I am typing from my phone due to the nature of the issue.
This morning, I woke up to find that my computer had automatically installed the latest quality update, KB5007186. I thought little of it, and opened up Brave, the browser I use. I discovered that I could not connect to any websites despite having full internet connection, except one whose url has apparently been banned or restricted here since it won't let me complete it...? Anyway, every website gave me the same error: ERR_CONNECTION_RESET. I don't know how to workaround this. I have done everything the internet suggests. I have uninstalled all network drivers. I have used a different network adaptor, cycled the router and modem several times, rebooted, restarted, ran PC Matic, rebooted again, and still to no avail. I've now been waiting for an hour for the update to be uninstalled in Safe Mode. I am nearly certain that the issue is with this update, since I had ZERO issues with connectivity beforehand.
I need the internet especially much since I am trying to find a job and I like to respond as soon as possible to emails. And it sucks that I can’t do literally anything that requires the internet.
The same thing happened to me. I have an error stating that my wifi network adaptor, which is intel dual band wireless-AC 8260, is not functioning. However, when I go to device manager, it states the driver is fine and there were no other updates to be installed for it. I uninstalled the update and now it is working as well.
