After installing a wireless network, you may find that the network does not support your applications as well. Users may complain about unstable connections and poor performance, which will impede application use. As an administrator, You need to diagnose the fault. First, find the root cause of the problem. The following table may give you some guidance. You may wish to see this table when you encounter a

Radio/TV network is not waiting for FTTH construction (1) In the context of "triple play", competition from telecom operators is becoming increasingly fierce. In particular, its export advantages and broadband acceleration have attracted a large number of users, the business of radio and television operators has reached the bottleneck stage. At the same time, us

We can use the network protocol analyzer to observe the network protocol analysis. Here we will explain the network analyzer. The best way to analyze data packets transmitted over the network depends largely on the device you have. in the early stages of network technology d

1: Preface:We are in the process of Android development, many of the implementation is to the remote server to take data, but not necessarily the current device must be connected to the network Ah, so at this time we are to make judgments,If there is a network, then go to the remote server to get data, if there

APIs and various message protocols, including some standards, allow users to build today's Software Defined Network (SDN ). However, the key issue is that not all people can achieve the same network, or they can achieve it in the same way. So,OpenFlowCan we lead all of us to the SDN Park in the same way? OpenFlow is an

The first step: should check the wireless network card driver is installed correctly. Right-click on "My Computer"-Properties-hardware-Device Manager to see if there are any network devices marked with a question mark or exclamation point, and if so, the wireless NIC driver is not installed correctly. Using the "Hardwa

The firewall consists of 4 parts of service access policy, verification tool, packet filtering and application gateway, which is a software or hardware between the computer and the network to which it is connected (in which the hardware firewall is rarely used only by the Ministry of Defense, because it

I believe many Win7 system users have heard of network drives, and when we turn on the computer, we can see the "Map Network Drive" option on the toolbar, so what is mapped network drive? A network drive, as its name suggests, is

identical, so if we fail to change the password of the wireless node device in the Local Wireless LAN in time, then some illegal attackers may easily use the default user name and password to access the local wireless node device, so as to have all the management permissions of the Local Wireless LAN. Later, sometimes we encounter the embarrassing situation that we cannot log on to the local wireless LAN. To restrict unauthorized users from using a local wireless node device, we must remember t

of radio towers, welding machines, trams or high-voltage power transformers, such as signal interference sources, can enable users to receive clutter (copper clad steel wire shielding weak, strong reception capacity), the user line caused strong interference. The jamming signal is often the unshielded part of the wire entry, because the relay cable has a shielding layer, interference and impact are very small. If the interference in a large place wit

In the previous article, we introduced some important points to pay attention to when purchasing Wireless AP. When purchasing wireless network cards, you must pay attention to some aspects. The following sections will list four points for your reference. We hope that this article will allow you to avoid detours when choosing a wireless network card. In addition to Wireless AP or wireless router, you must al

Some Android applications have two connection modes: "network" and "Network disconnection". "Network disconnection" and "Network disconnection" have two different interfaces, network disconnection API is called when the

Network resource Management network resources refers to the use of network equipment through a variety of means of installation, deployment, maintenance of the form of information containers or channels. The main difference between it and network equipment is:

Prevention methods: Modify the routing password, use a good network cable, reduce the barriers between the routing and Computer block, reduce the metal reflection! Other wireless signal interference, such as interference in the same frequency band. In the route to modify, the default is the band 6, multiple wireless signals, changed to other, not as well as others OK. Do not let others move your route, or
