How to connect a laptop to Wi-Fi using a Redmi 9 phone

Modern smartphones such as Redmi 9Mobile phones have long since ceased to be mere devices for making calls and have become powerful tools for setting up temporary networks. Situations where landline internet is unavailable or unstable require a fast and reliable solution for accessing the global network from a laptop. Using a mobile device as a router allows you to instantly establish a connection without purchasing additional equipment.

Setting up a hotspot in MIUI doesn't require extensive technical knowledge, but it does have its own nuances that affect connection stability. Properly configuring the frequency range and security standard will ensure not only the connection but also the security of transmitted data. In this article, we'll cover all the steps involved in setting up a wireless network between your device and computer.

Preparing Redmi 9 for modem mode

Before activating data sharing, make sure the SIM card is installed correctly and there are funds in your account or an active data plan. Without active mobile data, your phone will not be able to broadcast a signal to external devices. Check the signal strength in the status bar: for comfortable operation, it's recommended to see at least 3-4 bars of the network level.

An important step is to check the module's status. Wi-Fi On the smartphone itself. It should be enabled even if you plan to share mobile data, as this radio module is responsible for creating wireless coverage. Go to Settings and make sure the Wireless Networks slider is turned on.

It's also worth paying attention to your battery. Hotspot mode significantly increases your device's power consumption, heating up the processor and quickly draining the battery. If you're planning a long work session, it's best to connect your phone to a charger or power bank.

Setting up a Wi-Fi hotspot in MIUI

The interface of the MIUI shell installed on Redmi 9, offers flexible settings for creating a personal network. To access the desired section, open the settings menu and find "Access point and tethering." This is where all the tools for managing external connections are located.

First, you need to set a network name (SSID) and password. By default, the system may suggest a standard phone model name, but for security and easier identification, it's best to create a unique name. The password should be complex enough to prevent neighbors or passersby from connecting to your network without permission.

  • 📡 Click on “Wi-Fi hotspot setup” to enter the configuration menu.
  • 🔒 In the "Security" field, select the protocol WPA2 PSK, which is the most secure encryption standard at the moment.
  • ⚡ Set a traffic or usage time limit if you want to control your mobile internet usage.

The frequency band selection deserves special attention. You can switch between 2.4 GHz and 5 GHz in the settings menu. The 5 GHz band provides higher data transfer speeds, but has a shorter range and is less effective at penetrating walls. For a laptop located close to your phone, this option is preferable.

Alternative ways to distribute Internet

If your wireless connection is unstable or the speed is not satisfactory, Redmi 9 offers other data transfer options. The most reliable method is using a USB cable. This allows you to simultaneously charge your phone and transmit an internet signal with minimal latency.

To enable USB modem, connect your phone to your laptop with a high-quality cable. In the hotspot settings menu, select "USB modem" and enable it. Your computer will automatically detect the new network connection as a wired Ethernet network.

Another option is distribution through BluetoothThis method is significantly slower than Wi-Fi and USB, but can be useful in emergency situations when other interfaces are unavailable. To do this, pair the devices via Bluetooth and enable "Bluetooth tethering" in your phone's settings.

Comparing connection methods will help you choose the best option for your situation:

Parameter Wi-Fi hotspot USB modem Bluetooth
Speed High (up to 100+ Mbps) Maximum (stable) Low (up to 2-3 Mbps)
Energy consumption High Charging your phone Average
Convenience Wireless Requires cable Complex setup
Number of devices Up to 10 1 (laptop) 1-2

Solving common connection problems

Despite the simplicity of setup, users may encounter difficulties. A common issue is that the laptop connects, but the internet doesn't work. This may be due to incorrect DNS or APN settings on the phone itself. Check that websites are open in the smartphone's browser.

Another common issue is constant disconnects. This is often caused by MIUI's power-saving algorithms, which can put the radio module to sleep to conserve power. It's important to prevent the system from disabling Wi-Fi in the background.

How to prevent Wi-Fi from disconnecting?

Go to Settings → Battery → Troubleshooting (or the three dots in the corner) → Settings → Enable "Keep Wi-Fi on during sleep." You can also enable "Always keep Wi-Fi on" in the hotspot settings.

If your connection speed is critically slow, try changing your location. Walls, microwaves, and other electronic devices can cause interference. Moving to a window or open space can significantly improve signal quality. 4G/LTE.

⚠️ Note: The MIUI interface is subject to update. The layout of menu items may vary slightly depending on the firmware version. If you don't find an exact match, look for synonyms or similar icons.

Optimizing connection speed and security

For best performance, we recommend manually selecting your network type in your mobile network settings. Go to the "SIM cards and mobile networks" section and select your preferred network type, such as LTE preferredThis will prevent switching to slower 3G in areas with poor reception.

Data security is paramount when using public communication channels. When sharing an internet connection, ensure your laptop's firewall and antivirus are enabled. Do not transmit confidential banking information over open secure connections unless you are confident in the strength of your password.

  • 🛡️ Use complex passwords that contain mixed-case letters, numbers, and special characters.
  • 📉 Disable automatic updates for your operating system and large applications while using a mobile network.
  • 👁️ Regularly check the list of connected users in the hotspot menu on your phone.

Frequently Asked Questions (FAQ)

Why doesn't my laptop see the Redmi 9 hotspot?

Check that network visibility is enabled in the hotspot settings. Make sure your phone isn't too far away. Also, try switching the frequency band from 5 GHz to 2.4 GHz, as some older Wi-Fi adapters don't support the new standard.

Does the phone get very hot when sharing the Internet?

Yes, this is normal. The processor and radio module are working in enhanced mode, converting the signal. We recommend removing the case for better heat dissipation and not covering the phone while it's in use.

Is it possible to share Wi-Fi if the phone is connected to Wi-Fi?

On most modern versions of Android and MIUI, this feature is limited. A phone typically can't simultaneously receive Wi-Fi and broadcast it (in repeater mode). It simply broadcasts mobile data. However, some models allow you to broadcast the Wi-Fi signal via USB or Bluetooth.

How do I find out who is connected to my network?

Go to the hotspot settings on your Redmi 9. This usually displays a list of connected devices with their names and MAC addresses. You can block an unknown device directly from this menu.

Does internet tethering affect call speed?

When using 4G/LTE and VoLTE technology, calls and internet work simultaneously without any loss of quality. If the network switches to 3G or 2G during a call, internet service may be temporarily interrupted.
