Analysis and solution of IP conflict between wireless router and modem in home internet

Summary: Some problems of home Internet access are analyzed and solved.

One, wireless router

A wireless router is a router that is applied to a user's internet and has a wireless overlay function.

The wireless router can be viewed as a transponder, which forwards the broadband network signals from the home wall to nearby wireless network devices (laptops, WiFi-enabled phones, etc.).

Popular wireless routers in the market generally support dedicated line xdsl/cable, dynamic XDSL,PPTP Four kinds of access, it also has some other functions of network management, such as DHCP service, NAT firewall, MAC address filtering and other functions.

The wireless router (Wireless Router) is like an extended product that combines a simple wireless AP with a broadband router, not only with all the features of a simple wireless AP, such as supporting a DHCP client, supporting a VPN, firewall, supporting WEP encryption, and so on, but also including network address translation ( NAT) feature to support network Connection Sharing for LAN users. It can realize the Internet Connection Sharing in the home wireless network, realize the wireless sharing access of ADSL, Cable modem and community broadband. Wireless routers can be connected to all Ethernet-connected ADSL modems or cable modems, or they can be accessed via a LAN mode such as switch/hub and broadband router when used. Its built-in simple virtual dial-up software, can store user name and password dial-up Internet, can achieve dial-up Internet access to ADSL, CM, etc. to provide automatic dialing features, without the need to manually dial or occupy a computer to do server use. In addition, wireless routers generally have a relatively more complete security protection function.

Second, Modem

Modem (English: Modem,modulator-demodulator), it is a digital signal modulation to analog carrier signal transmission, and demodulation received analog signals to obtain digital information of electronic devices. The goal is to generate analog signals that can be easily transmitted and to restore the original digital data by decoding it. Depending on the application, modems can use different means to transmit analog signals, such as using fiber, radio or telephone lines.

Now the modem general integrated router function.

Iii. issues

When the home is online, the IP conflict between the wireless router and modem, and the dynamic IP address can not be allocated.

Iv. Methods of Settlement

Modern families use the network is generally ADSL or optical fiber, for both of these ways, they have such a feature, they need to carry out digital signals and analog signals or optical signals between the conversion. Therefore, in order to realize this kind of conversion function, the network operator usually uses modem.

In addition, modern families often have a number of equipment, such as PC, TV, etc., so, if only using modem only to achieve a single device access network, and can not achieve multiple devices access network. Therefore, in order to solve this problem, modern modem general integrated router functions, so that through the modem access to the extranet and then routed into the intranet.

Generally speaking, when we need to set up a wireless network, the wireless router setting is an extranet-intranet-Wireless WiFi intranet process.
