Rtl8187se & 2.6.30.3 - almost, but no wpa

Rtl8187se & 2.6.30.3 - almost, but no wpa

[Dan Farrell]

Greetings esteemed linux devs!  I thank you all. 

I write to report limited success with the realtek rtl8187se wireless b/g network card driver in 2.6.30.3 staging. 

The driver works AFAICT with open networks. The driver does not appear to work yet with WPA although it appears to be implemented.  I haven't yet tested WEP although I can if testers are in short supply. 

I send this report because there are various requests for feedback on the driver in the code base.  

I want to help!  I will gladly provide any information that can assist. I will follow with bits from dmesg if I can figure out what seems relevant.  

Guidance would be greatly appreciated.  What can I do to help?  Is this the right place to be posting feedback?   

With great respect, 
Dan farrell dan@spore.ath.cx

I have not seen any issues in dmesg that appear relevant; but have
pulled from verbose debug output of wpa_supplicant the following lines:

WPA: IE in 3/4 msg does not match with IE in Beacon/ProbeResp
(src=00:13:46:5f:f3:c4) WPA: WPA IE in Beacon/ProbeResp -

wpa_driver_wext_disassociate

note that RSN IE in Beacon/ProbeResp does not match WPA: RSN IE in 3/4
msg.  in the second to last byte, the former shows 00 and the later
shows 0c.  

Digging into source code...

Internet suggests disabling WME in hostapd (supplying my testing access
point).  wpa_supplicant now says:

ioctl[SIOCSIWENCODEEXT]: Invalid argument
Driver did not support SIOCSIWENCODEEXT
WPA: Failed to set GTK to the driver.
RSN: Failed to install GTK
RSN: Failed to configure GTK

Hope this can help me and others.

module michael_mic solved this.  

WPA working, without WME.
