You'd probably want to follow the manufacturer instructions to do a factory reset on the Powerline hardware, as it may be retaining an IP address which is not appropriate for the new router.

@Timo4 If you also know the IP off the Wireless TP-Link Node connected to the system then you can web manage to that by http ://192.168.0.???/ just remove the space between the p and the colon to do so! My two WPA4220 were .22 and .23 to get to those!
Think your MySky app would show you the assigned IP but not sure, never used it!
