IM A830L Wifi Mac Address

Hi,

First of all sorry about posting in English. I have 2 A830L phones, but both have same Wifi MAC address. So I cannot browse Internet on wifi if both phones have wifi turned on as I get duplicate MAC address on my router.

This happened because I restored the recovery backup of one phone on another. Please someone help me to chnage the MAC address on atleast one of the phone.

Thank You
