Quick Answer

If your Xiaomi can't connect to BT Broadband, start by checking your BT Hub's lights—blue means it's working; red or orange indicates a problem. Press and hold the Restart button on your Hub until the light turns orange, then wait for it to return to blue. This issue is commonly reported with BT Smart Hub 2 automatic channel selection. Xiaomi smartphones support both 2.4GHz and 5GHz, but some Xiaomi smart home devices only support 2.4GHz—if your BT Hub is 5GHz-only, your Xiaomi may not connect. If you're using a third-party router with BT Broadband (like a Xiaomi router), you'll need to set the WAN connection type to PPPoE with the password "BT".

Before You Start

  • Check your BT Hub lights – A blue light means your Hub is working fine. Red or orange indicates a problem.
  • Check other devices – If other devices can connect, the issue is likely your Xiaomi phone. If nothing connects, the issue is your BT Hub or broadband.
  • Make sure it's after midnight on your switch-on day – If your broadband was just activated, you may need to wait until after midnight.
  • Are you using a third-party router? – If you're not using the BT Home Hub, you may need specific PPPoE settings.

Why Xiaomi Can't Connect to BT Broadband

Understanding why this happens helps you fix it correctly:

Router-Related Causes

  • BT Hub not working – A red or orange light on the BT Hub indicates a connection problem.
  • Channel compatibility – Some 5GHz channels (DFS channels 52–144) can cause instability on Xiaomi devices. Use channels 36, 40, 44, or 48. This issue is commonly reported with BT Smart Hub 2 automatic channel selection.
  • Third-party router configuration – If you're using a non-BT router, you need to configure PPPoE settings correctly. BT recommends using PPPoE with the password "BT" when configuring compatible third-party routers.
  • Special characters in Wi-Fi name or password – Xiaomi devices may not connect if the Wi-Fi name or password contains special characters.

Phone-Related Causes

  • Corrupted saved network profile – The saved Wi-Fi profile on your Xiaomi may be corrupted. Forgetting and reconnecting fixes this.
  • Battery optimisation – Aggressive battery management can interfere with Wi-Fi connections.
  • Network settings corruption – System network settings may need to be reset.
  • HyperOS updates – Some users reported Wi-Fi issues after certain HyperOS updates. Check for the latest HyperOS build.

BT Hub Troubleshooting

Step 1: Check Your BT Hub Lights

Your BT Hub's lights tell you what's happening:

  • Power light is blue – Your Hub is working fine
  • Power light is red – You're not connected to broadband
  • Power light is orange – There's a problem somewhere
  • Broadband light is red – Wrong username/password or line problem
  • Broadband light is flashing red – There's a problem with your broadband line

If any light is red or orange, your Hub isn't working properly. Follow the steps below.

Step 2: Restart Your BT Hub

Nearly all BT Hubs returned as "faulty" are actually working fine—a simple restart usually fixes the issue.

  • Press and hold the Restart button on your Hub until the light turns orange
  • Wait for the Hub to reboot—the light will go green, blue, orange, then stay blue when ready
  • If the light stays red, press the recessed Reset button on the back of your Hub with a paper clip for a few seconds
  • Wait for your Hub to fully restart (2-3 minutes)
  • Try connecting your Xiaomi again

Step 3: If Your BT Hub Still Doesn't Work

If restarting doesn't fix the issue:

  • Check all cables are plugged in correctly
  • Make sure it's after midnight on the day your broadband was switched on
  • If you still have a red light the next day, call BT on 0800 032 2974 (best time to call: between 10am and 6pm)

Xiaomi Phone Fixes

Step 4: Separate 2.4GHz and 5GHz Networks

Most Xiaomi smartphones support both 2.4GHz and 5GHz, but some Xiaomi smart home devices only support 2.4GHz. If your BT Hub uses Smart Connect (both bands share the same name), your Xiaomi may not connect. Separating the networks allows you to connect to the band your device supports.

  • Log into your BT Hub's admin panel (usually 192.168.1.254)
  • Find the Wi-Fi settings
  • Disable Smart Connect or Band Steering
  • Give separate names to 2.4GHz and 5GHz networks (e.g., "BT_2.4" and "BT_5")
  • Save changes and restart your Hub
  • Try connecting your Xiaomi to the 2.4GHz network first

Step 5: Change 5GHz Channel (If Using 5GHz)

If you want to use 5GHz, some channels may cause issues. Change your router's 5GHz channel to 36, 40, 44, or 48 (non-DFS channels) for better Xiaomi compatibility. On BT Smart Hub 2, automatic channel selection often picks DFS channels that cause Xiaomi devices to disconnect.

