People face many situations where their WiFi connection is unstable. This situation can arise if there is a problem with the network of the operator. The problem can also occur due to an unstable power source. The trouble can arise due to other related networks. A user can have similar problems if there is a disturbance with the Wi-Fi card. An inappropriate frequency of the operator can also put the connection in trouble. There can also be interference due to a cordless phone in the particular network. Many users using a USB extension cable can also experience the same trouble.
If the wireless connection disconnects and reconnects regularly, it may be:
A problem due to power: In this case, one must make the access point as accessible as possible by removing objects nearby. It should also be noted that the load-bearing walls or concrete slabs greatly weaken the signal. If it is a MIMO access point, be sure to orientate the antennas.
The proximity of other wireless networks: Many wireless networks side by side create disturbances. It is advisable to change the broadcast channel default access point to minimize interference. Remember to also change the network name (SSID) by default.
A problem of implementation of the WiFi card: In the properties of the network connection (WiFi), click the Advanced tab, then uncheck "Allow the system to turn off this device".
The frequency is inappropriate: Some brands of WiFi receivers have preferences on the channel used by the WiFi access point. Thus, even two or three meters away from the modem, some brands will have an unstable connection. As a whole, we can test some channels: 5, 6, 7, 10, 11 or 12. The centrinos (or more generally receivers integrated portable recent) work better on high channels: 10 or 11. This is the case for Dlink, Netgear, Linksys.
An interference related to a DECT cordless phone: DECT use the same frequency band as WiFi, around 2.4 GHz (same problem with microwave ovens can interfere with the WiFi waves). If your DECT base is located close to the modem (a meter away), two transmitters can then disrupt themselves. Result: WiFi disconnections and parasites in your phone line. Just move away the base of DECT to recover a stable WiFi connection and good telephone line quality.
You are using a USB extension cable: WiFi dongles (USB) manufacturers provide an extension cord to connect the USB key. This extension may create some interference, so you can take the test without the extension.
A network protocol unstable: Some network protocols (Aegis, for example) are relatively unstable in a WiFi connection and can cause loss of connection. Just uninstall. To do this, go to the properties of the wireless connection, select the corresponding line in the general tab, then click uninstall below.
The proximity of a camera: Wireless cameras use wireless frequencies of 2.4Ghz - the same spectrum used by WiFi, so as with DECT phones, such a system may interfere with WiFi connection.
