when I called **1 it tell me my obi110 IP is 192.168.10.252, but I ran a network scanner it turn out to be 192.168.10.251 ! I have set the obi110 IP to be 192.168.10.252 originaly, but somehow it changed to 192.168.10.251 after reboot, this is weird, and I can not logon the neither IP address, I can ping 192.168.10.251 but can not ping 192.168.10.252
