Anyway, back to the point - I marched upstairs and had angry words with W, told her that I had seen her other phone, that it was completely disrespectful what she was doing, and that I had told her I would block her phones for 24Hrs.
Oh, and I forgot the icing on the cake. Turns out I don't know what the MAC address is for her new phone so I can't block it from the home WiFI for 24hrs anyway, so no consequence to enforce my boundary. Yes. I did say [Censored] to myself quite a bit once I worked that out.
