Many thanks for the replies – the answer to Pete's query is both – wireless and wired.

Thanks

A further reply to pete' – as far as I can tell it shouldn't be possible for the clients that go offline and then come back to be trying to bind to a different subnet when they come back online – the IP Bind table specifies which the ip address (and so subnet) to bind each respective mac address to. But I could be missing something – I'm certainly not an expert . . .

Yes, I did re-read after I posted, and forced two apple, and one android on and off line, via a Ubquiti, which is wired to one of the ports on the 2860, that's how I stumbled on Bind issue I just iterated above.

They all re-connected ok, and I only have two subnets. I will see what happens after the timeout occur, perhaps as you asy, being a bug on multiple subnet configurations maybe?
