Could you share the full IP address of .12, we will do some check and go back to you.
@goCoax 192.168.21.12, I set this up using "static DHCP" From router. I don't have any problems using any other numbers, just the .12 is a problem.
@rroosa We have done check in our lab. 192.168.21.12 works for the MoCA adapter. Please check the attahced pictures.
Please double confirm you can ping the 192.168.21.12 and use 'arp -a' to check the 192.168.21.12 is related to the MAC address of MoCA adapter.
Please change your computer to a fixed IP, for example 192.168.254.12. Then connect your computer to MoCA adapter via Ethernet cable. Should be able to access the admin page.
@Zhe Liu that's not the issue. When I assign .12 to the adapter from my router I can't access web page. All others work. I had to use .13, .14 ect.
