encrypted modes don't work on ndiswrapper wireless adapters

[rodrifra]

Unencrypted connections work fine but WEP, WPA, etc.. doesn't work.
dmesg keeps showing the message

and no connection is established.

lsusb shows the usb key as

I've got a similar problem with rt2500 pci wifi card:

It also works without any problem on Sabayon...

Seeing the same problem with a Netgear WG111T while connecting to a WEP protected network.

[amjed (am-developer)]

Any luck ?? I have installed Ubuntu 9.10, and getting the same issue.. let me know if anyone has got a workaround for this ..

[zmago (zmago-fluks)]

I'm also having same issue... I'm using rt61pci card and driver in the kernel is corrupted that i'm losing my wireless connection constantly and ndiswrapper is also corrupted... i don't know what is with Ubuntu this time. I have at home also broadcom and realtek wireless card.. one is minipci and other is usb... with ndiswrapper i get again same issue and also kernel drivers are also corrupted for them. I hope we won't need to wait another 6 months for new release that this will be fixed...

[Master_Ne0 (master-ne0s-solutions)]

My WG111T was working the first time i installed it with ndiswrapper. Then, once connected to the internet, the Ubuntu update updated my system and when i restarted the WPA failed. I'm new here, though i am learning fast and have many years of development experience, let me know if there is anything i can do to help solve this bug.

[pascal (pascal-kolly)]

same problem with netgear wg511v2
I try to install xubuntu 9.04

[foxy123 (foxy)]

yes, it worked when i installed beta for the first time but stopped after the first update

[pascal (pascal-kolly)]

with xubuntu 9.04 and all update installed, WPA failed too ! wifi without password works

[Rene van Paassen (rene-vanpaassen)]

The following happens in the wpa_supplicant, driver_wext.c lines 2115 and further

#ifdef CONFIG_IEEE80211W
 switch (params->mgmt_frame_protection) {
 case NO_MGMT_FRAME_PROTECTION:
  value = IW_AUTH_MFP_DISABLED;
  break;
 case MGMT_FRAME_PROTECTION_OPTIONAL:
  value = IW_AUTH_MFP_OPTIONAL;
  break;
 case MGMT_FRAME_PROTECTION_REQUIRED:
  value = IW_AUTH_MFP_REQUIRED;
  break;
 };
 if (wpa_driver_wext_set_auth_param(drv, IW_AUTH_MFP, value) < 0)
  ret = -1;
#endif /* CONFIG_IEEE80211W */

the ndiswrapper wireless driver (and maybe others?) does not implement IW_AUTH_MFP, and returns -EOPNOTSUPP;

A fix is needed for ndiswrapper, which can be, for now, to accept the first two frame protection values, and fail on IW_AUTH_MFP_REQUIRED only.

[Rene van Paassen (rene-vanpaassen)]

I dug a bit deeper, created a patch, and filed a bug report for ndiswrapper too.

[pascal (pascal-kolly)]

Nice news Rene !
But what is the way to install your patch ? (i'm a completely new user !)
Best regards

[pascal (pascal-kolly)]

after the update 9.04 -->9.10 the wifi works well with wap too !

[rodrifra (rodrifra)]

Use patch command.

Use "man patch" to learn how to use it.

Being affected by this myself, I wrote this, which I hope helps: http://ubuntuforums.org/showthread.php?p=8426311

Big thanks to Rene for the patch!

[Graham Beneke (graham-beneke)]

When can we expect a patched package to be released as a SRU... or at least in a PPA ?

[pascal (pascal-kolly)]

Hello,

I need more help if it's possible !

before the patch
dmesg returns several lines like these:
[ 227.277096] ndiswrapper (iw_set_auth:1602): invalid cmd 12

after the patch (I follow the http://ubuntuforums.org/showthread.php?p=8426311 from Irving),
I have no more " invalid cmd 12 "
but the wifi WAP does not work

Many thanks for your help
Pascal

[Andy B (andy-bowdin)]

I got the same "invalid cmd 12" problem, but before getting around to patch saw
http://ubuntuforums.org/showthread.php?t=1284891

Setting a low priority for wpa_supplicant with

sudo renice +19 $(pidof wpa_supplicant)

makes the connection work, even though the invalid cmd message is still there!

[foxy123 (foxy)]

is it possible to do renice automatically at boot?

