Hi @Biffobails
If you have already tried to configure the Powerline adapters but no internet, or devices such as PlayStation can not connect to the network, please confirm whether you have encountered the following problematic scenarios:
Case 1. The powerline light is not on after the configuration
Case 2. The powerline light is on after the configuration
Case 3 Only the wireless connection is not working
Case 4. Only wired connection no internet
Case 5. Only specific devices cannot work
Then, it is suggested to follow the article to find possible solutions:
What can I do if I can't have Internet connection after connected to powerline adapter?
Please note that TL-PA717 doesn’t have Wi-Fi function, if you have other extender, please tell me what the model it is?
If your CCTV NVR is connected to Wi-Fi, and you have updated the network recently. You may change Wi-Fi settings of Wi-Fi network, you should reset the CCTV NVR and configure it again with new network. If other devices can work with the new network, it is recommended to contact support of your CCTV NVR.
