I have Fedora 9 installed on a laptop with a Dlin DWL650 PC card.

If I turn off all encryption on my wireless access point, it connects perfectly right out of the box (without ndiswrapper).

I normally use WPA-Personal with TKIP and a passphrase.

I am struggling get the working.

1) Do I allow the device to be controlled my network manager?
2) what should my /etc/wpa_supplicant/wpa_supplicant.conf file look like?
3) Is there some order of events that needs to be observed?
4) Do I fill anything in the KEY field in the wireless tab of the Network Configuration tool?

Again, adapter was recognized fine and works unencrypted.

I am just not knowledgable of the wpa_supplicant stuff.

Thanks.

also see the section on configuration near the bottom of that page, plus this page:

http://hostap.epitest.fi/gitweb/gitw...upplicant.conf

That is generic wpa_supplicant information; I have no idea how wpa_supplicant is integrated with RH.

[edit] The WPA-PSK/TKIP specific example:
http://hostap.epitest.fi/gitweb/gitw...-psk-tkip.conf

Of course you don't really want to have:

psk="secret passphrase" - that's just begging for trouble. Instead,
you want to create an obfuscated key:

wpapassphrase "My EsSiD" "My secret passphrase"

That will print out a stanza which you can just plug into the wpa_supplicant configuration file. Personally I just copy and paste the obfuscated key (the line with a very long string) and ignore the rest of the stanza.

For RH-specific stuff, have a look near the bottom of this page ("Startting wpa_supplicant"):