Step 6: Forget and Reconnect to Wi-Fi

A corrupted saved network profile can prevent connection. Forgetting and reconnecting refreshes the connection.

  1. Settings → Wi-Fi
  2. Tap the gear icon next to your BT network
  3. Select Forget or Forget network
  4. Restart your phone
  5. Reconnect by selecting the network and entering the password

Step 7: Reset Network Settings

This resets Wi-Fi, mobile data, and Bluetooth settings without deleting your personal data.

  1. Settings → Connection & sharing
  2. Select Reset Wi-Fi, mobile & Bluetooth or Reset network settings
  3. Confirm the reset
  4. Restart your phone
  5. Reconnect to your BT Wi-Fi network

Using a Third-Party Router with BT Broadband

If you're using a non-BT router (like a Xiaomi router) with BT Broadband, you need specific settings.

FTTP (Full Fibre) Connections

If you have full-fibre (FTTP with an Openreach ONT), you can connect your third-party router directly to the ONT. BT recommends using PPPoE with the password "BT" when configuring compatible third-party routers.

  • WAN type: PPPoE
  • Username: (leave blank or use anything)
  • Password: BT

Note: If you use BT Digital Voice, you may lose it when using a third-party router.

FTTC (Fibre to the Cabinet) Connections

If you have FTTC, you need a modem as well as a router. The Xiaomi Redmi Ax1800 is a router but doesn't have a built-in modem for FTTC connections.

Known Issues with Third-Party Routers

BT Community forums report that some users have had success using Xiaomi routers with BT Broadband after software updates. If you're using a Xiaomi router with BT, check for the latest firmware updates—some compatibility issues have been resolved in recent HyperOS or router firmware releases.

When to Contact BT Support

Contact BT on 0800 032 2974 if:

  • Your BT Hub light stays red after restart and reset
  • No devices can connect to your BT Broadband
  • Your broadband light is flashing red
  • Your broadband was switched on yesterday but still has an orange light

Best time to call: Between 10am and 6pm for faster help.

Contact Xiaomi UK Support

If your Xiaomi can't connect to BT Broadband but other devices work fine, contact Xiaomi UK Support through the official channels:

  • Xiaomi UK Support website – Official support portal for UK customers
  • Feedback app – Use the built-in Feedback app on your Xiaomi device
  • Xiaomi Community – Post in official Xiaomi community forums, including UK-specific threads

Final Verdict

If your Xiaomi can't connect to BT Broadband, start by checking your BT Hub's lights—blue means it's working; red or orange indicates a problem. Press and hold the Restart button on your Hub until the light turns orange, then wait for it to return to blue. This issue is commonly reported with BT Smart Hub 2 automatic channel selection. Xiaomi smartphones support both 2.4GHz and 5GHz, but some Xiaomi smart home devices only support 2.4GHz—if your BT Hub is 5GHz-only, your Xiaomi may not connect. If you're using a third-party router, BT recommends using PPPoE with the password "BT". If nothing works and your Hub light stays red, call BT on 0800 032 2974.

Quick summary:

  • BT Hub light is red or orange → Restart your Hub; if it persists, call BT
  • Xiaomi can't see the network → Separate 2.4GHz and 5GHz networks
  • Xiaomi sees network but won't connect → Forget and reconnect; reset network settings
  • Using a third-party router → Check PPPoE settings (password: BT)
  • Started after HyperOS update → Check for known Wi-Fi issues; update to latest HyperOS build

Xiaomi Equalizer Settings: Best Sound for Headphones & Earbuds (UK 2026)

How to Boost Headphone Bass on Xiaomi Phones (MIUI Guide for UK Users) Music is closely tied to emotions, and for many UK users, headphones are a constant companion throughout the day—whether commuting in London , relaxing in a Manchester flat, or catching up on podcasts in Birmingham . Naturally, everyone wants the best possible sound quality from their Xiaomi device, without relying on third-party apps that take up storage space. Why Bass Matters Before boosting headphone bass, it’s worth understanding the basics. Humans can hear frequencies from 20Hz to 20kHz. The lower end, below 250Hz, represents bass sounds. Within this range, the lowest frequencies contribute to deep bass, while slightly higher frequencies provide “punchy” bass. MIUI’s equaliser allows you to tweak these frequencies, regardless of the headphone model—be it Mi AirDots , Redmi AirDots S, or higher-end wired headphones. Setting up the equaliser properly is crucial for achieving the richest sound experience...
