Pc connected but it picks up no signal

hello everyone, I have this problem where my pc is connected to the internet (says ‘Connected, secured) and everything but it completly stops picking up signal and nothing works as if it wasn’t. this thing ONLY happens on my pc, and only happens for about a day, then I go to sleep and the day after it works again like nothing just for it to repeat a few times a month. I tried a lot of things but nothing worked and i’m exhausted this literally don’t make sense, any solutions??
