3G routers use can be divided into industrial 3G router, commercial 3G router; divide up from LAN speed wifi, 3G router is divided into 54M, 150M, 300M and so on. Router hardware includes RAM / DRAM, NVRAM, FLASH, ROM, CPU, motherboard and power supply as well as a variety of ports. General hardware failure can be seen from the LED. For example: There is a green PWR (or POWER) status indicator on the power supply module. When this LED is lit, indicating that the power is working. Router Passwords There are two places you need to set. From the previous description can know there are two basic access mode to access the router: user mode and management mode. For safety reasons, when entering these two modes are required to set a password. Although we all know the password key is to have the largest administrator privileges, but still some people will forget it. Someone even set a password too simple to malicious hackers to enter and modify the password. In fact, if we look carefully that these low-level errors are avoided. In case the password is lost Wuhu wireless router brand, do not be afraid Wuhu wireless routers, which provides password recovery methods. In addition to the two basic router access mode (user mode and management mode), there is a RXBOOT mode, in this mode you can easily restore the router password. Of course, in order to enter only after the computer via CONSOLE port HyperTerminal connection is established. Some routers also on the panel to provide a more convenient RESET button, just reset a few times, you can restore the original password. Wireless Router: A router is a multi-port device that can connect different transmission rates and run on a variety of LAN and WAN environments, you can use different protocols. Router that belongs to the third layer of the OSI Model - network layer. Guide data from one network to another network, but also to guide the transfer of data from one network to another network. First, the network interconnection: router supports a variety of LAN and WAN interfaces, mainly for the interconnection of LANs and WANs, to achieve mutually different communication networks; second, data processing: provide, including packet filtering, packet forwarding, priority, reuse , encryption, compression, and firewall functions; Third, network management: router includes a router configuration management, performance management, fault management and traffic control. The so-called "routing" refers to the transfer of data from one place to another, behavior and action, and a router, it is the action to perform such acts machine, its English name is Router, is a kind of connect multiple networks or network equipment segment, it will be different networks or network segments of data information between a "translation" to enable them to each other, "understand" each other's data, so as to constitute a larger network. Wireless Router: Router (Router), is connected to the Internet in each LAN, WAN equipment, it will automatically select and set the channel routing according to the situation to the best path, according to the order to send signals back and forth. Router is the hub of the Internet, "traffic police." Currently the router has been widely used in various industries, various grades of products have become the backbone to achieve a variety of internal connections, the main force of the backbone network interconnection and interoperability with the Internet backbone business. The main difference is that the route between the switch and the switch occurs in the second layer of the OSI reference model (data link layer), which occurs in the third layer routing Wuhu router, i.e., the network layer. This difference determines the routing and switching information in the process of moving in the need to use different control information, so that the way to achieve both of respective functions are different. Router (Router), also known as the gateway device (Gateway) is connected to a plurality of separate logical networks on Wuhu partners for wireless router, so-called logical network is representative of a single network or a subnet. When data is transferred from one subnet to another subnet, can be accomplished by routing function of the router. Therefore, the router has to determine the network address and select IP path function, it can interconnect in a multi-network environment, the establishment of a flexible connection, data packets can be used completely different and the media access method to connect various subnets, routers only accept the source station or Additional information about the router, is a network layer Internet device.
