Hi there,
I'm Cherrelyn and I'm here to help.
Sounds like the update might have broken your network stack or driver settings. Since it’s affecting all connection types, it’s likely not hardware but something in Windows’ networking configuration. Please try fully resetting the network settings (including Winsock) and then reinstalling your network drivers from the manufacturer, not just Windows’ defaults. If that doesn’t work, booting into Safe Mode with Networking can help confirm if it’s a driver or software conflict.
I hope this will help and If you have any question please feel free to ask.
Warm regards,
Cherrelyn
