I've seen posts revolving around this issue on many different forums but none really have given and answer to the problem that i've seen thus far. so I'm trying to connect to a wireless network with WPA/WPA2 encryption. Every time WICD gets to the point where it searches for a DHCP server but cannot aquire an IP address. This only happens if the network is encrypted though. If I take the encryption of the network I can connect no problem. Looking in the wicd.log file I find a few errors that I have searched for but cannot find any answers.

I'm kind of lost as to why I'm getting the no such file or directory outputs along with the PSK generation failure. Can someone please point me in the right direction!

I think there is no question that this has something to do with wpa_supplicant. That is the component that provides encryption. The only question is what exactly is the problem.

The 'no such file or directory' makes me wonder if wpa_supplicant exists. If it does exist then maybe there is another file that it needs and that is missing.

The first message above, stopping wpa_supplicant, makes me think that wpa_supplicant might exist. Therefore it may be missing some file on which it depends.

Sometimes a given wpa_supplicant binary only works on one specific chip set. Maybe you have the wrong build of wpa_supplicant.

Hello together,

I think stress junkie is right, it has to do with wpa_supplicant. Did you configure wpa_supplicant.conf?
As far as I know wicd is not able to connect to WPA2 encrypted networks without wpa_supplicant. Otherwise one does not need Wicd. So I'd suggest to disable wicd, check the wpa_supplicant.conf and try on the commandline as rootIf you have a Slackware full installation, the wpa_supplicant.conf should be there. You may post the errormessages if you tried wpa_supplicant on the commandline. If wpa_supplicant on the commandline connected to you accesspoint, you may use in order to get a lease.

If you don't get it, please provide more information about your hardware.

As long as wpa_supplicat is installed, wicd should connect to any wpa2 connection. No configuration needed except putting in the passphrase in wicd. I would try reinstalling the wpa_supplicant package and try again. I would also clear out /var/lib/wicd just to make sure.
