My wifi had been acting weird on my pc, I was casually using my pc and got a ping spike for a few hours until I turned it off and on to come back to it not working at all but on other devices it is fine.
On my pc it specifically says “No internet, secured”. I have tried a different wifi usb stick and didn’t it didn’t solve anything and just had the same thing. I don’t know much about it, my pc is about 5 years old so I don’t know if its just getting old. I have also tried different usb ports.
