Use dongle to optimize mysql as followsThen run the following program and report an error.$ Cn = mysql_connect ('localhost', 'username', 'password') or die (mysql_error ());If ($ cn){Echo 'success ';}Else{Echo 'FA ';}?>The result isCan't connect to MySQL server on 'localhost' (10061)As a result, I checked the service to see if it was started. As shown in the figure below, we only need to click start.

With the advent of the 3G communication era, it has also brought a variety of multimedia applications. In recent years, the rapid development of high-speed WLAN, which can provide close data rates, has gradually become an important application for the combination of 3G and WLAN, and has a deep potential for market development. In the 3GPP and other mobile communication standardization organizations, the con

Content Summary: First compares the WLAN and the GPRS two kinds of technology characteristic, then proposed a mobile IP support WLAN/GPRS network seamless roaming fusion scheme. It uses WLAN network and GPRS network in the technical complementarity, can quickly provide users with the support of seamless roaming data services. This scheme is based on the following

After developing the mobility and application plan, IT staff should also clarify the following important issues to the WLAN supplier during WLAN evaluation: 1. What features does the supplier provide in its WLAN solution? Currently, WLAN products can be divided into two categories-controller-based and non-controller-ba

Wireless LAN (WLAN) has the advantages of convenient installation, good mobility, flexible use, and easy expansion. However, many new problems have emerged in the planning, design, testing, and security management of WLAN. 1. Features of Wireless LAN The MAC protocol of WLAN is different from that of Ethernet. The transmission protocol of Ethernet is CSMA/CD ), t

We should have some knowledge about all aspects of wireless WLAN. The standards for wireless WLAN testing may be unclear to everyone. This article will list five steps for you to test the wireless WLAN. Wireless WLAN Test 1. Channel Test Different from wiring tests, signal strength, noise intensity, and signal-to-noise

No one is skeptical that WLAN is currently the most popular technology and market in the network industry. However, the monitoring and testing of WLAN is still a problem that is often ignored, people are even using laptops and wireless NICs to test and accept wireless projects. This reminds us of the early Ethernet testing scenarios. The following is a discussion of the basic concepts of wireless testing. I

We can basically consider solving the security problems of WLAN from the following aspects. 1. First identify the security strategy, locate the main use of WLAN throughout the work, involving the transfer of data and personnel, equipment. Then, the physical location of AP, the access rights and control mode of the client are planned. 2. Start with the network structure. Limit the range of

After the emergence of WLAN technology, "security" has always been a shadow around the word "wireless". Attacks and cracking against security authentication and encryption protocols involved in wireless network technology have emerged. Currently, there may be hundreds or even thousands of articles on how to attack and crack WEP on the Internet, but how many people can truly break WEP's encryption algorithm? Next I will introduce some knowledge about W

WLAN switches are quite common. So I studied the functions of WLAN switches and how to quickly implement the networking scheme. I would like to share with you here, hoping to help you. A wlan switch can connect to a WLAN Access Point (AP) through a wired connection (with a switch port ). They can also connect to the en

Few users may be familiar with WLAN switches. If you are interested, you can first understand the WLAN Network Architecture and access point functions, and then further understand the features and practical applications of WLAN switches. A wlan switch can connect to a WLAN A

Laptops, smartphones and tablets are mobile devices that each university can choose from. In order to meet the need for Internet access anytime, and to cope with more bandwidth-intensive mobile applications, colleges and universities have started investing in their wireless LANs so that students and faculty can transmit larger files and applications over wireless networks. So today's WLAN can be connected to a wired network through a variety of ports

I. BACKGROUND Because of the current commercial situation in Japan and the 3G test conducted in Europe did not achieve the expected results, 3g-foma operators 3G plans are further postponed , the company has also been WLAN (Wireless LAN) and 2.5G GPRS integration on the agenda, in order to strengthen the broadband and applicability of wireless Internet access, to fill the 3G delay brought about by some of the market and technology space; Meanwhile, t

Netsh literally refers to the network shell. In fact, it is a command line utility that first appeared in the Windows 2000 operating system and can help manage network settings in WINDOWS. Since then, Microsoft has continuously improved it and added some new command sets to it. For example, a set of WLAN commands are added to Vista and Server 2008 to manage 802.11 wireless connections and security settings. Now, another

In recent years, SoftSwitch technology has become the focus of public attention, it will become the core technology of the next Generation network, the information industry after a turn to put forward to the next generation of IP Fusion network SoftSwitch technology, is currently active in 3G core network technology research, the ultimate goal is to have the integration of multimedia business capabilities of the full IP network. In this regard, 3GPP has played a significant role, this paper put

With the improvement of the Wi-Fi standard, the size of 802.11 chips is decreasing, and the functions are expanding, the feasibility of the VoWLAN telephone system is also gradually improved. Dual-band mobile phones can use WLAN connections to provide reliable in-house voice services, while broadband telephone services connect notebooks through WLAN. On the other hand, the network phone number based on

Rivers and Lakes !!The wireless secret that everyone is competing for-the unique nine swords are coming to the fore !!Those who win this book can win the world!L details:1. Adjust the channelApplication description:Because only some countries have opened 12 ~ 14 channels, so in general, use 1, 6, 11 channels.You can adjust the transmit power of a wireless device to avoid this situation. However, in a three-dimensional plane, it is difficult to achieve zero co-frequency interference in any region

Many of us do not know much about wireless network devices. How does a wireless switch work? This article provides detailed answers to this question. WLAN switching technology centrally controls access points and wireless switching functions, which is very similar to smart switching technology in the Wired World. This technology provides the structured blueprint and centralized troubleshooting capabilities required to extend

SOX, FIPS, and HIPAA. If you are using WLAN technology and are not familiar with these terms, please listen. With the emergence of problems such as land security, enterprise scandal, and dissemination of medical information on the Internet, the management department has passed many regulations that require strict attention to the security of the IT field. SOX, FIPS, and HIPAA are abbreviated as Sarbanes-Oxley, federal information processing standards,

Step 1. Turn on wireless 1. Before the WLAN network we have to open the WLAN connection function, we click on the mobile status bar down, and then we will open the notification bar, where we put the WLAN click Green is opened, the specific operation such as. 1. We return to the mobile desktop after the use of the next status bar.2. Then open the status bar with
