My wifi wont turn on. When I ask it to turn on it just reverts to off. My Mac does use the network with the ethernet cable. But I cannot use the wifi.

Hello, argo1200.
Sorry that you're having this trouble with your Mac.
Try using the wi-fi connection only. Disconnect the ethernet cable from the router. You probably don't need to use both connections.
Reboot your Mac and see if the problem is cleared. If rebooting your Mac doesn’t fix things, see if the problem still happens in Safe mode (hold the shift key down at startup). It can take much longer to safe boot (10 min) so be patient.
How to use safe mode on your Mac - Apple Support
Safe mode forces the OS to clear certain caches and logs and do other miscellaneous housekeeping. It's non-destructive to user data so is safe to do. Very often certain weird software behavior is corrected by simply logging in this way as a troubleshooting method. When you're in safe boot, the machine will not be at its best performance, especially with graphics, but that's expected.
Does the problem persist while in Safe mode?
Exit safe mode by restarting your Mac normally and re-evaluate the issue again.
If the problem is still unresolved, please return here and post a reply and we’ll see what else we can come up with for help.
