Step 3: Set up Wi-Fi for maximum speed and stability

By default, the Xiaomi 3 router uses suboptimal Wi-Fi settings, which can lead to low speeds or connection breaks.

  1. Channel selection: Go to Wi-Fi Settings β†’ Advanced and manually select a channel. 1, 6 or 11 channels are recommended for 2.4 GHz (they do not overlap); for 5 GHz (if any), 36-48 or 149-165 channels (they are less busy).
  2. Channel width: For 2.4 GHz, set 20 MHz (this will reduce speed but increase stability). For 5 GHz, 80 MHz can be used if there are no other networks nearby.
  3. Wi-Fi Standard: In settings, select 802.11n/g/b for 2.4GHz and 802.11ac/n/a for 5GHz. This will ensure compatibility with all devices.
