[Q] wifi change mac address - Android Q&A, Help & Troubleshooting

Firt, Great site very helpfull. Sorry my english.

Also try with softwares :

-Set MAC adress : cant read mac adress
both don´t ask root right.
Any idea?

You can spoof your MAC using busybox
For instance:

First, you need Busybox and Terminal Emulator installed. And you need root.
After you have that, open up Terminal Emulator and give it superuser permissions by typing
"su" (without quotes)
and press enter. You should be asked if you want to allow it to have superuser access. Press allow
Next, type in
"busybox ifconfig". (make sure your wifi is on first). Look for either eth0 or wlan0. Whichever one is on the list is your wifi device. Keep that in mind.
Next, type in
"busybox ifconfig wlan0(or eth0) hw ether XX:XX:XX:XX:XX:XX"
with the xx's being your MAC address you want to change it to.
Now, this is the important part!
It WILL NOT change your MAC address properly if your wifi is not off first! You must have it off, and then turn it on (through the status bar toggle) and then quickly hit enter! If it says no such device found you must press Volume Up+W to automatically reenter your last command and press enter again until it does not say no such device found.
I find it works best when I do Volume up+W and then hit enter multiple times.
To check if your MAC address has been changed, go to your wifi settings, click the menu key and select advanced. Your current MAC address will be under the MAC address section.
Good luck!

You can also do this without having to use Terminal Emulator by using the adb.
With your device properly setup for development on your pc just type adb shell in your terminal on your pc and then you can enter your busybox commands.This still does require that your root and have busybox installed!

trouble
Hi,
it changes my MAC, however I can’t connect to any wifi network! It always say that the password is bad, or in open networks, it hangs on retriving ip address.
But if I use:
busybox ip link set wlan0(or eth0) address XX:XX:XX:XX:XX:XX
It work at the first time or second.
Insted of turn the wifi off and on and quickly run the command.
I use the terminal with su:
svc wifi disable
svc wifi on
(need to wait 0.5s to proced)
busybox ip link set wlan0(or eth0) address XX:XX:XX:XX:XX:XX
and its done .
it will be great if an app developer can make an app to run this command automatically when we want to connect to wifi. it will make the mac address not permanent but almost.

You must have rooted device and busybox installed. First switch to su and type commands.
