Worked in Ubuntu 7.10 - Not in 8.04  2008/04/30 03:26

I'm experiencing an issue of being unable to associate with a WPA-PSK AP after updating from Ubuntu Gutsy to Hardy. Wireless setup with WG511v1 and ndiswrapper (tried both versions 1.50 & 1.52). Also tried with Network Manager and Wicd but same symptoms and problem. Seems as though ndiswrapper is unable to obtain the correct key to connect with the AP. Wireless setup and configuration worked under Gutsy but unable to get it to work under Hardy. The native prism54 drivers for the Netgear WG511v1 have been blacklisted, and here's the pertinent info:

ndiswrapper version 1.50-1ubuntu1 (hardy)

wpasupplicant version 0.6.0+0.5.8-0ubuntu2 (hardy)

gnome-keyring version 2.22.1-1 (hardy)

libpam-gnome-keyring version 2.22.1-1 (hardy)

network-manager version 0.6.6-0ubuntu5 (hardy)

wicd version 1.4.2-1 (apt.wicd.net)

:~$ ndiswrapper -v
utils version: '1.9', utils version needed by module: '1.9'
module details:
filename: /lib/modules/2.6.24-16-generic/ubuntu/misc/ndiswrapper/ndiswrapper.ko
version: 1.52
vermagic: 2.6.24-16-generic SMP mod_unload 586

:~$ ndiswrapper -l
netwg511 : driver installed
device (1260:3890) present (alternate driver: prism54)


[Edit#1] Noticed that the keyring management has changed quite a bit in Hardy. Don't know if this change has any effect on ndiswrapper's operation and/or interface with the revised keyring functions.

[Edit#2] Verified that ndiswrapper & netwg511 driver works for open APs.

[Edit#3] More info but still no resolution yet...

Tested with the following latest updates without success:

gnome-keyring version 2.22.2-0ubuntu1 (hardy-updates)

libpam-gnome-keyring version 2.22.2-0ubuntu1 (hardy-updates)

:~$ ndiswrapper -v

^^^^^^^^^^^^^^^^^^^^^^^^^^^
This is INCORRECT since the driver ndiswrapper+netwg511 worked with WPA under previous versions of Ubuntu from 6.06 through 7.10 (Gutsy).

Scanning for the WiFi networks under Hardy (8.04) reveals:

:~$ sudo iwlist scan

eth0 Interface doesn't support scanning.

wmaster0 Interface doesn't support scanning.

Noticed that when working under Gutsy the following differences were observed:

Group Cipher : WEP-40
Pairwise Ciphers (1) : WEP-40

All other parameters were the same as reported above under Hardy.
