Wireless router frequent drop-off solution

　　1. Pay attention to placement

　　Reason: Although most manufacturers advertise their wireless router products effective transmission distance of indoor 100 meters, outdoor 400 meters. But in fact, these nominal distances are theoretical data. In practical applications, the wireless router's signal cannot transmit such a long distance at all. When the distance between the router and the network card is too far or too many obstacles between the two, wireless signal will be severely attenuated, thereby narrowing the coverage of the wireless signal caused by frequent drop of the phenomenon appeared.

Solution: Narrow the distance between the wireless router and the network card, minimize the obstacles between them, or use the external gain antenna, wireless network Extender to extend the coverage of wireless network signal.

　　2. Attention to interference sources

　　Reason: If there are interference sources near the wireless router, such as microwave ovens, mobile phones that can transmit or receive radio waves, Bluetooth devices, wireless speakers, etc., they will interfere with the normal use of wireless routers.

For example, some digital cordless phones use the 2.4GHz band, and wireless routers are usually in that band. If both devices use the same frequency of channels, then there will inevitably be interference with each other, triggering the failure of the line.

Workaround: Locate and remove these sources of interference. For the frequency of the channel overlap, you can change the frequency of the wireless router to eliminate conflicts.

　　3. Note Transmission rate

　　Reason: wireless routers with different wireless standards often have different transmission rates. For example, the highest rate of 802.11g+ can reach the 108mbps,802.11g maximum rate of 54Mbps.

The connection speed of the wireless router is different from that of the network card. For example, the use of the 802.11g+ standard wireless router, 3 meters in the range of no occlusion rate is likely to reach the theoretical value of 108Mbps, if increased connection distance, then the wireless router in order to maintain the stability of the connection, will automatically spin down as the distance increases, automatically transfer speed to 54Mbps or even lower.

Sometimes because of product design and connection distance and other reasons, some routers do not play the automatic spin down function in time or have been at two different rates of swing, which will produce a drop-line phenomenon.

Solution: The wireless router can enter the management interface, the wireless router to slow down manually, so that wireless transmission more stable and reliable.

　　Other Solutions

If you are not able to solve a variety of drop failures using the above methods, we may also consider using the following methods:

1. Update firmware. Generally the latest firmware will eliminate the bugs in the product, making the product more stable and reliable.

2. Whether the product is poor heat dissipation. When the product is out of heat, there is a phenomenon of unstable work. The wireless router can be cooled.

3. Attach importance to "extraneous factors". If the network has a computer infected with a virus or trojan, then a large number of useless packets will plug the network, resulting in a drop in the situation; too many DHCP servers in the network, causing confusion of IP address, will also cause the fall of the line. These and products are not related to the situation can not be ignored.
