The advantage of this is that the network devices in room 10 are all in a network segment, which makes it easier to share resources. 2. The wireless router is connected to the WAN port, and each room is routed twice, which will not interfere with each other. This method is recommended for rental housing. The WAN port of each wireless router is equipped with a fixed IP, so that web management can be realized. Gigabit switches are recommended for switches under the light cat.
