Netgear WLAN Repeater no Internet via Lan?

My Wi-Fi repeater is no longer working properly. Suddenly my laptop no longer had a LAN connection, but Wi-Fi still works. I've already reset it. Unfortunately, I do not know the model because of the picture.

Do you have a second computer? Then you could test whether it is the repeater or the LAN of the laptop. Another cable available?

Yes, thank you I will test it
