Wireless Router: If the antenna is really the most important words on today's wireless router market competition is not the product's performance, and turned into a struggle antennas. Wireless through the wall in the end how to judge, when users select the radio What factors should reference? Author on this issue with the relevant experts in some discussions today to tell you about many days of learning outcomes. Antenna is an important component of wireless products transmit and receive wireless signals, is the basic guarantee wireless communications. Whether it is a signal transmission or signal reception, RF signals are transmitted from the antenna in the form of electromagnetic waves in the form of radiation. Then join the city wifi is not an option wireless product, it can be used as a wireless antenna gain performance of the most critical determinant indicators? It is not the case. V-Link Router: control software router is a router plays a key feature. From a software installation, parameter is automatically set to the software upgrade is essential. Software installation, parameter setting and debugging more convenient, more easily grasp the user, can be better used. With the increasing application of computer networks, existing network size may not meet the actual needs, will have to expand the network size requirements, so scalability is a network in the design and construction process must be considered. Size mainly depends on the number of expansion capability expansion slot router supports or expand the number of ports. With the construction of the network, the network will become increasingly large-scale, network maintenance and management, the harder it were, so the network management is very important. In our installation, commissioning, repair and maintenance or expansion of computer networks in the process, inevitably give the network changes in equipment, that may want to plug the network components. The router can support hot plug, it is an important performance indicator of the router. V-Link router: router as a network device in the "black box" city wifi signal, working in the background. When the user selects the router, more from the technical point of view, such as scalability, routing protocol interoperability, wide-area data services support, internal ATM support, SAN integration capability. In addition, select router should follow the following basic principles: the principle of standardization, technical simplicity principle, the principle of environmental adaptability, manageability, and fault-tolerant redundancy principle principle. For high-end router city wifi, more should also consider whether and how to adapt to the network backbone performance requirements of high reliability, high scalability, and the interface routing lookup and data forwarding. High reliability, scalability and performance of the "three high" characteristics are different from the high-end routers and low-end router key. MAC address is the MAC address of the router in the LAN, this value can not be changed. IP address is the IP address of the router in the LAN, LAN default gateway for all the computers must be set to the IP address. Note that if you change the LAN port IP address, you must log in to this router WEB management interface with a new IP address to. And if the new LAN port IP address you set with the original LAN port IP address is not the same segment, then city wifi investment, virtual server and DMZ host function of the router will fail. If you want to enable these features, to re-set it. The subnet mask is the subnet mask of the router in the LAN, usually 255.255.255.0, and all the computers in the LAN subnet mask must be set the same here. Select "WAN port settings" appears below the setting screen, mainly on the means of access and permission settings.
