Suppose a network topology is shown in the following figure, the network uses dsl/cable Modem/lan to connect to the Internet, the Modem or the router to share the Internet connection, the internal network is connected through the switch, in order to realize more than one computer access to the Internet. If the switch has DHCP enabled to automatically assign IP address, IP segment is 192.168.1.0, then Ethernet Computer A, B, c IP 192.168.1.x (x is any number between 2-255, the same below), and can be normal Internet. Now, if a wireless broadband router is attached to a node, it is connected to a desktop computer such as D and E with a network cable, and the laptop F and G are connected wirelessly. How to set up to ensure that d,e,f,g at the same time online? (D,e for wired connection, f,g for wireless connection)
Wiring method: The cable connected by the switch connects to the LAN port of the wireless broadband router (note not the WAN port), and the D,e desktop computer is also connected to the LAN port without line. At this point the wireless router actually functions as a hub. Wireless broadband routers typically have 1 WAN ports to connect to the Internet interface and 4 LAN ports to connect to a computer with a network cable. In the environment described in this article, the WAN port is essentially not functioning.
Set method: 1. Manually set the computer D and e IP address is 192.168.1.x, network connection-Local connection-Properties-General-internet Protocol-Use the following IP address, IP address: 192.168.1.30 (for example) Subnet mask: 255.255.255.0. Default gateway: 192.168.1.1 Use the following DNS server addresses, preferred DNS servers: 192.168.1.1 Alternate DNS servers: not filled. Setup is complete and the point is determined to save.
2. Notebook f,g settings are similar, the only difference is that we are now configured with a wireless network card, open network connection-Wireless Internet connection (non-local connection)-Properties-General-internet Protocol-Use the following IP address, IP address: 192.168.1.37 (for example) Subnet mask: 255.255.255.0. Default gateway: 192.168.1.1 Use the following DNS server addresses, preferred DNS servers: 192.168.1.1 Alternate DNS servers: not filled. Setup is complete and the point is determined to save.
Note: IP addresses cannot be duplicated. If Computer d is set to 192.168.1.30,e 192.168.1.31, the f,g can only be set to something else, such as 192.168.1.37,g 192.168.1.39.
Configuration complete, OK. You'll find that you have access to the Internet.
