(Suppose a network topology is shown in the figure below. The network uses DSL/CableModem/LAN and other methods to connect to the Internet. Modem or routers share the Internet connection, and the internal network is connected through switches, so that multiple computers can access the Internet. Assuming that the switch has turned on the DHCP function to automatically assign IP addresses, and the IP segment is 192.168.1.0, the IP addresses of computers A, B, and C on the Ethernet are 192.168.1.x (X is any number between 2-255, the same below). ) and can surf the Internet normally. Today, if a wireless broadband router is connected to a node, it is connected to desktop computers such as D and E with network cables, and notebook computers F and G are connected wirelessly. How to set it up to ensure that D, E, F, and G go online together? (D, E are wired connections, F, G are wireless connections))
