Basically, I have an extender for the garden but whenever I go to the garden, my phone remains connected to the extender when I’m back in the house and I can always tell because everything is always slower to load when connecting through it.
How can I make my devices strongly prefer to connect to one SSID when both are there?
You can try and see if Tasker can turn Wi-Fi off and then back on when your extender’s Wi-Fi signal is low.
I used to do this before switching to a mesh Wi-Fi setup.
