Unstable WiFi connection
If the wireless connection disconnects and reconnects regularly, it may be:
case 1
- A problem due to power: In this case, one must give the access point as accessible as possible by removing the 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 orient the antennas.
case 2
- The proximity of other wireless networks: Many wireless networks side by side creating disturbances. It is advisable to change the broadcast channel default access point to minimize interference. Remember also to change the network name (SSID) by default!
case 3
- 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"
case 4
- The frequency is inappropriate: Some brands of WiFi receivers have preferences on the channel used by the WiFi access point. Thus, even 2 or 3 meters of 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 also marks Dlink, Netgear, Linksys ...
case 5
- 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), 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 telephone line quality.
case 6
- 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.
case 7
- A network protocol unstable: Some network protocols (Aegis, for example) are relatively unstable in a WiFi connection and can cause loss of connections. 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.
case 8
- The proximity of a camera :wireless cameras use wireless frequencies from 2.4 to 2.4Ghz-the entire spectrum used by WiFi, so as DECT phones, such a system may interfere with WiFi connection.
