I am new to this forum and i would like some help in sorting out the problem described below.
I have a QNAP HS-210 NAS with 2x1TB HDDs setup as RAID1. Firmware updated to version 4.1.3Manual
A few days ago i added a Wifi USB dongle in order to be able to connect the NAS to the second in-house network i have setup.
This dongle is to be used only when required, ie it will not be always connected.
The problem that has now surfaced is that the ethernet MAC address has somehow been replaced with another one and i do not know what has caused it.

The new MAC address is 00:00:00:00:05:09.
I became aware of this change in MAC address the last two times the NAS has been powered up, since it does no longer get the IP address i assigned to it through static DHCP on the router.Qnap Ts-251 Mac Software Manual
The wifi dongle is not connected to the NAS.

The only other change i have made to the NAS since the addition of the wifi dongle is adding the Digital TV Station application along with the QNAP usb tuner.
Can anyone please give me a clue as to what has caused the change in MAC address and if available a step by step method to setting back the original MAC address.
Any help will be greatly appreciated.
Thank you.
