Ndiswrapper +wpa_supplicant

All I changed was to remove scan_ssid from the configuration file and it

If you need me to post anything else about my config let me know so it can
help others.

To summarise I use ndiswrapper 0.11 wpa_supplicant 0.2.5 with Linux 2.6.9
kernel on Fedora distro. With a linsys wrt54g ap/router and a linksys wmp54g
pci card.

With the following .config:


And my wpa_supplicant.conf:

# allow frontend (e.g., wpa_cli) to be used by all users in 'wheel' group
# home network; allow all valid ciphers

Thank you very much for your help.

That's fine, nothing is using that information. I would assume
ndiswrapper does not try to map the supported rates information into
IEEE 802.11b vs .11g. The main information is here: scan seems to work
and it returns wpa_ie.

Please use the CVS snapshot, not the 0.12rc3 prerelease. At least the
version from yesterday worked in my tests whereas 0.12rc3 required some
fixing for Linux 2.4.28 (but worked with the minor changes I did).

That's odd.. wpa_supplicant should scan again after five seconds. Could
you please re-test with -ddd on wpa_supplicant command line to enable
all debug messages.

Just leave that scan_ssid line out from the configuration and test
