[FOSCAM] 2 cameras with same MAC address after flash?

Hi everyone,

I own 2 Foscam FI9820W: let's call them camera1 and camera2.
They both have stock firmware.
I made a backup from camera1 and i used it to restore camera2.
Now they both have the same MAC address: how is that possible? (foscam us support says that it should've not happen)
BTW now, when i'm using'em both at same time, connection drops on one or the other one (even if they have both static ip addresses and different ports and connected on LAN)
I would like to change the MAC address of camera1 (or camera2)
How can i do that? Which MAC i should use (i can read 2 MAC addresses on stickers and no one is that one shown by router/cam UI interface)

Please help me
Thank you

Hello,
I have the same problem.
is there a way to change the mac address of an FI9805W.
thanks in advance.

Hi,
wich type of backup did you do? via gui?
Have a look at the file with a hex-editor and search for the actually used mac.
Change it and try flashing this modified abckup.
