Hi Anwille,
Thank you for your help. I have done the following with no success.
- updated wifi driver
- re-install wifi driver and restart pc
- RAN DISM and SFC... no integrity violations
- uninstalled most recent windows update and restarted machine
- tried to restore to a previous restore point but it encountered an error (0x80042318) which prevented it from restoring. Said it was a volume shadow copy service error.
Please advise what the next steps should be.
