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. V-Link Router: Introduction --- Anti-speed router using the router's user, many will find that their network down the line speed is limited, and how it was used as the routing function of the speed limit, of course, there may be those ill-intentioned The guy used the speed limit software, limit your network speed. How to lift the speed limit to control it? If someone opens the routing function of the speed limit, you can adjust the speed routers themselves, of course, if you do not know the way by setting up a wireless network router password, you can reset the router, and then re-set the best average based on the number of users distribution, lest we trouble not happy. The second case, they are being used to limit the speed of the software, you can use anti-speed software. As an internal network router external interface device, the attacker into the internal network of the first goal. If the router does not provide attack detection and prevention, it is also a bridge between the attacker entered the internal network. On the router to provide attack detection can prevent some attacks. Wireless Router: Many users will surely have this question, there is no Wi-Fi radiation it? The answer of course is yes, but we can rest assured that the output power of wireless LAN equipment is generally below about 100mW, let's do a comparison: We are using the phone call or send text messages when the output power range of 600mW, and handheld walkie-talkie likely to 5W. Wireless LAN equipment is lower than the output power of the two products are many models of routers and wireless LANs do not like the phone or walkie-talkie as close to human use, there are too many scruples unnecessary use. There's friends always complain that their products transmission range is too small, the family are dead signal, or often unstable, dropped more. If there is no interference, then, a few hundred meters is not a problem. But even at home, too many obstacles, glass, walls and so on. In fact, the strongest metal router is blocking the signal characteristics of the load-bearing walls in your home if the metal more, then the signal is weak in many wall is normal. But usually, about 100 square meters of the house, a router is enough. Set up wireless LANs are a lot of friends who complain that their home wireless router signal coverage is too small, the family has a signal dead or network instability, frequent dropped calls and so on. In fact, the current commonly used household 54M wireless router signal coverage throughout the average home is sufficient. But since when in actual use, the signal will be some objective factors, such as the emergence of environmental decay, which can not be avoided. Barriers to home too, glass, walls, etc. will cause the radio signal attenuation. In fact, blocking the signal is strongest metal, if your home is more than the metal bearing wall, the wall so many weak signal is normal. But usually, about 100 square meters of the house, a router is enough. Router model _ Anhui Technology (certified) _ router provided by the Technology Development Co., Ltd., Hefei, Anhui.
