Set wired/wireless network connection in one of the wireless router is the current home/Office user network of the preferred equipment, but for many first contact with wireless router devices such as readers, how to quickly understand and play the wireless router? In fact, to play the wireless router in general readers from the wireless router outside the interface to understand, as long as the understanding of these external interface functions, playing a wireless router is a piece of cake.
One, WAN mouth function detailed
Wireless and wired broadband routers have 1 WAN ports and 4 LAN ports
Wireless routers have 1 10/100mbps adaptive Ethernet interfaces, which are commonly known as WAN (Wideareanetwork, WAN) ports. The main function of this interface is through the twisted pair and the upper Adsl/cablemodem or Ethernet switch, router connection, in order to achieve Internet access. Since the current wireless router WAN port supports the automatic port rollover (automdi/mdix) function, its use of straight-through and cross-stranded cables can be successfully completed and the upper device connection.
General Wireless Router WAN port can support ADSL virtual dial-up (PPPoE), dynamic IP (dynamicipaddress, such as Fttx+lan access, Dsl+lan access, etc.), static IP (staticipaddress, such as the Green Line access) and other broadband access mode. And the powerful wireless router WAN port can also support the special L2TP, PPTP, 802.1x+ dynamic IP, 802.1x+ static IP and other Internet access mode.
to set up the WAN port, you need to enter the IP address of the wireless router in the IE browser's address bar, and then enter a username and password (typically admin) in the Login window, and then you can find similar options such as the WAN port after entering.
a WAN Setup interface for a wireless router
By default, the wireless router's Internet connection is set to dynamic IP. When an ISP (Internet service provider) supports Dynamic Host Configuration Protocol (DHCP) or you make an Internet connection through a dynamic IP address, you can surf the internet without changing this setting. If your ISP assigns a permanent, fixed IP address to your computer, select the image as a "static IP" and then fill in the options with information such as IP address, subnet mask, and gateway address provided by the ISP.
and if you are using ADSL virtual dial-up (PPPoE) Internet access, you need to fill in this option to get your username and password from the ISP and other information. In addition, in order to solve some of the problems because DNS does not set up the Internet, there are some pages can not open, in the advanced settings of this setting, there are generally "manually set the DNS server" option, you could set it to the local ISP the most stable DNS server address.
In addition, some new wireless routers also support VPN (virtual private network, including L2TP, PPTP, etc.), ieee802.1x (including 802.1x+ dynamic IP and 802.1x+ static IP network mode), such as WAN access, The desired reader can also be set on demand.
L2TP or PPTP connection, in addition to fill in the Internet account, the Internet password, also need to fill in the ISP provided by the dynamic IP, static IP and server ip/domain name.
and using 802.1x+ dynamic IP and 802.1x+ static IP Internet access, you need to fill in the ISP provided by the authentication user name and authentication password to pass certification. After logging in if the dynamic IP mode only click the Update button, the wireless router can automatically obtain from the ISP server WAN port IP address information, and if it is static IP, you also need to manually fill in the IP address, subnet mask, gateway, DNS server and other information. Two, LAN port how to use
Wireless routers generally provide 4 10/100mbps or Gigabit Adaptive Ethernet interfaces (commonly known as LAN ports), To facilitate internal wired LAN connectivity, these ports also support commonly used port rollover (Automdi/mdix) features. These interfaces, in addition to directly connecting 4 computers with a wired network card, can be shared or connected to the Internet, and may be connected to a wired extension of the switch and router (using twisted-pair connections from the LAN port of the wireless router to the switch, the broadband router, the LAN port of the wireless router).
generally provides a wide range of settings for LAN ports on the wireless router's web configuration page, including native IP address settings, subnet mask settings, DHCP server settings, client IP address restriction settings, packet MTU settings, and so on. The
Native IP address is the gateway address of the wireless router, which is the Web configuration address. In general, the factory default wireless router IP address is not required to change, but there are exceptions. For example, if you need security precautions, to not allow intruders to easily guess the address, you can change the address to an infrequently used network segment address, such as changing from the default 192.168.1.1 to 192.168.111.254. If because and Adsl/cablemodem adopt the same network segment IP in connection with the generation of loop conflict (such as modem and routers are used 192.168.1.1 as the configuration address), also need to change the address of the network segment is not commonly used.
DHCP server enable and shutdown the primary role of the
DHCP server is to assign the IP address of the LAN port, by default, the wireless router enables the DHCP server feature to dynamically assign IP to the client Address, so when you connect a good wireless router installed network card driver, no need to make any settings (also using the System network card default automatically get IP), the network card can get and wireless routers in the same network segment of IP, and even share the Internet.
and for security reasons, the LAN port can be securely set by using MAC filtering, in the MAC address filtering option, "Enable filtering" to set the filter rule to "MacAccess to the wireless network, "effective" after the LAN computer network card to fill in the MAC address, so as to prevent the computer wireless access to the network.
and MAC address cloning is also a LAN port application category, which can break through (promotional products main products) Some ISPs through registered computer MAC address to authenticate to the Internet, the principle is to solve the LAN-side network card MAC address map to the WAN port. The method is in the ISP certification of the computer, open the wireless Router configuration page, find the MAC address cloning options, click the "clone" can be.
In addition, the wireless router's any LAN port is connected to the LAN port of another router, and the wireless router can be used as a wireless AP or switch. Of course, you will need to turn off the DHCP server functionality built into the wireless router for this purpose. At the same time, the IP address of the wireless router that is the AP should be located on the same network segment as the upper router. For example, the IP address of the upper router is 192.168.1.1, the subnet mask is 255.255.255.0, and the address pool is 192.168.1.100~199. The IP address of the wireless router can then be set to an address in 100~199 (the preferred intermediate address is recommended), such as 192.168.1.50, "OK".