[Wizarth (wizarth)]

On 9.10 WPA2 support started working, but intermittently, as described here. The renice trick appears to work.

ndiswrapper around a Marvell Technology Group Ltd. 88w8335 [Libertas] 802.11b/g Wireless (rev 03)
ndiswrapper -l
wg511v2 : driver installed
 device (11AB:1FAA) present

The invalid cmd 12 seems to be irrelevant, as I receive this on the times the connection succeeds, as well as when it fails. syslog messages from ndiswrapper when the driver is loaded suggest the card does not suppose SSID scanning (?) yet NetworkManager is setting ap_scan , perhaps this is related?

[Wizarth (wizarth)]

After rebooting, the renice fix did NOT work.

[Marcelo Ruiz (marcelo-javier-ruiz)]

It is affecting me (I have a DLink DWL-G650M with a AR5513 chipset) after upgrading to Karmic. I think this bug is really mining Ubuntu's usability: connecting to a secured wireless connection is among the most common things someone could do with a computer. Is there any way to suggest to increase the importance of this bug?

[Wizarth (wizarth)]

After further testing, renice +19 (which lowers the priority) does work, if not immediately. If a connection is in progress, it may take a few retries. However, if applied before attempting the connection at all (such as switching to a tty before supplying NetworkManager with the password) then it will be successful.
However, it seems to make the connection slow to handshake, as the DHCP packets seem to be lost for up to a minute or so before getting through and getting a response. So this shouldn't be main lined.

This strikes me as definitely being some sort of race condition, which is mitigated by the renice, however in future releases when what is causing the race condition changes again, this may not continue to work.

To make this occur automatically, I've changed line 262 of /etc/wpa_supplicant/functions.sh from:
start-stop-daemon --start --oknodo $DAEMON_VERBOSITY \
to:
start-stop-daemon --start --nicelevel 19 --oknodo $DAEMON_VERBOSITY \

Please test and let me know if this works for anyone else.

[pascal (pascal-kolly)]

I have replaced the line 262 with : start-stop-daemon --start --nicelevel 19 --oknodo $DAEMON_VERBOSITY \
and reboot without effect !
The non-secure connection works and wpa does not work.

I try also many times : sudo renice +19 $(pidof wpa_supplicant)
without success.

Have a happy Chrismas

[foxy123 (foxy)]

have you patched ndiswrapper?

[Hans-Martin (hmm-heeg)]

In my experience, that is not necessary although it avoids the "invalid
cmd 12" errors. I have patched the wpa_supplicant startup script and
after this WLAN works well again, without the patched ndiswrapper (I
previously tried patching ndiswrapper, with little success)
It looks like there are a couple of problems at work here - at least one
is the mentioned race condition which should be tracked down and fixed.
Others seem to be more difficult to diagnose.

Cheers,
Hans-Martin

[Alexandru Bolboaca (alex-boly)]

I've tried the fix to wpa_supplicant startup script but the daemon still has priority 0. I know this because I tried renice and it says it had priority 0.
After renice, the wireless still doesn't work.

This issue is really annoying for me...

[Guillaume (guillaume-zin)]

Maybe the probelm is more wpa_supplicant related, see here for instance (there is a workaround to try) : https://bugs.launchpad.net/ubuntu/+source/wpasupplicant/+bug/207446

It's worked fine for me so far on Lucid but I will do upgrade and see if it works after that.

[foxy123 (foxy)]

Works fine for me on the latest 32-20 kernel. Though it takes a bit longer than usual to connect.

Is a fix released? I get this bug too with Ubuntu 10.4?!

For my particular adapter ("Realtek Semiconductor Co., Ltd. RTL-8185
IEEE 802.11a/b/g Wireless LAN Controller (rev 20)")
switching from ndiswrapper to the native kernel driver (rtl8180) in 10.4
worked. Before I tried that, I tried to apply various hacks that I found
on the net to wpasupplicant, without success.
But since it works now, there's no more messing with ndiswrapper for me...

I'm well aware that this is not helpful if your hardware is not
supported by a native driver, but if you have the same adapter you might
try this.

Hans-Martin

Hi,
since I've been using a WiFi card that is supported natively, I've not used ndiswrapper for a long time, so I can't say
whether it's ok in 13.04 - but thanks for asking :-)

[Julian Andres Klode (juliank)]

A fix was released upstream some time ago (1.57?), so it should be fixed now.
