I'm not sure what I'm doing wrong, I've installed Gnome network manager. It shows me Network Connection Properties (eth0 and eth1). I have eth0 configured as a wired connection, so I select eth1. I have 3 connections in the dialog box, Wireless Connection, Ethernet Connection and Modem Connection. When I click on Wireless Connection, it activates the Properties button. When I then click on the Properties button it has a check box next to Enable this connection and says 'Network Name (ESSID). I enter my network SSID here. Next it says Key type - Hexadecimal and the options are Plain ASCII or Hexadecimal. Since I don't know my key in hex, I chose ASCII. Next it says WEP Key. (I'm running WPA2-PSK) I enter my key here. Below this it says Connection Settings:
Configuration - DHCP (All of which I leave alone)
IP address
Subnet mask
Gateway address

Then I click OK.

It tries to activate the connection and it times out.

Any help would be appreciated.

Thanks.
