1. Change DNS to Google/Cloudflare (instructions in section 2.3).

2. Use a VPN (for example, Cloudflare WARP or ProtonVPN).

3. Check whether the router is blocking access to the resource (the "Parental Control" section in the router settings).

3.3 Weak signal or frequent interruptions

If the signal level is low (1-2 bars on the Wi-Fi icon), or the connection constantly drops, try:

Problem Cause Solution
The signal is weak only in some rooms The router is located far away or there is interference (walls, household appliances) Move the router to the center of the apartment or use a repeater
The connection is broken when moving The router is in the enabled mode. 802.11n/ac narrowband (40/80 MHz) Change the channel to 20 MHz or turn on 2.4 GHz instead of 5 GHz
Wi-Fi only works near the router. Weak router transmitter or interference from neighbors Change the Wi-Fi channel in the router settings (use Wi-Fi Analyzer (for workload analysis)
The phone loses network connection in sleep mode MIUI power-saving settings Turn it off Disable Wi-Fi in sleep mode (section 2.2)

⚠️ Attention: If the problem only appears on Redmi, and other devices are working stably, try resetting the network settings on your phone: Settings → System → Reset settings → Reset Wi-Fi, mobile network, and Bluetooth settings.
