I want to connect to a password-secured wireless network. I can connect to unsecured networks no problem.
I'm running Ubuntu Hardy 8.10 on a lenovo Thinkpad R91i.
In the notification area, it detects many wireless networks and shows that it has connected to the one I want (80-100% signal). I get no more prompts for the password after I enter it the first time. I've tried unchecking Wired under Network and both enable Roaming and specified the network I want to use under Wireless.
When I ping, though, I get no connection. I've pasted some details below. Fir iwconfig, I tried the s: prefix, which returned the command line but still didn't get me connected. The man page reads "Passphrase is currently not supported" so does that mean iwconfig is no help?
Please understand I'm relatively new and need some English thrown in to explain the commands. Thank you all!
