Why Xiaomi Access Point is Not Enabled: A Complete Elimination Guide

When Xiaomi’s smartphone refuses to share the Internet, it is often taken by surprise, especially when you need to urgently connect to the network from a laptop or tablet. The slider in the menu simply does not respond to the press, lights gray, or the inclusion occurs, but the connected devices do not see the network or receive IP-address.

The problem can be either software failures of the MIUI or HyperOS shell, or limitations on the part of the mobile operator, often caused by incorrect APN settings or conflicting energy saving parameters, and in this article we will discuss in detail the algorithm of actions that will help restore the Wi-Fi module to modem modem operation.

Before we get to the tricky part, it's important to understand that the Internet distribution function requires a stable radio unit, and if you have trouble getting the signal normally, the access point mode won't work, so the primary diagnostics always start with checking the underlying link.

Checking basic settings and network status

The first step should always be to check the availability of mobile Internet, make sure that the device is on data transfer and the corresponding indicator of 4G or 5G is on. Without an active connection to the operator’s network, the access point function cannot technically be activated by the system.

Sometimes the problem is solved by simply rebooting the radio, which is to try to turn on the flight mode for 10-15 seconds and then turn it off, and this action forcefully re-registers the device on the operator's network and updates the network settings, which often eliminates temporary glitches.

Also worth paying attention to the balance of the personal account. Many operators block the ability to distribute traffic or access to the Internet itself when the negative balance or the main package of gigabytes is exhausted.

It’s important to check if there’s a traffic limit in the smartphone settings themselves. Xiaomi’s system has a built-in traffic monitor that can block features that consume a lot of data if you reach the threshold you set.

Frequency and Wi-Fi range conflicts

One of the most common reasons why other devices don’t see your access point is the incompatibility of frequency bands.Modern Xiaomi smartphones by default often use the 5GHz band to ensure high data rates.

But many older laptops, tablets, and budget gadgets simply don’t have modules to run at 5GHz, and for them, the network in this range is physically invisible, and you have to force the access point to switch to 2.4GHz.

To do this, go to the access point settings menu. Find the frequency range item (often hidden in the optional menu or called "Setting up the Wi-Fi hotspot"). Change the value from 5.0 GHz to 2.4 GHz and save the changes.

Once you change range, try re-energizing modem, and if the problem was that the receiving devices were incompatible, they'd immediately detect your network.

APN settings and protocol type

If the access point is turned on but the internet on the connected devices is not working (the pages are not loaded, although the connection is there), the problem almost certainly lies in the access point settings (APN).

You need to go to the mobile network settings, select your SIM-map and go to the menu "Access points (APN)". Find your operator’s active access point (usually marked with a green dot) and open its settings.

Inside the settings, find the "APN type" field. The default box may be default, supl, or default. To get the Internet to work properly, you need to add a dun value. The bottom line should look something like this:

default,supl,dun

Note that the values are separated by commas without spaces. After making changes, be sure to click Save (often hidden in the three-dot menu in the corner of the screen) and restart the smartphone.

In some cases, it helps to create a new access point from scratch. Click "New access point" or "Create APN", copy all the parameters from the existing active point, but in the type field, be sure to write dun. Activate the new entry and check the work.

💡

If the "APN Type" field is not available for editing, try resetting the APN settings to factory via the menu in the upper right corner of the screen, and then re-register the dun option.

Restrictions on the part of the mobile operator

It should be borne in mind that many mobile operators’ tariff plans contain hidden or explicit restrictions on the distribution of the Internet (tethering). TTL (Time to Live in passing data packets.

When you give away the internet, the TTL packets from the connected device are different from the TTL packets of the smartphone itself. The operator sees this difference and either blocks the connection or starts to charge traffic at a separate, often more expensive, tariff.

To circumvent this restriction at the level of the smartphone Xiaomi requires a change in the system value TTL. This is done through an engineering menu or ADB-commands, however, require root rights or specific settings depending on the version of Android.

⚠️ Note: Changes in network system settings may cause mobile internet to be unstable or service to be blocked by the operator. Use circumvention methods only if you are confident in your actions and the terms of your tariff.

The operator can also block the distribution if you use it. SIM-A card designed only for modems or tablets, inserted into a smartphone, in which case only a change in the tariff for a universal device will help.

