Wisenet Device Manager IP Range Scan Limitation?

[Andrew1975]

Hi, I am using Wisenet Device Manager v. 2.6.7.0, am connected to the network to which my cameras are connected and have my subnet mask set to 255.255.0.0. The device detection scan detects all cameras in the 192.168.1.x range, but does not scan 192.168.2.x. Can anyone help, please?
