About Wifi, I rent a house. I live in Hangzhou. There is a network cable for the landlord. Because there is no computer, there is not enough traffic every month.

The first method: plug the wireless router directly behind the original router, and the output of the first router is connected to the input WAN port of the second router. Change the LAN port IP of the second router to a different network segment (for example,192.168.1,and then change it to 192.438+068.0. 1).

The second method: the output of the first router is connected to the output of the second router, and the WAN port is empty. Change the last IP address of the LAN port of the second router to his (for example, the first one is 192. 168. 1, and the second one is192.338+068.1.2-254).
