Most modern wifi routers or access points (APs) allow you to specify at least two hotspots: One for the 2.4GHz spectrum and another for the 5GHz spectrum.
I use my hotspot names to send social messages to my neighbours. To someone upstairs who smoked indiscriminately, I have one AP set to StopSmokingOutYourWindow.
This might seem passive-aggressive, but it seems to have worked because I no longer smell second-hand smoke late at night. That or the smoker might have died from lung cancer.
To a lady downstairs who prepares an assortment of agonizingly smelly fish every day over a charcoal fire, I direct AuntieYourFishStinksUpOurHome.
I have only just started this second message. Old auntie might not realize that her method of cooking is dangerous when done indoors. She is equally unlikely to surf while she stinks, but her younger flatmates might get the message.
If anyone tells me to be more tolerant, I invite them to stay in my apartment. The smell slaps me awake in the morning, sticks to the laundry and other fabrics, and is nauseating. Someone needs to stop or otherwise compensate me for sleep deprivation, the cost of rewashing clothes, and buying Febreeze. Lots of Febreeze.
