connected to wifi no internet 10.15.4

macbook pro 13inch 2019

just updated to 10.15.4 and no problems for a day then everything stopped working on internet.

Troubleshooting:

• connected to 3 different routers

• connected to iPhone personal hotspot

• restarted and shutdown multiple times

• restarted in Safe Mode

launched WiFi Wireless Diagnostic tool and changed DNS as suggested but nothing as well. no other problems resulted from the Tool except minor things.

I have no idea what else I can do. I unfortunately don’t have an Ethernet adapter to see if that works.

help.... pleaaaaase
