The MAC address is hard-coded on your network interface controller (NIC) and cannot be changed permanently with simple command line from your terminal nor in software level approach. However we can assign a temporary solution for your MAC, which will be reverted back to it's original state after Reboot/Power off .
Requirements :
- Rooted phone
- Busy box app from play store installed
- Terminal emulator from play store :
Know normally your card's interface should be eth0 ( older devices ) or in case of newer phones ( wlan0)
after granting super user permission in terminal ( Su) , type >> netcfg
Code:
busybox iplink show eth0
you may change it to wlan0 , if you are on this interface
Code:
busybox ifconfig eth0 hw ether XX:XX:XX:XX:XX:XX
change the XX to your preference value ( i,e : 00:11:22:33:44:55)
Because of kernel design and absence of monitoring mode support for mac spoofing , this method won't work on protected networks ( ONLY open networks )
and if the lines above don't work for you , try to disable and enable your eth0:
Wifi is ON
su >
Code:
busybox ifconfig eth0 down
busybox ifconfig eth0 hw ether (address)
busybox ifconfig eth0 up

You are trying to access protected network , which comes with encryption ( WEP/WPA/WPA2 etc etc ) ? What error you are getting from Android OS ? Are you absolutely certain your MAC address is white listed inside the router/modem settings on open network protocol settings of course ?

Already explained about protected networks and the reason behind it in the first post . You need to set it to 'Open network' ( means no wpa/wpa2/wep etc,,etc) inside the router/modem you are seeking an access.

Maybe not so
I have tried several apps and every possible command in terminal (as root) and although all can successfully change the MAC address, the device is always unable to connect to an access point thereafter. This is a known issue, but unresolved and too frequently denied. I half suspect their are some "political" purposes for withholding the resolution; many have inquired about this, yet only receive pedantic or useless replies. I wonder if there is any correlation to the wifi chipset, or if it's a built-in Android limitation. I know my chipset is very difficult to identify ('demesg | grep wlan0' yields nothing familiar) and that it also seems incapable of monitor mode.
I have scoured many forums for the solution to this and found only a suggestion to change certain files, all which appear to vary between devices, etc.
What I'd like at this point, is and explanation if not a solution. Anyway, I think the OP may have been misunderstood, ergo my 'two cents'.
