Change WiFi MAC Address [closed]

Answer 1

The idea of a MAC address is that they are intended to be globally unique identifications. I am not sure how you are seeing the same MAC address across multiple devices, this should never happen. I know it perhaps does not answer your question but it should never happen in the first place.

None the less, you can try MAC address spoofing, and a quick Google search reveals the following link: http://www.robmcghee.com/android/changing-the-mac-address-on-android/

Answer 2

At first you need to be root on your mobile, and open a terminal

~: netcfg -->show yours net devices

Now you can see what device you want to change, then you can do the next steps where eth0 would be replace with your net device name (wlan0 is common).

~: ifconfig eth0 down
~: ifconfig eth0 hw ether 00:80:48:BA:d1:30 --> your new mac
~: ifconfig eth0 up

I think this solution is ok, but now I can't try it. If a solution is possible may be will seem to this.

Answer 3

While I was searching for a more permanent way to change my wifi mac address, I discovered there is a util for Texas Instrument wifi chips. It is called "calibrator". The wifi mac address can set in the nvs file. Here is what I did.

root@android:/system/etc/firmware/ti-connectivity # calibrator set nvs_mac wl1271-nvs.bin xx:xx:xx:xx:xx:xx

I have the HTC Amaze and rooted. You might also need to mount /system with RW. I can't speak for broadcom chips however.
