Disabling the random MAC address on Android: a complete guide

Modern versions of the operating system Android have introduced many functions to increase user privacy, and one of the most notable was randomization MAC addresses. By default, the device generates a random identifier each time it connects to a new network, which makes it difficult for providers and access point owners to track the user's location and actions. However, this function, designed to protect privacy, often causes unstable Internet operation in home and corporate networks.

Many routers are configured to filter devices by a unique physical address, and changing this address leads to a disconnection or complete lack of access to the network. If you are faced with a situation where your phone periodically loses connection or cannot connect to trusted Wi-Fi, the solution lies in changing your privacy settings. In this material we will look in detail at how to disable the use of a random address and return the device to its permanent identifier.

The setup process may vary slightly depending on the version Android and the manufacturer's shell, but the general principle remains the same for most smartphones. You'll need to go into your wireless settings, find the specific access point, and change the privacy setting. Let's look at this process in detail to eliminate any configuration errors.

Why Android changes the MAC address and why disable it

Starting from Android 10Google has implemented mandatory MAC address randomization for all new connections to Wi-Fi networks. Initially, each network equipment has a unique physical address, hardwired into the wireless module chip by the manufacturer. Previously, the smartphone always used this address, which made it easy to identify the device on the network.

Now the system generates a temporary, random address for each new network. This is done so that outside observers cannot track a person’s movements based on the unique signal from his gadget. However, in a home network or office, such protection is often unnecessary and even harmful.

Network administrators often configure MAC filteringallowing access only to a specific list of devices. If your phone constantly changes its “passport”, the router perceives it as a new, unknown device and blocks access. In addition, some parental control systems and traffic restriction apps are tied specifically to a permanent address.

⚠️ Attention: Disabling randomization reduces the level of anonymity in public places. In cafes or airports, it is better to leave this function turned on to make it difficult to collect data about your movements.

There are also problems with connection stability on older routers that do not correctly handle changing identifiers. In such cases, returning to the factory address is the only way to ensure a stable link. Understanding these nuances will help you make an informed decision about security settings.

Step-by-step guide for pure Android and Pixel

If you own a series smartphone Google Pixel or a device with a clean version of the operating system, the setup process is as standardized as possible. The interface here is intuitive, and the necessary options are hidden shallowly in the wireless connections menu. First you need to make sure that the Wi-Fi module is active.

Go to the section Settings and select item Network and Internet. Next, click on category Wi-Fi. A list of available networks will open in front of you. Find the network that you are currently connected to or that you are planning to set up, and click on the gear icon next to its name.

In the network information window that opens, scroll down the list to the "Privacy" section. There you will see a dropdown list with the current value. By default there may be "Use randomized MAC address". You need to change this value to Use device MAC address.

After selecting the desired item, the system may require reconnecting to the network. The device will disconnect the connection for a few seconds and re-establish it, now using your permanent physical address. This is normal system behavior when changing critical network parameters.

Setting up on smartphones Samsung, Xiaomi and other brands

Electronics manufacturers often modify the standard interface Android, adding your own shells, such as One UI from Samsung or MIUI from Xiaomi. Although the operating logic remains the same, the names of menu items and the path to them may differ. Users of these devices need to be more careful when searching for the desired option.

On devices Samsung the path most often looks like this: Settings → Connections → Wi-Fi. Click on the name of your network (not on the radio button, but on the text). In the menu that appears, select Advanced or immediately look for the line "MAC Address Type". Change the value from "Randomized" to "Phone".

Smartphone owners Xiaomi, Redmi and Poco you should act differently. Go to Settings → Wi-Fi. Click on the arrow to the right of the network name. In the list that opens, find the item Privacy. Here the system will offer a choice between “Use random MAC” and “Use MAC devices”. Select the second option.

It is worth noting that on some older versions of shells this function may be called differently or hidden in the advanced IP settings. If you can't find the item you need, try clicking on the pencil icon or the three-dot menu in the corner of the network settings screen.

Brand	Setting path	Option name	Needed value
Google Pixel	Network and Internet → Wi-Fi → Gear	Privacy	MAC address of the device
Samsung	Connections → Wi-Fi → Network name	MAC address type	Phone
Xiaomi / Redmi	Wi-Fi → Network arrow	Privacy	Use MAC devices
Realme / OPPO	Wi-Fi → Network name → Details	MAC confidentiality	Use MAC phone

Solving connection problems after changing the address

Sometimes even after changing the settings correctly, the smartphone refuses to work correctly on the network. This may be due to the fact that the router “remembered” the previous random address and continues to block the device, or there is a conflict of IP addresses on the local network. In such cases, additional diagnostics are required.

