How to give Wi-Fi from Xiaomi Redmi 9 to another phone: all ways + error solving

Why Redmi 9 doesn’t give away the internet and how to fix it

Are you in a situation where you urgently need to share mobile Internet from another phone, but Xiaomi Redmi 9 stubbornly refuses to work as an access point? Or the speed of the distribution leaves much to be desired? This problem is familiar to many owners of budget Xiaomi smartphones, where the manufacturer often saves on communication modules. In this article, we will analyze all possible ways of distributing the Internet — from a standard Wi-Fi hotspot to hidden functions in the engineering menu, and also find out why the connection can break down after 5 minutes.

The Redmi 9 (M2003J15SC, M2004J19C) is powered by a MediaTek Helio G80 chipset that has restrictions on the number of devices connected at once, and MIUI's firmware has default power-saving settings that can automatically turn off the hotspot when the battery is low, and we'll show you how to get around those restrictions without rooting.

Method 1: Standard Wi-Fi Access Point

The most obvious method is to use the built-in modem feature, but even here there are pitfalls: for example, if you try to share the Internet on another Xiaomi phone, there can be a conflict. IP-Follow the step-by-step instructions:

1. Open the Settings. → SIM-maps and mobile networks.
2. Choose. SIM-The card you want to give away online (if there are two of them).
3. Slip the access point and modem.
4. Activate the Wi-Fi Access Point switch.
5. Click Access Point Settings to Ask: 🔑 Name of the network (SSID) — Latin, no gaps; 🔒 Password minimum 8 symbols, with numbers; 📡 Range - select. 2.4 GHz for better compatibility; ⚡ Power saving mode - turn off, otherwise the point will turn off through 5-10 minute.

If the access point does not appear in the network list on the second phone after activation, check:

• 📶 Signal level - with weak coverage (1-2 division) distribution may not work;
• 🔄 Rebooting your phone – sometimes helps reset your network settings;
• 🛠️ Update of the firmware - in older versions MIUI 12 was an access point bug.

⚠️ Attention: If you use a traffic-restricted tariff, the operator can block the distribution of the Internet. For example, MTS and Beeline limit speeds to 64 Kbps for devices connected through a hotspot. Check the tariff conditions in your personal account.

Method 2: USB-modem (for stable connection)

If Wi-Fi is unstable or the battery is running out quickly, USB-The modem is a great alternative, and it's a great way to distribute the Internet to another Xiaomi, Samsung, or even a laptop, with the main advantage of minimal speed loss (up to 90% of the original) and no connection problems.

Instructions:

1. Connect two phones with cable USB Type-C — USB Type-C (or via adapter).
2. On Redmi 9, go to Settings → About Phone and tap 7 times on the Build Number to activate Developer Mode.
3. Return to Settings → Additional → For developers and enable USB debugging.
4. Then open the Settings. → SIM-maps and mobile networks → Access Point and modem and activate USB-modem.

On the second phone:

• 📱 Enable data transmission by USB (may be called USB-network);
• 🔌 Confirm trust in the device (a request for debugging permission will appear).

Method 3: Bluetooth modem (charge savings)

If you want to give away the Internet for a short time and save battery power, a Bluetooth modem is the best choice. The speed will be lower (up to 3 Mbps), but it will be enough for messengers or mail. The main advantage is that the Redmi 9 almost does not heat up and does not lose charge.

How to set up:

1. Turn on Bluetooth on both phones.
2. Connect devices (Redmi 9 may require input) PIN-code 0000 or 1234).
3. On the handing phone, open the settings → SIM-maps and mobile networks → Access Point and modem.
4. Activate the Bluetooth modem.
5. On the second phone in Bluetooth settings, select the connected Redmi 9 and turn on Internet access.

⚠️ Attention: On some firmware MIUI 13+ Bluetooth modem only works after the Adaptive Battery function is disabled in the battery settings. Otherwise, the connection will break through the battery. 1-2 minute.

💡

If the Bluetooth modem doesn't connect, try to turn on Flight Mode for 10 seconds first, then turn off and re-pair the pairing. This resets the Bluetooth module cache.

Method 4: Engineering menu (for advanced)

If the standard methods don't work, you can try activating hidden settings through the engineering menu, which will help if:

• 🚫 The access point is turned on, but does not give the Internet;
• 🔄 Speed is limited to 1 Mbps;
• 📵 Devices are connected but not received IP-address.

Instructions:

1. Open the phone app and enter the combination: ##4636##
2. Select Phone Information.
3. Scroll down to the Wi-Fi hotspot block and check the settings: Wi-Fi hotspot state – must be Enabled; Wi-Fi hotspot clients – number of connected devices; Wi-Fi hotspot AP band – if Auto is worth, try manually selecting 2.4GHz.

If the access point is not turned on, enter:

##27663368378##

and in the Engineer Mode menu, select MTK Settings → Band Mode. Make sure all LTE frequencies are active (Band 1/3/7/20 for Russia).

Method 5: Applications for Internet Distribution

If the built-in features of Redmi 9 are unstable, you can use third-party utilities.

• 🔧 Set up time-out shutdowns;
• 📊 Monitoring traffic in real time;
• 🔒 Block the connection of unwanted devices.

Top.-3 tested applications:

1. PdaNet+ supports USB/Bluetooth, bypasses carrier restrictions.
2. ClockworkMod Tether does not require root, but only works via USB.
3. Portable Wi-Fi Hotspot – allows you to change the Wi-Fi channel manually (useful in the face of interference).

⚠️ Note: Apps like FoxFi or Barnacle may not work on Redmi 9 due to MediaTek restrictions.

💡

The app side doesn't increase the actual speed of the distribution, it just optimizes the stability of the connection, and the top speed is still dependent on your tariff and network coverage.

Solving common problems

Even after setting up correctly, the access point on Redmi 9 can malfunction.

If none of these methods helped, check:

• 📱 IMEI — If it resets (shows null), the access point will not work;
• 🛡️ Antivirus – some (e.g. Avast) block distribution as “suspicious activity";
• 🔧 Modem mode in settings SIM — Some operators (e.g. Tele2) need to manually activate the option "Data Transfer".
