Stop joining the wrong network
Why a device picks a network you did not want, and how to send it back.
A device rejoins whichever saved network it notices first. It has no view on which one you meant.
So an old guest network, or your router’s second lane, can win by being seen first.
Key points
- A device rejoins whichever saved network it meets first
- Turning off Auto-Join on the wrong one sends it back
What to remember
- Auto-Join is what a device obeys when it surprises you.
- Devices rejoin from memory. Auto-Join is what to turn off.
Try this
Open the network your device keeps choosing and find Auto-Join. Turn it off and watch where it goes.
