Hi,

Iwspy is used to set a list of addresses to monitor in a wireless network interface and to read back quality of link information for each of those. This information is the same as the one available in /proc/net/wireless : quality of the link, signal strength and noise level.This information is updated each time a new packet is received, so each address of the list adds some overhead in the driver.

Follow these steps carefully:

1. If you are on an open wireless network then it is possible that Ubuntu will automatically locate the network and connect to it. This is because Ubuntu is configured by default with roaming mode enabled. In roaming mode the networking system searches the airwaves for wireless networks it can connect to. If it finds either an open network, or one for which it has the encryption key it will automatically connect. A status indicator in the top right hand corner of the desktop indicates whether or not a network connection is active. The indicator icon shows two computer monitors. If the icon shows a red warning triangle with a white exclamation mark then there is currently no active connection.
   
2. Clicking with the left-hand mouse button on the network connection status icon will cause a drop down menu to appear.
   
3. Ubuntu will locate a wireless network called neilandcheryl and shows moderately low signal strength. The small shield icon next to the network name indicates that this is an encrypted network. It is also possible from this drop down menu to connect to other wireless networks, configure a network connection manually or create a new wireless network.
   
4. If the above drop down menu lists a wireless network for which you have an encryption key or passphrase simply click on the network name to invoke the Wireless Network Key Required dialog
   
5. Select the key type (Passphrase, WEP Hex or WEP ASCII) and the authentication type (Shared key). Having made appropriate selections enter the key or passphrase you configured when you set up your wireless base station and click on the Login to Network button. After a short wait the network connection should be activated. If the connection fails go back and check that you entered the correct settings for the encryption key or passphrase or try using the Network Settings Dialog described below.
   
6. A more advanced network configuration tool is accessible by selecting the System menu at the top of the desktop, choosing Administration and the clicking on Network. The Network Settings dialog lists wired, wireless and modem connections. If no Wireless Connection is shown in the list, check that you have a wireless adaptor card installed into your system. Assuming you have a wireless adaptor installed your Network Settings dialog should appear as follows:
   
7. To configure a wireless network connection, select the Wireless connection entry from the Network Settings list and click on the Properties button. The following dialog will then appear:
   
8. If the Enable roaming mode toggle is set, uncheck it to gain access to the configuration fields below.
   
9. Select the appropriate Network name (ESSID) from the drop down list. If no networks are listed it may be that you are not in range of a wireless network. After choosing a wireless network, select the password type and enter the authentication key required for access to the chosen wireless network.
   
10. If your wireless base station is configured to provide IP addresses using DHCP (the most common configuration) then leave this setting unchanged. In the unlikely event that you are required to manually enter network configuration information change this setting to Static IP address and enter your IP address, subnet mask and gateway address. If you are unsure as to what these values are check with your network administrator.
    
11. All being well your Ubuntu Linux system should now be connected to your wireless network.
