Hello.
I'm not paranoid or particularly fussed as I've nothing to hide, but I live in a terrace and I do have a next door neighbour who likes to play gaslighting tricks (long story). Let me generalise.
How could a neighbour slam a kitchen cupboard door once against the party wall when my laptop boots up just after I enter my password.
How could a neighbour know to do the same if I unplug my wifi, leave it off for a while and at a random time switch it back on again. It's beyond coincidence and quite a clever trick.
Just wondering if something more sinister like being hacked is at play?
For what it's worth from an oldie, could it be you have your BT wifi available for sharing?
You can opt out of BT wifi sharing in your MyBT although I believe I read once you set it, you will need to wait a day or two.
If this is what your neighbour uses, then you should be able to enjoy a peaceful life without banging cupboard doors.
Did you see something like below, followed by a button?
