One of my raspberry shakes got damaged by a surge on the internet line. At the time I needed the station running so I just swapped the device with a spare unit and took the damaged one home for repairs. I found out that the ethernet port of the pi was damaged so I ordered a replacement pi, installed the shake board and sd card and the system fired up nicely… except that I had one problem. The last 4 digits of the mac address of the pi was the same as one already being used on the network B2:BC. So I ended up with a station with the same name as another station in the network RB2BC.
Is there any way of me reassigning the old R4E13 to this device or even getting a new mac address? I tried changing the mac address with macchanger, changing and preventing the writing of files in the opt/system/sys folder and even reinstall the image file on the sd card but nothing seems to work.
