Why can I access the hotel’s ap network when I connect it to a computer with a network cable, but I can’t access the Internet when I connect it to a wireless router?

The hotel's AP network principle is equivalent to an ordinary wireless router (only more powerful). If the computer can connect to the Internet with a network cable, it means that the hotel's network is normal; if it cannot connect with the wireless router, it means that the fault lies in the wireless router settings (ruling out the cause of router hardware failure).

As shown in the picture: Router 1 is the core router of the hotel, Router 2 is the router to be set, and the gray network cable from Router 1 is connected to the WAN port of Router 2. Router 2 can be set according to the dynamic IP mode. Then set the SSID, encryption method and password. Save and restart.
