Wifi Mac Change For Android

If you are surfing the web from your Android phone using a WiFi network, the network adapter of your WiFi devices must have a MAC address to set up the connection and transfer data over the network. MAC address looks something like this XX::XX:XX:XX:XX:XX, where each X is a hexadecimal character i.e. Ranges from 0-9 or A-F. Jun 30, 2020 The MAC address (also referred to as the Media Access Control address) is an identifier consisting of 12 characters that are given to any piece of hardware which can access Wifi internet. So, this means that your network adapter has one, as well as your Android smartphone, phablet, or tablet. #3 How to Change Android Mac Address With Engineering Mode.

Hello Friends This is sanjay sharma and Today i am going to show you how to change Wi-Fi mac number in android mobile phone without root or any software Now.

Starting in Android 8.0, Android devices use randomized MAC addresses when probingfor new networks while not currently associated with a network. In Android9, you can enable a developer option (it'sdisabled by default) to cause the device to use a randomized MAC addresswhen connecting to a Wi-Fi network.

In Android 10, MAC randomization is enabled by defaultfor client mode, SoftAp, and Wi-Fi Direct.

MAC randomization prevents listeners from using MAC addresses to build a historyof device activity, thus increasing user privacy.

Additionally, MAC addresses are randomized as part ofWi-Fi Aware andWi-Fi RTT operations.

Implementation

To implement MAC randomization on your device:

1. Work with a Wi-Fi chip vendor to implement the following HAL methods:

   • IWifiStaIface#setMacAddress: Configures the MAC address of theinterface. The default implementation brings the interface down, changesthe MAC address, and brings the interface back up.
   • IWifiStaIface#getFactoryMacAddress: Gets the factory MAC of wlan0using an ioctl call.
   • ISupplicantP2pIface#setMacRandomization: Sets P2P MAC randomizationon/off in the supplicant.

2. Setconfig_wifi_connected_mac_randomization_supported to true in the Settings config.xml (this can be done in a devicecustom overlay).

   • This flag is used to control whether client-mode MAC randomization isenabled.

3. Setconfig_wifi_p2p_mac_randomization_supported to true in the Settings config.xml (this can be done in a devicecustom overlay).

   • This flag is used to control whether Wi-Fi direct MAC randomization isenabled.

4. Test your implementation using the methods described inValidation.

The System UI must:

• Have an option to enable or disable randomization for each SSID.
• Have MAC randomization enabled by default for all newly added networks.

Use thereference implementation of Settings UI to implement new prompts.

Devices running Android 9 or lower might not havesupport for Wi-Fi MAC randomization. When upgrading such devices to Android10, the Wi-Fi MAC randomization feature can be disabledby setting the WIFI_HIDL_FEATURE_DISABLE_AP_MAC_RANDOMIZATION flag to true inthe Wi-Fi vendor HAL make file.

Validation

To validate that the feature is working as intended, run both an integrationtest (ACTS) and a manual test.

To run an integration test, use the ACTS file,WifiMacRandomizationTest.py, located intools/test/connectivity/acts/tests/google/wifi, to verify that the device usesthe randomized MAC address and correctly stores the randomized MAC address foreach network.

To run a manual test:

1. Verify that MAC randomization is enabled on the device by checking thatconfig_wifi_connected_mac_randomization_supported is set to true in thedevice overlay.
2. Connect to a Wi-Fi network.
3. Tap the network to go to the Network details page. Verify that MACrandomization is turned on. Verify that the MAC address displayed is arandomized MAC, which has the locally generated bit set to 1 and themulticast bit set to 0.
4. Turn MAC randomization off. Connect to the same network and verifythat the factory MAC is being used.
5. Delete the network by tapping Forget on the Network details page.

6. Connect to the same network and verify that the same randomized MACaddress is being used.

   Note: Randomized MAC addresses are generated per SSID and are persistent.

To test MAC randomization on a pre-Android 10 device(capable of supporting MAC randomization) upgrading to Android10 or higher:

1. Have at least one saved network on a device runningAndroid 9 or lower.
2. Flash the Android 10 system image.
3. In the Wi-Fi picker, verify that MAC randomization is turned off for allsaved networks.
4. Turn MAC randomization on. Connect to the same network and verifythat the randomized MAC is being used.

If you are a network administrator, you probably have to deal with mac addresses often. MAC address is required to identify a device on a particular network and manage its connection. Although it’s similar to the device ID, but it’s specifically used for network connection.

You can use it to restrict network access to specific devices, apply network rules, and even change it to spoof a different device. I am sure you can see how important it is to know your device’s MAC address. Therefore, today I will show you 4 ways to find MAC address on any Android phone.

1. Find MAC address from the device information

The quickest way to find MAC address on Android is to look for it in the About device section.

Here’s how to access it:

1. Go to “Settings” and tap on “About device”.
2. Here tap on “Status” and you’ll find the MAC address under the “WiFi MAC address”

You can tap and hold on the MAC address to copy it and paste it anywhere you like.

2. Find MAC address from the WiFi settings

Alternatively, you can also find MAC address from WiFi advanced settings. Follow the below instructions:

1. Access “Settings” and tap on “Connections” (or WiFi and networks) option.
2. Now tap on “Advanced” button at the top-right corner.
3. In the Advanced settings, you’ll find the MAC address at the bottom.

3. Use a dialer code to find MAC Address

If you are one of those geeky users who like using codes, then you’ll surely like this option. Like many other secret Android codes, there is also a dial pad code to find MAC address on Android. Here’s is what you need to do:

Open up the dial pad (the app you use for calling) and enter the code *#*#232338#*#*. A tiny window will open up to show your mac address.

Note: This trick may not work on some Android phones. For example, it doesn’t work on my Samsung device.

4. Use a MAC address finder app

If you frequently need to look for the MAC address of your Android phone, then using a dedicated app might be a better option. There are many apps for this purpose, but I recommend What’s my MAC address for its simplicity.

Just install and launch the app and it will show the device MAC address on the top. Additionally, it also shows SSID and BSSID (WiFi MAC address), which could also be useful in many situations. If you need to copy any of the information, just tap and hold on it.

Ending thoughts

These are all the methods I know to find MAC address on Android devices. I particularly like the first method on this list as it’s easier to access and you also have the option to copy the MAC address. If you know any other ways to find MAC address on Android, let us know in the comments below.
