputable anti-malware, lets say Reimage. The mentioned program works as a PC optimizer as well, so it will check your PC for problematic system files, registries or software.
If removal of PUPs or incompatible software did not help, you may try to perform the following registry tweak:
1. Press Windows key + R, type "regedit" (without qoutes), and press Enter.
2. Navigate to the HKEY_LOCAL_MACHINESYSTEM/CurrentControl/Setservices/BFE.
3. Right-click on the BFE and select Permissions.
4. Now click ADD and type "Everyone" (without qoutes).
5. Click OK and click on "Everyone" entry.
6. Mark "Full Control" over Permissions for Everyone.
7. Finally, close Registry Editor and restart your PC.
Once you try this command, let us know if it helped to fix “Windows Firewall is using settings that may make your device unsafe" error.
