Frequently asked questions

How do I remove a saved Wi‑Fi password?
Forget or remove the network from the device. On Windows: Settings > Network & Internet > Wi‑Fi > Manage known networks > select the network > Forget. On Mac: System Preferences > Network > Wi‑Fi > Advanced > remove the network. On phone: Wi‑Fi settings > tap the network > Forget.
Why does my device keep using the old password?
The device caches the password. Until you forget the network, it will keep trying the old one. Forget the network, then reconnect and enter the new password when prompted.
What if I do not know the correct password?
Check the router label for the default, or log into the router admin (192.168.1.1 or 192.168.0.1) to view or reset it. If your ISP set up the router, contact them.
