The reason why the signal of wireless network equipment is suddenly strong and weak

In the process of using a wireless network, wireless network signal instability, suddenly strong and weak is the problem that we often encounter, resulting in wireless network signal instability factors than more, of which wireless devices are not involved, the following we from the wireless network equipment perspective, to help you find wireless network signal instability of the "real killer."

The location of wireless equipment is unreasonable

Generally speaking, wireless routers should be placed in the middle of the entire room, regardless of the signal coverage or transmission speed can get the best results. In addition to our room there will be many wall corners, each corner will affect the transmission of wireless signals, so in the design of wireless networks and equipment placement should try to avoid corners.

Second, the wireless router itself is not stable

When the wireless network signal instability and wireless router placement is not a problem, we should first consider the problem of the wireless router itself.

In this case we can close the laptop to the wireless router, or the wireless router to the PC plugged into the wireless network nearby, reduce the distance to see the stability of the wireless signal. If the connection speed and signal strength is still not ideal, you need to start checking the stability of the wireless router. The most common approach is to download the latest patches or firmware drivers from the official homepage of the wireless product manufacturer.

The upgrade driver method is particularly effective for wireless router signals that are not stable or are automatically dropped by wireless cards at intervals of several minutes.

Third, the wireless network card itself is not stable

Carpet Search is often the most able to find problems, although it looks a bit stupid, after the wireless router, the receiver of the wireless card has become a key suspect object. From the wireless card point of view, the problem is generally due to the following two points:

1, the wireless network card itself drive problem, must use the drive on the disc to install the wireless network card, because the driver is correct or not and whether the official version of the driver is the main factor to determine the stability of the wireless network.

2, the wireless network card itself connection speed, it is well-known in the network when two computers in the net transmission data, if a computer's network card is set to single or transmission speed of 10M, while the other computer network card is duplex or transmission speed is 100M, At this point, there will be two network cards frequently negotiate connection speed and working mode and not normal transmission or frequent disconnect. Wireless network card is also so, it is recommended that you choose wireless router and wireless network card products should try to choose ancillary products.

Iv. DHCP data packets cause instability

Experienced users know that DHCP services can help us automatically allocate the IP addresses of computers in the network, but in actual use DHCP can cause network instability, such as the lease to get IP again but found that other computers in the network are already using the IP address, Or the DHCP information is frequently negotiated between the computer and the wireless router.

In fact, these DHCP packets can not be completely, for the average home users, the network is not a large number of computers, we can manually set the IP address and other network parameters to reduce the DHCP packet.
