In the use of wireless LAN, if the network signal is not good, it is likely to cause interference caused by a number of reasons. The general causes of interference are the following points.
1. Nearby Equipment disturbances
Wireless LAN using the ISM wireless band, the use of 2.4GHz operating frequency, and some household appliances, such as the frequency of work, such as microwave ovens, cordless telephones and so on. Therefore, when using wi

implement "sticky session" or simply avoid session and other state management techniques that save user state on a separate Web server.
If you do not use session, turn them off; You can turn off the session functionality of your application through Internet Service Manager (see ISM documentation). If you decide to use session, there are some ways to minimize their impact on performance. You can move content that does not need a session, such as a Hel
IIS 5.0, which are implemented in ASP. If you want to use custom (or modified) Help files, error-handling pages, you must create the directory yourself on the IIS 6.0 Web site.
Further analysis of the sub-component manifest for IIS 6.0 shows that Internet Service Manager (ISM), which was previously installed by default in IIS 5.0 and IIS 4.0, is gone. However, if you click on "World Wide Web Services" (one of the subcomponents of IIS 6.0, however, f
building a Web server, the system has established a default Web site and provides content services such as IIS Help for the system itself. However, if you can provide different services according to different needs, the creation of multiple Web sites is an ideal choice, such as creating an ASP program site to run the ASP program.
First create a physical directory on your hard disk that holds the Aspbbs program, such as D:\aspbbs.
Select Internet Server Manager to open

From the application requirements, the wireless network is very suitable for schools of some sites that are not easy to network wiring applications. Now most of the campus has wired LAN, how to further expand the original network, so that every corner of the campus in the network, the formation of a true sense of the campus network? This article is to introduce how to use Wireless LAN technology to form a campus network.

Compared with other systems working in the same band, Bluetooth is faster and has shorter packets, which makes Bluetoot

Many people must have such confusion: everyone is familiar with the 2G/3G/4G communication standard, 5 G what, how to go with the WiFi pull on the relationship. The previous article explains that traditional WiFi is susceptible to interference and there are two reasons:
