access points around, or noise generated by other interfering devices such as microwaves and cordless phones. Monitor the access point that the client is attempting to connect to, and pay close attention to the step in which the connection fails--association, authentication, or authorization. Summarize We list 10 problems that technicians are likely to encounter in the current network. In most cases, you can position the problem on one or more thin

not ideal. Solution: If operators can increase input, can increase the number of AP and increase the total bandwidth in the user-intensive area. And for those who need wireless connection can also purchase the wireless AP, through the bedroom network plug into the campus network use, thereby reducing the operator to provide access points and insufficient bandwidth problems. 3.3.2 signal when good and bad, internet speed is not stable Failure Description: According to the single teachers dorm

, so that priority programs can meet the required bandwidth. Six. Enhance wireless security Even if the router set the password, it is easy to crack. It's easy to figure out who's stealing your Wi-Fi, but the best way to do that is to enhance the security function and block them completely. Using the WPA password is required, but this combination is easy to crack, so it is recommended to learn more about maintaining network security skills. Seven. Closure of other disturbed equipm

Nowadays, wireless router is a necessary artifact of network connection in every household. With wireless routers, mobile phones, computers, tablets and other intelligent devices can easily access the Internet. However, even if it is so convenient, there will inevitably be some problems. Not only the signal is not stable, often not open the situation of the Web page, and even frequent drop lines are commonplace. So, the network signal is poor, WiFi frequent drop line, excluding network fault, w

section. 6, interference from a cordless phone, microwave oven, or a nearby high-power network interrupts your network and tries to use a different channel. 7, when you connect too many client devices, or when someone uploads or downloads a large amount of data, the WiFi connection slows down. When you notice that the Internet is suddenly slowing down, you should go to the web and check it out to see if someone is watching the video or doing some

settings, the home wireless channels to manually modify it, experts suggest you can try more than a few times until the best channel value found. It is recommended that you use WiFi Stumbler or wifi Analyzer software to find the best channel for your monastic router. 3. Reduce interference from other wireless devices Apart from the wireless signals in the neighborhood, other wireless devices in your home can also affect wifi efficiency, such as microwaves,

First, to consider the notebook this aspect of the problem, there may be due to the compatibility of wireless network cards or drive problems caused by network links error, we want to verify that the wireless network card itself has no quality defects, and then check the driver of the network card is normal, or the driver version is too old. Because the wireless router transmits the signal through the electromagnetic wave, we must take the environmental problem into account when choosing the pl

Slow Internet access is almost the most frequent topic for each broadband operator to receive complaints from customers. Research has shown that most consumers currently use WiFi speed is generally only about 50% of its router bandwidth limit. WiFi speed does not meet expectations, with these six factors. 　　1. WiFi Signal Congestion When a user accesses a network via WiFi, it is like listening to a radio station, using a fixed-frequency wireless band, so how much similar signal la

Troubleshoot problems with Wi-Fi wireless connection failure Wireless network fault Many more than one, there are many "incurable diseases." So this article mainly explores the reasons for the failure of Wi-Fi wireless connection. Through six aspects, for everyone to analyze the reasons and solutions. I hope this article will help you solve the problem. Wi-Fi wireless connection failure reason one radio interference Radios may come from a wide range of consumer electronics, such as

Internet access through the router, if the use of the environment, the ios/android system wireless terminals can not search the router signal, you may follow the following methods to troubleshoot: [IOS] Do not search for wireless signal When the wireless terminal is unable to search for a signal, verify that the wireless terminal's wireless switch is turned on. As shown in the following illustration: [Android] Do not search for wireless signal When a wireless terminal cannot search for a s

By analyzing the overall structure of the network, Google is able to determine which sites are rated as the best source of information for users who are most interested in their information. As the scale of the network grows, each new Web site will be another point of information, as well as another vote to be credited, and the technology will continue to improve. 5. You don't have to sit in front of your desktop to get the answers you need. The world is becoming mor

foreign manufacturers because of early development, product line is broad, so the technology leader, and local vendors to multi-functional product-oriented win.But it cannot be denied that the price war of local firms is a key factor in the threat to foreign businessmen. Due to the improvement of the process, 8-bit MCU and 4-bit MCU spreads booms, 8 has gradually become the mainstream of the market, the current 4-bit MCU is mostly used in calculators, automotive instruments, car anti-theft devi

card for the high demand situation. The load-bearing wall of reinforced concrete structure has a strong obstruction to the wireless signal. Therefore, the "duplex" structure of residential and Villa class home environment, the best signal coverage effect of the solution is to configure the wireless router for each layer. In practical applications, the coverage of indoor AP can only be up to 30 meters. 802.11b actual use rate is only about 40% of the nominal value, the conversion rate of data

These days a friend of the computer internet speed is very slow, look at the connection properties of the wireless network, found that the connection rate incredibly only 2Mbps, and sometimes only 1Mbps. The computers in the wireless LAN are in the same room, the previous connection rate is normal 11Mbps. This is a puzzle to my friend. The specific solution is as follows: Wireless network equipment can adjust the transmission rate intelligently to adapt to the change of wireless signal inten

performance of WLANs, such as cordless phones (2.4 or 5.xGHz), Bluetooth devices (2.4GHZ), pulse radar (5.4GHZ), microwave ovens (which will generate pulse interference in the 2.4GHz band), low energy RF light sources (2.4GHZ), and meet emerging " Full Band "required broadband 5GHz devices, from a 802.11 ap or wireless router to another 802.11 AP or wireless router caused by in-band interference and so on, you can pay attention to the erection or pla

entire wireless spectrum, and then provide you with the details of your home network already in channel usage. I was surprised to find that I was sharing Channel 1 with four other routers. This is not the ideal situation. Because Channel 9 was not used, I used this channel instead, which helped me significantly improve latency and throughput. 8. Use your router's 5GHZ network 2.4GHz frequency is very crowded, not only because the neighbor uses the same frequency, but also has the baby monito

Wi-Fi wireless network is also our more common network. So for this fault, let's briefly introduce one, that is, Wi-Fi wireless connection is not a problem. Wireless network fault Many more than one, there are many "incurable diseases." So this article is mainly about Wi-Fi wireless connection is not the reason. Through six aspects, for everyone to analyze the reasons and solutions. I hope this article will help you solve the problem. A radio disturbance Radios may come from a wide range of co
