Right. I’ve rerun some of my checks with my alternative setup.
It isn’t the MAC address that my router has an issue with, it connected fine.
There seems to be something missing from the DHCP packet, the uRadMonitor is sending a packet 319 bytes long, while my working test device is sending 324 bytes.
Screenshots posted are from Wireshark & my router’s admin interface. My cloned MAC is clearly showing on the bottom line with addresss .250
