How can you tell if two of your sockets are on the same phase?

I’m planning on buying a powerline adaptor for one of the upstairs bedrooms. This is to allow for a stronger internet access from this room as the WiFi signal is almost completely blocked by an external wall due to it being an extension. My Wifi router is downstairs in my living room and I’ve looked at other option such as a WiFi repeater but this wouldn’t work in my situation. I would also like to avoid running ethernet cables through my house. I’ll attach an image of my circuit breaker to see if anyone can help me see if they are on the same phase. Any help would be appreciated.

You have a single phase install, so all your sockets will be on the same phase. They may be split across different circuit breakers though.

Thankyou.
