Most likely a problem with the signal being received by the PC, make sure that there aren’t any other devices that can interfere with the WiFi signal, such as Bluetooth adapters, or USB-C hubs.
I have had problems with interference with USB Bluetooth adapters in the past, also USB-C hubs with poor shielding can be problematic. If you are using 2.4 GHz wifi on your PC, it might be worth switching it to 5 GHz if your PC and router support it.
Also try moving your PC closer to the router, if this helps you may want to place a WiFi repeater between the PC and the router to help boost the signal.
