Sky Q Mac address

[DazzaGSXR]

Got my Sky Q box replaced today due to a hardware issue.

Connected it to my Google Nest Pro WiFi no problem. In the Google Home app, there are 2 devices showing as Sky Q (neither are the old one!).

I know the Sky Q box has 3 Mac addresses, one for each wi-fi frequency and one for ethernet.

One device is showing the 2.4Ghz Mac address as connected but no IP address.

The other device is connecting to 2.4Ghz WiFi network and the IP address matches that in the settings on the Sky Q box. However the Mac address for that device doesn't match any of the Sky Q boxes Mac addresses.

Totally confused as to why that might be though?
