I try again, my P4's wifi is off (no signal) how do I turn on the wifi again? It has nothing to do with setup, I have control over the setup.

Happened to me as well yesterday with a white GHL logo on the PL4. The Wifi module simply turned off, although working perfectly before. I simply pulled the power plug of the PL4 and put it back in about a minute later and it is working again. Not sure what caused it, though.

I have turned off the power many times without wifi has restarted - i think the error is in the wifi and hope that GHL has a solution how to reboot the wifi

Have just (Saturday 27042019) made the update of wifi software to version 6961, this without the wifi restarting and info: The diodes on the P4 are both off

Then please check your wifi settings. On your screenshots the wifi-module seems to work, but it couldn't establish a connection. If there's no connection, both diodes are off.
The settings will be applied after disconnecting from the device.

The problem solved was a spelling error on the network name.
