Why Does My PS5 Pro Interfere with My Home WiFi?

Have you checked if your router has QoS settings enabled? Sometimes, enabling Quality of Service can do weird things to the network, especially if it's prioritizing gaming devices. This could lead to problems for other devices while the PS5 is active. It's worth a look!

It's possible that your PS5 and modem are sharing the same electrical circuit. When you power on the PS5, it might cause a power drain that affects how your modem operates, similar to a scenario where powerline adapters cause issues. If you can, try testing the PS5 in another location. If it works fine there, this might be the culprit. Also, look for any signs of a 'brown out' in your home electrical system, where power dips can lead to devices struggling to function properly.

It sounds like you might be dealing with some electrical interference. From my experience, when a device like your PS5 has a poor electrical connection, it can send out interference that disturbs your WiFi signal. This happened to someone I know with a modem on the ground floor that went haywire whenever a nearby device was active. I suggest trying a different power strip or plugging your PS5 into a different wall outlet to see if that changes anything. If the problem persists, you may want to look into warranty repair options.
