That networks wireless security is disabled or a password has not been set That's usually the case in a public place (coffee shop).

Yes, it is. WEP is one form of security for a wireless network, the key is required to decrypt it.
It is not required, no.
This is illegal and you shouldn't try. If you own the wireless network, it should be provided by the network service providers!
You can't. If you do not know it and there is no other computers connected to the same router, there is no way you can get the key without setting up a new one.
Secured wireless networks are networks with, usually, a WAP key. A WAP key is located on the actual modem and/or wireless device, etc. Some setups may allow the creator of the network to establish a password in replacement of a standard WAP key.

Wireless routers are required to have a wireless network connection. The stronger the wireless signal the further the signal will reach. Although the network can be seen by others within it's signal range, for security reasons your network cannot be accessed without a network key. Specifically a N rated wireless router has a powerful signal. G routers are much less powerful. For any router to work you need to connect a wireless receiver to the computer you want on the network.
Protected wireless networks have a key to gain access to it. If your key does not match the key which is set in the router's settings, you get network security key mismatch error.
encryption key
WPA-PSK2 AES with a long key.
The WEP key is the password for the wireless network. If you generate the key in dessid, when you try to join the network you can tap in the password box and select "Paste." Then the key will be pasted in and you can join the network.
