1. Close the Mi Home app completely.
2. Open a browser on your phone (Chrome/Safari) and go to 192.168.31.1.
3. Log in using the router admin password (sticker under router).
4. Go to Guest Wi-Fi.
5. Delete any existing Guest configuration (Disable, Save, then Enable fresh).
6. Configure using the browser only—do not use the App for this specific setting.
7. Once saved via web, the App will reflect the changes correctly.

The Fix (NVRAM Reset via SSH - Advanced):

• Single radio shared: Guest and main Wi-Fi share the same 2.4 GHz radio → potential throughput halving.
• No VLAN tagging in stock firmware: Cannot separate guest traffic for managed switches.
• No per-device time limits without Mi Home app (cloud-dependent).
