Those with a mesh Wi-Fi system will know the universally annoying scenario of walking downstairs into your living room and sitting right next to a secondary mesh node or access point. You then open a video stream only for it to buffer endlessly on a single lagging bar of Wi-Fi. It’s easy to blame your ISP, your router’s range, or even the concrete walls of your home when, in reality, your router isn’t failing to transmit. It’s actually your smartphone that is stubbornly refusing to disconnect. It is trapped in a sticky client loop, holding on to a faint -82 dBm signal from the upstairs router rather than switching to the pristine -45 dBm node just a couple of feet away.
