I have set the computer generated passcode as the passcode of my wireless network.but I have forgotten it.is there I can view the computer generated passcode?

Usually once wireless passcodes have been entered you can no longer view them unless you reset the router/modem to basic settings and get a new code. You computer may have stored it in some way depending on the program you used to generate the passcode but that would depend on the program used and most don't for security issues.

There would be other means to get it, some easy some hard depending on your wireless encryption (WEP, WPA-PSK, WPA2-AES), but those methods would not be open for discussion here.

Just reset your router! Get a new password! Remember this one though :)

If you remember your Routers Password, go to Wireless Security Settings and enter a new passcode.
They do have passphrase to WEP Converters, but have not found WEP to passphrase converters:
