Ethernet and WiFi stopped working

[j-me]

Laptop was working fine with Ethernet and WiFi. Disconnected to work on upstairs and now both will not connect to home network. Checked cables, red light blinks like trying to connect but no yellow throughput light. Have taken in and connected directly and still does not connect. 

Keep seeing message saying my firewall is turned off. Check firewall settings and says “there was an error opening windows defender firewall”  I cannot seem to do anything with windows defender firewall. Can’t restore defaults, cannot change notification, turn off/on nor see advanced security settings. 
hopefully, can get some help as this is very frustrating. 
thanks.

I changed out networks cables and but same result.
So I ran hp support assistant - network diagnostic. Result told me to contact hp support as there is a problem but cannot repair.

Appreciate the reply. This did not work for me. I was not prompted to reinstall the driver for WiFi. I had also opened a case with hp and they provided instructions to create a usb bootable install for windows 10. I have done that but got stuck on the drive partitioning step as win10 would not proceed and hp did not provide instructions for the non-happy path. I’ll call in tomorrow for assistance. 

thanks again.

I understand your concerns.

Please perform the wireless module test and check.

1. Power off the PC and make sure that it is completely powered off.

2. Press the power button and the moment you press the power button immediately start tapping F2 key, you should see the system diagnostics screen.

3. Look for the component test, under that all the hardware will be listed, please choose the wireless module test and initiate the quick test.

Note: If it fails it will generate a 24 digits alphanumeric failure id, please capture that.

Please let us know the result.

Have a nice day!!
