Hello,
my girlfriend owns a Xperia Z4 Tablet with the latest official Sony android release. However last week after a restart her wifi failed. It cant be activated anymore. Currently the value "02:00:00:00:00:00" is shown as the wifi mac address, which seems like a common andoid problem. I tried several factory resets and restoring with the official Xperia companion tool but nothing helped so far.
Any further suggestions how to fix this issue? ( I wouldn't mind to root the device, if there is a solution which requires it).
