WLAN disconnection and reconnection

[Spy$Eyes]

If the wireless connection disconnects and reconnects regularly, it may be one of the following problems:

1. ADSL Problem

Most of the time, WiFi is not necessarily involved, it may be a problem connecting ADSL :

• Disconnect ADSL - The disconnection may be related to telephone wiring or a poor quality connection. This is particularly the case when using telephone extensions. Moreover, historically, many phone lines are equipped with a condenser. This disrupts the use of the telephone line with ADSL, so it may be useful to determine if the line has such a capacitor and if necessary remove.
• Blocker ADSL Disconnections - The right theoretical speed is calculated by entering the line number in software. The result is instantaneous. However, there is a margin of safety too important in the interpretation of measurement results. Thus, in some cases distance limits between the home and the server, the software maintains a right to ADSL distorted. Warped as saying a speed too high in relation to reality. By calling the hotline, ask a technician measures the ability of the actual ADSL line. He will inform you that you probably can not hope to 8 Mbit / s (for example) but only 2 Mbit/s.
• ADSL synchronization problem: the causes - To transport the data through your telephone line, ADSL uses higher frequencies between your modem router and the NRA (central ADSL in your area).

2. Problem transmitting power

In which case, we must make the access point as accessible as possible by removing nearby objects. It should also be aware that the bearing walls or concrete slabs greatly weaken the signal. If it is a MIMO access point, be sure to orient the antennas.

3. Proximity to other wireless networks

Several wireless networks side by side creating disturbances. It is advisable to change the transmission channel default access point to limit interference. Also remember to change the network name ( SSID ) by default!!

4. Problem standby card WiFi

In the properties of the network connection (WiFi), click the Advanced tab, then uncheck "Allow the system to turn off this device".

5. Frequency distribution of non-adapted

Some brands of wireless receivers have preferences on the channel used by the WiFi access point. Thus, even 2 or 3 meters from the modem, some brands will have an unstable connection. On the whole, we can then test a few channels 5, 6, 7, 10, 11 or 12. The centrinos (or more generally integrated receivers laptops lately) work better on high channels: 10 or 11. This is the case also marks Dlink, Netgear, Linksys ...

6. Interference due to a DECT

Wireless phones (DECT) use the frequency band 1800-1900 MHz while WiFi uses the 2.4 GHz band and two bands in 5 GHz. However, with equipment of poor quality, there may be interference (same problem with microwave ovens can interfere with WiFi waves). If your DECT base is located near the modem (less than a meter), two transmitters can then disrupt them. Result: WLAN disconnects and a parasite in your phone line. It may suffice to remove, so the DECT base to get a WiFi connection and a permanent telephone line quality.

7. Using a USB extension cable

With the dongle key ( USB ) WiFi, many manufacturers supply a USB extension cable to connect the key. This extension may create interference in some cases, you can take the test without the extension.

8. Protocol unstable network

Some network protocols (eg Aegis) are relatively unstable in a WiFi connection and can cause loss of connections. Just then uninstall. To do this, go into the properties of the wireless connection, select the corresponding line in the general tab, then click on uninstall below.

9. Proximity to a wireless camera

The cameras use wireless frequencies from 2.4 to 2.4Ghz, which represents all spectrum used by WiFi, so, like cordless phones, this type of system can interfere with a WiFi connection.
