Hello friend!
The default IP address of an NE ranges from 129.9.0.0 to 129.9.0.255 or from 129.9.191.0 to 129.9.191.255.
Change the computer IP address that is in the same network segment as the NE, for example, 129.9.0.N, where N is an integer from 1 to 255. If the IP address conflict is found, replace it with another one. Generally, the probability of this problem is low.
Change the computer subnet mask to 255.255.255.0.
Thank you!
