mine got wireless issue as well.
2g wireless seem failed to launch, and it keep rebooting.
if success to light up, it unable to connect for no reason.
reset, flashing back old firmware, whatever solution try also cant get it to work.

return back to seller and hope for refund.
Mine just happened few hours ago with 5ghz
Initially could not even access the wifi settings without restoring to factory default
Tried off and on the radio didn't work
Tried changing region also didn't work
Tried old firmware also didn't work
The mac address for 5ghz band does not exist
Happened at just three days of usage.
Going to either return it through lazada or arrange a replacement.
What's the update on you guys?
