Forget Saved Wi-Fi Networks auf Xiaomi
Wi-Fi settings on your Xiaomi phone store every network you have ever joined, together with its password and connection priority. Over time this list fills up with outdated entries: old routers, previous apartments, or a home network whose password changed after a router reset.
MIUI keeps trying the saved entry first, even after the password changes, so you get stuck with a connection that fails silently instead of a fresh login prompt. Deleting the outdated entry clears the stored credentials and connection priority, so your phone treats the network as new the next time it is in range.
To remove a saved network, go to Tap on Settings ➔ Tap on Wi-Fi ➔ Tap on Additional settings ➔ Tap on Manage saved networks ➔ Choose a Wi-Fi network ➔ Tap on Forget network.
After confirming, the network disappears from your saved list. Reconnect by selecting it among the available networks and entering the current password. This also helps when two networks share the same name but different passwords, a common issue with dual-band routers broadcasting an identical name for the 2.4GHz and 5GHz bands.
If you only want your phone to stop auto-joining a network without losing the password, look for an auto-join option in that network's settings instead. If your connection drops entirely rather than just being slow, this fix likely will not help — check your router or network hardware first.
