Hello Ubuntu team,
I managed to compare the output of NetworkManager on Fedora, where it
works properly, and I found that the problem was related to a wrong
wpa_supplicant driver selection made by Ubuntu's NetworkManager.
I downloaded the latest NetworkManger Ubuntu sources (network-
manager_0.6.3-2ubuntu5), and I found that the patch debian/patches/10
-rml-wpa-workarounds.patch is where the problem started. There's code
that detects if we're using ndiswrapper and sets a wpa_driver variable
to "ndiswrapper", after that it changes code where wext is hardcoded to
code where it uses the value of the wpa_driver variable.
Original code (debian/patches/10-rml-wpa-workarounds.patch):
---------------------------
+ if (!strcmp (kernel_driver, "ath_pci"))
+ wpa_driver = "madwifi";
+ else if (!strcmp (kernel_driver, "ndiswrapper"))
+ wpa_driver = "ndiswrapper";
+ else
+ wpa_driver = "wext";
---------------------------
This should be rewritten like this:
---------------------------
+ if (!strcmp (kernel_driver, "ath_pci"))
+ wpa_driver = "madwifi";
+ else if (!strcmp (kernel_driver, "ndiswrapper"))
+ wpa_driver = "wext";
+ else
+ wpa_driver = "wext";
---------------------------
and there's also a line that should be changed on the next patch
(debian/patches/11-j-hostap-supplicant-driver.patch). You should change
the first occurrence of:
---------------------------
wpa_driver = "ndiswrapper";
---------------------------
to:
---------------------------
wpa_driver = "wext";
---------------------------
That way we'll be able to compile that code and make it work with the
newest versions of the ndiswrapper module from the ndiswrapper website
(1.23).
After this everything should work properly, either with encrypted or
unencrypted networks. I recommend using ndiswrapper 1.23 from
ndiswrapper website since it's more robust than the version that comes
with Ubuntu's linux-image.
I'm sorry, but I'm not a developer and I don't really know how to
package this properly. I'm reading the Ubuntu packaging manual. Expect
fixed packages posted soon.
