How to Share Internet from a Redmi 9A: 3 Proven Methods + Troubleshooting

Xiaomi Redmi 9A — one of the most popular budget smartphones, still in active use in 2026. Despite its modest technical specifications, the device performs admirably as a mobile router. But how do you properly set up Wi-Fi sharing to avoid connection drops, slow speeds, or sudden hotspot disconnections?

In this article you will find step-by-step instructions for all versions of MIUI (including the latest updates), ways to save traffic when distributing, as well as solutions to typical problems — from the "Unable to enable hotspot" error to carrier restrictions. We tested all methods on real devices and took into account nuances not covered in standard manuals.

1. Preparing your phone before sharing Wi-Fi

Before turning on the access point on Redmi 9A, make sure your smartphone is up to the task. Failure to meet basic requirements may result in overheating, rapid battery discharge or unstable connection.

Here's what you need to check:

  • 🔋 Battery charge — not less than 30%. If the level falls below 15%, MIUI automatically disables the hotspot to save power.
  • 📶 Mobile network signal strength If you have 1-2 bars, your internet speed will be extremely slow. It's best to move closer to a window or use an external antenna (if supported).
  • 🔄 System updates - come in Settings → About phone → System update and install the latest patches. MIUI 14+ fixes critical Wi-Fi hotspot bugs.
  • 📱 Free memory — If your phone has less than 500 MB of free space, background processes may interfere with the stable operation of the access point.
⚠️ Attention: If you use two SIM cards, the hotspot will only work through the one that is selected as the primary data card. Check this in Settings → SIM cards and mobile networks → Data transfer.

It is also worth considering that Redmi 9A supports Wi-Fi distribution only within the range 2.4 GHz. It means:

  • ✅ Wider coverage range (penetrates walls better than 5 GHz).
  • ❌ More interference from other devices (microwaves, wireless mice, neighboring routers).
  • ⚠️ Maximum speed is limited to ~50 Mbps (even if your plan allows more).

2. Method 1: Standard access point (tethering)

This is the simplest and most reliable method, which works on all versions of MIUI. The instructions are valid for Redmi 9A with firmware from MIUI 12 to MIUI 15 (inclusive).

Steps to enable:

  1. Open Settings (gear icon on the desktop).
  2. Go to the section Access point and modem (in some versions it is called Modem mode).
  3. Tap on Wi-Fi hotspot.
  4. Activate the slider at the top of the screen.

Now let's configure the settings for security and stability:

  • 🔑 Network name (SSID) - change to unique (eg. Redmi9A_YourName). This will help avoid conflicts with neighboring networks.
  • 🔒 Password — Use a combination of 8+ characters, including numbers and letters. Example: Xiaomi2026!Don't use simple passwords like 12345678 - they are easy to hack.
  • 📡 Range - leave it 2.4 GHz (other options on Redmi 9A No).
  • ⏱️ Auto power off - Disable this option if you want the access point to work constantly.
Parameter Recommended value Why is it important?
Security WPA2-PSK The most balanced option between protection and compatibility with older devices.
Frequency band 20 MHz A narrow band reduces interference but reduces maximum speed. Optimal for Redmi 9A.
Max connections 4-5 devices More connections will lead to lag and overheating of the processor. Helio G25.
Hide network No Hidden networks are more difficult to connect and do not add security.

☑️ Check before connecting devices

Completed: 0 / 4

After setup, connect to the created network from another device (laptop, tablet, or second phone). If the internet isn't working:

  • Check if it is enabled mobile data transfer on Redmi 9A.
  • Make sure there is enough money on your SIM card and that the "zero balance" is not activated.
  • Restart your phone - sometimes it helps with MIUI crashes.

3. Method 2: Sharing via USB (for PC)

If you only need to connect your computer or laptop to the Internet, USB modem will be more reliable than Wi-Fi. This method:

  • ⚡ Saves battery power (the phone charges while working).
  • 📈 Provides a more stable speed (no interference from other devices).
  • 🔒 Less risk of traffic interception (data is transmitted over the wire).

Instructions for Windows 10/11:

  1. Connect Redmi 9A to the computer via a USB cable (preferably the original one).
  2. On your phone, select the mode File transfer (not "Charging").
  3. Go to Settings → Hotspot & Tethering → USB Tethering and activate the slider.
  4. On your PC, wait for the drivers to install (you may need to connect to the internet via another connection to download them).
⚠️ Attention: On some versions of Windows 11, drivers for Xiaomi are identified as "Unidentified device". In this case, download Mi PC Suite from the official Xiaomi website and install it.

If the Internet does not work:

  • Check that in Network connections Windows has a new connection (usually called Remote NDIS).
  • Disable your antivirus (sometimes it blocks new network devices).
  • Try a different USB port (USB 2.0 is better, as USB 3.0 may conflict).

4. Method 3: Sharing via Bluetooth (for older devices)

This method is suitable if:

  • Your laptop or tablet does not support Wi-Fi.
  • You want to save battery power (Bluetooth uses less power than Wi-Fi).
  • You only need to connect one device (for example, a smartwatch or fitness tracker).

How to set up:

  1. Turn on Bluetooth on both devices.
  2. On Redmi 9A go to Settings → Connectivity → Bluetooth.
  3. Tap on the name of the device you want to connect to.
  4. After pairing, return to Settings → Hotspot & Tethering and select Bluetooth modem.

Limitations of the method:

  • 🐢 The speed does not exceed 2-3 Mbps (enough only for instant messengers and light websites).
  • 🔌 The distance between devices should not exceed 10 meters.
  • 📱 Only one device can be connected at a time.
Why is Bluetooth modem slower than Wi-Fi?

The speed is limited by the Bluetooth version in the Redmi 9A (4.2). For comparison, Wi-Fi 4 (in this phone) theoretically supports up to 150 Mbps, while Bluetooth 4.2 only supports a maximum of 25 Mbps in practice. Furthermore, the Bluetooth protocol adds latency when transmitting data packets.

5. How to save traffic when sharing the Internet

Mobile Internet on Redmi 9A It gets used up very quickly if there are multiple devices connected to the access point. Here 5 working methods reduce consumption:

1. Speed ​​limitation for connected devices

Download the app from Google Play NetGuard or Internet Speed Meter LiteThese utilities allow you to:
