D7000[v1] or D7000v2? Look for "Model" on the product label.
Firmware version? Connected to what?

Which "the MAC addresses"? What, exactly, did you "notice", where,
exactly?

How, exactly, did you determine that?
"not" is not a useful problem description. It does not say what
you did. It does not say what happened when you did it. As usual,
showing actual actions (commands) with their actual results (error
messages, LED indicators, ...) can be more helpful than vague
descriptions or interpretations.
> [...] I have the MAC address written down for the functioning channel.
That's nice, but, with my weak psychic powers, I can't see any of
what you're seeing.
> Will firmware installation sort this ?
I doubt it, but I don't know what "this" is, any more than I know
which firmware version you have now.
