The hotel has only one router. Do I need to bring my own network cable?

If you don't have a network cable, you need to bring it yourself. Routers in general hotels will be equipped with network cables. In order to facilitate the guests staying in the hotel to use the network cable for computer connection, it provides a convenient computer internet environment for the guests. Under normal circumstances, the hotel will set up a network cable connection in a corner of the room, and will also be equipped with a computer desk to facilitate guests to connect to the computer. If not, then you need to bring your own.