First of all, try to “forget” the network on your smartphone. Go to Wi-Fi settings, select the problematic network and press the Delete or Forgetbutton. After that, connect again by entering the password. The system will automatically apply the new type of MAC address during the initial handshake with the router.

If this does not help, the problem may lie in the router itself. Reboot the router by unplugging it from the power supply for 10-15 seconds. This will clear the ARP address table and force the device to re-allocate IP addresses to all clients. Often this simple procedure solves 90% of connection problems.

⚠️ Attention: If you are using a static IP address, make sure that it is not occupied by another device on the network. Changing the MAC address can lead to a conflict if the router has given this IP to another gadget.

In rare cases, resetting the network settings of the phone itself helps. This action will delete all saved Wi-Fi passwords and Bluetooth settings, but will return the network stack to its factory state. To do this, go to: Settings data-i="120">If the router is configured for strict MAC filtering, you may need to go to the router's control panel (usually 192.168.0.1 or 192.168.1.1) and remove the old random address from the list of allowed devices, adding the new permanent address of your phone there. Settings → System → Reset → Reset Wi-Fi, mobile data and Bluetooth settings.

What to do if the router does not see the phone?

If your router is configured for strong MAC filtering, you may need to go into the router's control panel (usually 192.168.0.1 or 192.168.1.1) and remove the old random address from the list of allowed devices, adding your phone's new permanent address there.

How to find out your real device MAC address

To set up filtering on your router or just to check, you may need to find out the physical address of your smartphone. On Android, this information is available in several places, and it is important not to confuse a random address with the real one. The real address usually consists of 12 hexadecimal characters separated by colons.

The fastest way is to go to the About the phone section in the settings. Often there is an item General information or immediately Wi-Fi MAC address. However, in new versions of Android, this section may display the currently used address, which can be randomized if you are connected to the network.

A more reliable way is to look at the address in the Wi-Fi module state before connection to the network or interface. Go to Settings → About phone → General information. Look for the line Wi-Fi MAC address. If it says "Unavailable", turn on Wi-Fi, but do not connect to any network.

You can also use the engineering menu or special applications, but the standard settings are usually sufficient. Write down this address, you will need it to make an exception in the router settings if you use a white list of devices.

Impact on user security and privacy

By disabling randomization, you are deliberately making a compromise between convenience and security. Understanding the risks is important for informed use of technology. At home, where you trust your provider and neighbors, the risk is minimal.

However, in public places, using a permanent MAC address allows stores, shopping centers and advertising networks to build accurate maps of your movements. They can track how much time you spend at a certain storefront, how often you visit a specific establishment and what routes you prefer.

• 🔒 Confidentiality: A random address protects against profiling and collection of data about your habits on public networks.
• 🏠 Home network: A permanent address is necessary for the stable operation of a smart home, parental control and guest access.
• 🏢 Corporate segment: In offices, IT departments require fixed addresses for security audits and access control to company resources.

It is recommended to use a flexible approach: leave randomization enabled for guest networks, cafes and airports, but disable it for your home network and work office. Android allows you to configure this setting individually for each saved access point, which gives the perfect balance.

⚠️ Warning: On some corporate networks, using a randomized address may be considered an unauthorized access attempt by the security system, which will result in your device being automatically blocked by the network administrator.

Frequently asked questions (FAQ)

Are MAC address settings reset when updating Android?

Usually no. The settings are tied to a specific saved network. However, with a major update to the OS version (for example, from Android 12 to 13), the system can reset privacy preferences for all networks to default values, that is, enable randomization. After a major update, it is worth rechecking the settings of important networks.

Is it possible to change the physical MAC address of the smartphone itself?

Without obtaining root access, it is almost impossible to change the factory physical address, since it is hardwired into the memory of the network chip. Software address substitution is possible only at the operating system level (which is what the randomization function does), but a deep change requires special utilities and superuser rights, which is not recommended for ordinary users due to the risk of loss of warranty.

Why did the Internet speed drop after randomization was turned off?

Changing the address type itself does not affect the speed. If you notice a drop in speed, most likely there is a conflict of IP addresses on the network or the router did not process the reconnection correctly. Try rebooting your router and phone. Also check if the phone switched to the 2.4 GHz band instead of 5 GHz when you reconnected.

Does this setting affect the operation of the mobile network (4G/5G)?

No, this setting applies exclusively to the Wi-Fi module. MAC addresses in cellular networks (IMEI and other identifiers) work on different principles and do not depend on the Wi-Fi privacy settings in the Android menu.

How can I return everything as it was if I change my mind?

The process is completely reversible. Go to the settings of the same Wi-Fi network, find the privacy or MAC address type item and select "Use randomized MAC address" (or "Random MAC"). The device will reconnect, generating a new temporary address.
