Thanks Javier, I will look into the meshd-nl80211.c file and try this out.
I have also been testing the difference between 2 Ghz Mesh and 5 Ghz mesh with the same radios. If I create a secured mesh with channel 1 (2.412 GHz) everything runs fine. Encryption works great with HT20/HT40 and I get speeds upto 85Mbps on Iperf with 10 streams. If I create a secured mesh with channel 157 (5.785 GHz) on the same nodes I get the previous errors in HT20/HT40 modes. If I run the 5 GHz band without HT20/HT40 everything works fine. I wonder if the 5GHz HT20/HT40 mode is represented properly in the beacons. Where would I look to identify the modes in Authsae? BTW i'm using IW 3.6 Fred On Tue, Sep 11, 2012 at 1:53 PM, Javier Cardona <[email protected]> wrote: > Hi Fred, > > I don't have a solution, but I can provide some pointers.
