Wondering whether the following can be implemented on a MikroTik wireless device. I want have to have at least 2 wireless networks - one for office personnel with the same ip address subnet as the LAN; and one for guests, which is isolated from the former.

I see on the forums talk about wireless isolation, but I don't see that anyone is doing two wireless networks on one device.

Is it possible? Maybe it's possible on particular models?

Appreciate the feedback!

I don't see why it wouldn't be possible. Is the guest wireless going to be on the same subnet as the office/personnel lan?

It seems like standard firewall rules will apply to keep them separate. If you'd like to enable client isolation, you'll need to unset the "default forward" option on the SSID.
