I just configured RV042 (Ver. 188.8.131.52) to use IP address 192.168.1.XX and then connect it with the local network. The problem is that the RV042 will use default IP (192.168.1.1) around 5 sec. when restart the RV042. That will cause duplicate ip in this few sec because another device is using 192.168.1.1. I have tried another RV042 with same version and still have same problem. Thanks!!!
