Wireless router common function Setup whole diagram

Now hundred yuan can buy a mainstream 54Mbps wireless router, for the family, dormitory or office users want to network, the preferred use of more convenient wireless router is a consensus. However, for beginners to contact the wireless router, how to set the normal function of the wireless router is the key point that they need to grasp urgently.

One, special WAN port Internet access mode

As you know, in order to share the Internet via routers, it is essential to select and set the correct way to access the network in the WAN (Wide area network, WAN) interface. Most wireless routers generally provide 3 types of Internet access: Dynamic IP, Static and PPPoE, and some new models of wireless routers also support L2TP, PPTP, ieee802.1x+ dynamic IP, ieee802.1x+ static IP, and other Internet methods, what are their characteristics, how to set it?

VPN-based L2TP and PPTP

L2TP, PPTP are based on VPN (virtual private network) of the way to access the Internet, it is known to be defined as a temporary, secure connection through a public network (usually the Internet), a secure, stable tunnel through a chaotic public network, an extension of the intranet that can help remote users, Corporate affiliates, business partners, and suppliers establish trusted and secure connections to the company's intranet and secure data transmission.

The PPTP (point to Point Tunneling Protocol, Point-to-Point Tunneling Protocol) protocol separates the control pack from the packet. The control package adopts TCP control, which is used for strict state query and signaling information, the packet part is encapsulated in the PPP protocol first and then encapsulated in the GRE (General Routing Protocol Encapsulation) V2 protocol. L2TP (Layer 2 Tunneling Protocol, second-Tier tunneling Protocol) Agreement is an international standard tunneling protocol. It combines the advantages of the PPTP protocol and the second-tier forwarding l2f (Layer 2 Forwarding, two-layer forwarding Protocol) protocol, which allows PPP packets to be routed through a variety of network protocols, including ATM, SONET, and Frame relay.

When setting up the L2TP or PPTP Internet, the Internet account number and password should be correctly filled in the account number and password provided by ISP, and the IP address or domain name provided by ISP should be filled in according to the dynamic IP provided by ISP, static IP on demand, and server ip/domain name. In addition, can also be selected on-demand automatic disconnection waiting time, on-demand connection, automatic connection, manual connection, such as Internet access, complete changes, click the Save button.

New Broadband authentication Mode 802.1x

As we all know, IEEE 802.1x is a new broadband authentication method based on port access control protocol, which optimizes authentication mode and authentication architecture, solves the problems brought by traditional PPPoE and web/portal authentication methods, and is suitable for broadband Ethernet. The architecture of the IEEE 802.1X protocol consists of three important parts: the supplicant system client, the authenticator system authentication systems, and the authentication server system authentication servers.

And in the ieee802.1x+ dynamic IP and ieee802.1x+ static IP broadband Internet access mode to set, you need to master the following points. If your ISP provides you with ieee802.1x+ dynamic IP access, you can get an IP address from your ISP automatically, and if your ISP provides you with ieee802.1x+ static IP Internet access, your ISP will give you information about the static IP address of the WAN, but either way, First with the ISP to provide you with the authentication user name and authentication password through the IEEE802.1X certification is necessary, then just fill in the landing box to provide the correct authentication user name and password, and then click the Login button, you can login to the server for IEEE802.1X certification.

When the IEEE802.1X authentication login succeeds, if the Update button is clicked dynamically, the router updates the WAN port IP address, subnet mask, gateway, and DNS server settings obtained from the ISP. If the static IP mode, you need to manually fill in the IP address, subnet mask, gateway and DNS server and other information. When all is done, the Internet can surf normally.