How to change TTL to Xiaomi without Root?
On some versions MIUI (Especially Chinese) there's a hidden engineering menu ##4636## or ##64663##. Find the "Phone Information" or "Usage statistics" section. If you're lucky, there'll be a field to install. TTL. If not, you will need to enter commands through ADB On the computer: adb shell su -c"iptables -t mangle -A POSTROUTING -j TTL --ttl-set 65".

Failures in the system and network modules

Software errors in the MIUI shell can cause network services conflicts. If the access point slider "flys" back to the off state immediately after activation, this is a sign of a service reset.

This procedure will not delete your personal data (photos, contacts), but will reset all stored Wi-Fi passwords, Bluetooth settings and mobile network settings.

Resets can be done along the way: Settings → Connection and Sharing → Reset Wi-Fi, mobile networks and Bluetooth → Reset settings.

Once you reboot your phone, you’ll need to re-enter passwords from known Wi-Fi networks, but the communication module will run in a “clean” state, which often solves the problem.

Hardware problems and firmware version

Physical malfunctions are not excluded: if the antenna module is damaged (for example, after a fall), the phone can hold the network, but can not cope with the load while transmitting and receiving data, which is required for an access point.

It's also critical to keep firmware up to date. Older versions of MIUI may have had bugs that were patched in security patches or major updates. Check for updates in the About Phone menu.

On the other hand, if the problem appeared immediately after the update to the new version (for example, the transition to HyperOS), it may be a bug of the firmware itself, in which case it is worth reading the feedback of other users of your model on the forums.

💡

If nothing helps, try installing a third-party app to create an access point from Google Play.They use their own drivers and can bypass MIUI system limitations.

Impact of energy saving and third-party applications

Xiaomi’s aggressive battery optimization system can force the access point to be turned off to save charge, especially if the smartphone screen is out.Check the battery settings and make sure there is no background activity limit set for network system services.

Also, there may be conflict with memory cleaners or antiviruses that block incoming connections as suspicious.

If you use VPN-services, they can also block the creation of a local network. VPN Check the access point in “clean” mode.

Hidden roaming setup
Sometimes it helps to enable the option "Always allow roaming" in the settings SIM-This makes the module more active in looking for available communication channels.

Details of diagnostics through the engineering menu

For advanced users, a deeper level of diagnostics is available, and by entering ##4636## in the dialer, you can access the testing menu, and you can see the connection status and force the desired network type to change.

Try switching network mode from LTE/TD-SCDMA to LTE only or vice versa, sometimes fixing to a certain communication standard stabilizes the module and allows the access point to start.

However, be careful: incorrect settings in this menu can lead to a complete loss of communication, which will have to be corrected by resetting settings or flashing.

⚠️ Attention: Engineering menus are designed for developers, changing the parameters of the radio module without understanding their purpose can lead to unstable operation of the phone!

FAQ: Frequently Asked Questions

Why does the access point turn off when the screen goes off?
This is the job of the power saving function. Go to the access point settings and find the option "Time out" or "Unplug in the absence of connections." Set a value "Never" or maximum time. Also check whether the background activity restriction is worth it for the system process Wi-Fi.
Can I give away Wi-Fi through the USB-cable?
Yeah, it's often a more stable way. Connect your phone to your computer with a cable, go to Settings. → Connect and share (or “Additional”) and include the item USB-The computer will define it as a wired network connection.
How many devices can be connected at the same time?
By default, MIUI allows you to connect up to 10 devices, which is a limitation you can find in the access point settings. However, the actual number depends on the CPU load and the temperature of the smartphone; with a large number of connections, the phone can warm up a lot.
Why is the 4G icon burning, but the access point does not give away the Internet?
Most likely, the problem is in the settings of APN (no dun option) or the operator blocks the distribution. Also check if the main traffic pack is not out, since many operators after exhausting the limit leave access only to messengers, blocking the rest of the Internet.
Does the Android version affect the access point?
Yes, Android 12, 13, and 14 have changed security protocols (WPA3). If the old device can't connect, try changing the encryption from WPA3 to WPA2/WPA3 Mixed or just WPA2 in the AP security settings.
