Hello, the recommendation when this happen as the first step will be to make sure that the switch that turns on and off the Wi-Fi adapter in your laptop is on, it is a common mistake to turn off this switch and receive this error.
If that is not the case, it is possible that the wireless card stop working, if that is the case the recommendation will be to contact the OEM manufacturer of your system and see if they can replace the adapter or perform a test to make sure that the adapter is working properly.
Hi Ernest, if your wireless adapter was able to connect to the router and browse the net, the error you're getting from wifi tech might just be a software problem, have you tried reinstalling the wifi tech?
you may download the generic version of the software from the link below (do take note the generic version might not be tested on your laptop, it's best to you the version that comes with your laptop)
hope this help
