If the product is good, it will cause problems. It is not a problem inside the device itself. It will be worn out with long-term use. What if the wireless AP is faulty in use? This article summarizes the following 9 more common problems to help you solve the wireless AP failure problem.
Generally, the wireless AP can automatically adjust the transmission rate to adapt to changes in the wireless signal strength and ensure the smoothness of the wireless network. If the network speed is very low for a period of time, it indicates that the network has failed, and there are several possibilities:
1. The wireless network card of the computer turns on the power saving mode. When this mode is enabled, the transmit power of the wireless network card will be greatly reduced, resulting in a weakening of the wireless signal, thereby affecting the transmission rate of the wireless network.
2. There are obstructions near the AP. Look at the obstacle between the AP and the computer or between the mobile terminal. For example, if the AP is placed in one room and the Internet is in another room, the wireless signal may become weak due to the wall penetration, which may affect the wireless rate. .
3. A lot of terminal devices are connected. Log in to the AP's management interface to see if too many devices are connected, causing the rate to drop.
Second, the wireless bridge can not receive dataSince the data cannot be received, it indicates that the connection to the network is not properly established, and the cause of the failure may occur in the connection between the wireless AP and the switch. It is recommended to use a crossover cable to connect the wireless AP to the switch to test whether the fault is resolved.
Third, connected too many devicesIf the wireless AP is connected to too many terminal devices, the network speed will drop significantly. From the practical experience, once a single-frequency AP is connected to more than 20 people, it may be awkward. If you expect to use more people, it is recommended to add a wireless AP or use a larger AP.
Fourth, the wireless AP location is not correct, resulting in no Internet accessIf the company's office building is 6 floors, two wireless APs are used, which are on the first and third floors respectively. Measures can be taken to place two wireless APs on the second and fourth floors to achieve wireless coverage of the entire office building. Two APs are connected to the switch through a wired network and then connected to the Internet through a broadband router.
It may be caused by multiple signals of the wireless bridge. It is almost impossible to completely eliminate the multi-channel signal, and only reduce the multi-path phenomenon as much as possible. Try not to place metal objects near the access point or wireless client.
Sixth, the computer cannot communicate with the wireless networkIf the wireless network card shows normal operation, but the data is received and sent as 0, you can take the following methods:
1. Check all cables of the wireless AP and make sure the power indicator is normal.
2. Verify that all wireless network property settings are correct.
3. Make sure the computer receives a good signal from the access point.
Seven, wireless network transmission rate is unstableIf the wireless network is installed, the network communication is basically normal, but the data transmission speed is fast and slow. This is because the wireless devices are closely related to the environment such as distance and interference. They can automatically adjust the speed according to the environment, so the speed change is normal. The simplest, the distance is far, the transmission speed will be reduced. Generally, the wireless access device AP can be placed in the center of the wireless local area network device group, so that all wireless terminals are not too far away.
Eight, wireless network card display only sent without receivingIf the wireless AP is set up correctly, other people in the office can receive it via wireless, and the computer can access the Internet through the wired network, but the data reception through the wireless network is always 0. Check the wireless network properties and find that the IP address and subnet mask are not normal values. This indicates that the network card is not connected to the wireless network and does not obtain IP address information from the wireless AP. The cause of the failure is related to the wireless network settings. Different wireless networks use different SSID and WEP encryption. Therefore, the problem may be due to modifications to the network settings. The solution is to refresh and set up the wireless AP and modify the WEP encryption.
Nine, low communication rate between wireless APsThe farthest distance of the wireless AP bridge is about 150m. When two APs are at this distance, the connection failure failure often occurs. It can usually be solved by setting up an external gain antenna, but the cost is higher. Another method is to mount two wireless APs to an outdoor wall, using two walls as reflectors to enhance the front radiated waves. The protection of the basin-shaped container with the aluminum-plastic panel between the wireless AP and the wall surface is both beautiful and solves the problem of waterproofing and sun-proofing, and also plays a good reflection role. The connection rate after processing is significantly improved, and there will be no more dropped lines.

FLASH Memory vendors:1MB = 1000KB,1G = 1000MB
Operating system using binary arithmetic:1MB = 1024KB,1GB = 1024MB;
so there are some differences between display capacity and nominal capacity of flash memory product
Warm Tips:
How to verify the Capacity and Speed of the memory card?
1). Please use quality USB 3.0 card reader to verify all memory card by H2testw on PC. Real memory card should pass H2testw with no error.
2). Please don't use cheap card reader to test Micro SD memory card, speed of Micro SD memory card will be reduced by low quality card reader.
3). Micro SD memory card speed is greatly affected by card reader and the capacity you choose , USB port ect. Low quality device will 100% slow down card speed,1MB=1000KB.
