Jan 24 16:03:28 dnsmasq-dhcp[494]: DHCPNAK(br0) 192.168.x.x 10:xa:dd:02:e0:xx wrong network
Anybody have any clue what this means ? It was in the system log the mac belongs to my wifes iPhone.
It's normal. Just means the iPhone was on another WIFI network and was assigned an IP there; when it returned to your network it attempted to use that IP on your network -- and your router said "No, I didn't assign that, you can't use it here."
If you had full DHCP logging active, it would have been closely followed by a DHCPDISCOVER process where the iPhone asked for and received a valid DHCP address from your router.
