Only the living room is in danger, and I want to watch cable TV in the bedroom, what should I do

In fact, there is no need to rematch, you can directly wirelessly bridge the router in the living room, that is, input the router parameters of the living room into the router in the bedroom, amplify the signal of the router, even in the bedroom, it will be like in the living room, the signal is full, and the network speed is smooth! If the broadband or optical fiber you applied for at that time was connected to all the sockets in the house, and the operator also gave dual broadband, or multiple broadbands, your idea can also be realized, and you can set a different wireless name and password from the living room! I hope it helps you and adopts my answer, thank you!

The network cable on the wall cannot be used directly, in the place where the fiber optic home in your home, there is a place where the network cable of the whole house converges, find the specific one on the network cable on the wall, so that you can connect this network cable to the router or optical modem, then you can access the Internet from the network port on the wall.

The main thing is to see if it is sealed. If there is a gap, this space needs to be considered.

It is recommended that you put aloe vera, bamboo, etc. in the bedroom, and it is good to place dangling pothos, ivy, spider plant, etc. in the living room, but you must be careful not to put too much, I hope my answer can help you.
