But in 11.3, the module doesn't work at all without this patch: https://patchwork.kernel.org/patch/125001/ To get it work a bit more usable, you have to apply this patch (w/o the one above): http://lkml.org/lkml/2010/8/14/25 There is one more problem: If the RTS and Fragment parameters are changed to the values used by the windows driver, you get nearly same performance downstream: wlan0 IEEE 802.11bg ESSID:"some" Mode:Managed Frequency:2.412 GHz Access Point: .....

Incoming data: (TCP_MAERTS): the performance of rt61pci is mostly the same as with rt61 (21 * 10^6 bits/sec). Outgoing data: (TCP_STREAM): the performance of rt61pci is about 63% of the performance of rt61 (Throughput is 13.2 * 10^6 bits/sec).

rt61pci works like this:

EAP Request, Identity [RFC3748] (sent by AP) EAP Response, Identity [RFC3748] (sent by supplicant)

30 s later EAP Request, Identity [RFC3748] (sent by AP) EAP Response, Identity [RFC3748] (sent by supplicant) EAP Request, EAP-TLS [RFC5216] [Aboba] sent by AP TLSv1 Client Hello (sent by supplicant) TLSv1 Server Hello (sent by AP) ...

(there could be even more tries until the AP sends the EAP-TLS-Request.)

Could you please fix this, too?

Hmm, create a separate bug for that. wpa_supplicant is out of scope for kernel. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
