When using a signal extender, the router turns off the device's LAN.

At my home, the Internet is connected to a router with a Tp-Link TD-W9960 modem (software version 1.4.0 0.8.0 v009d.0 Build 220621 Rel.58110n). A game console and a smart TV are connected to this router via LAN ports. Due to the fact that the Wi-Fi signal strength is not enough to cover the entire living area, a Tp-Link TL-WA854RE signal amplifier was purchased. The signal booster connected to my router without any problems and expanded the coverage area of the Wi-Fi signal, but there were problems with LAN devices; they stopped accessing the Internet. If you disable the signal extender, Internet access returns to LAN devices. If you view the connected devices to the router when the signal extender is connected, wired clients (LAN) are displayed as connected. I reset both devices (router and signal extender) to factory settings, but that didn't help. Please tell me what could be the problem and how to solve it?
When the signal amplifier is connected, the router's Wi-Fi does not have access to the Internet.
Reconnecting local devices to other LAN ports does not help.
The signal amplifier was configured via the web interface. I did not set up a static IP address, I connected it solely according to the instructions from the quick setup.
Smart TV displays the following connection information:
