With the release of Wmediumd, I ran the same test with the simulated wireless
interface created by hwsim. The result is the same as above. plink show estab,
but the peers can not ping each other.
I suppose that hwsim create the virtual interface independent of the wireless
card on the PC, am I correct on this?
Thanks,

Hi Javier,
I have some question to add on to the previous 1,
what do you mean by multiple GTKs?
How do I verify that the card which I'm using now support multiple GTKs?
Thanks a lot,
Ming

Do you mean that to successfully ping the other peer, we need to use encryption?

Tx MGTK of peer 1= Rx MGTK of peer 2;
Rx MGTK of peer 1= Tx MGTK of peer 2;
but Tx MGTK and Rx MGTK of peer 1 is different.
Is this What you mean by support multiple GTKs?

I'm currently using AR9160 802.11 abgn card. From modinfo ath9k; nohwcrypt:
Disable harware encryption (int).
This means 'nohwcrypt=1' right?
I tested it again by ping to the other peer, but it still failed.
