Hi Ben,

I imagine, I am one of the guys you are refering to.
Within the thread "WLE600VX from PCEngines", I was trying to make 
working a HT80 IBSS connection with wpa_supplicant, but this connection 
was only set to 20MHz.
I was trying this with the 4.0 kernel, the 10.1.467-ct-14 firmware and 
the last version (git) of wpa_supplicant (2.5). By the way, has anyone 
tried this?

Then, due to this failure, I tried kernel 4.2 because Hannes Harm 
reported success to set HT80 IBSS. But I was not able to configure 
properly this kernel (compile OK, but the computer does not boot then).

@Ben, could you share a .config file for kernel 4.2? Do you think that 
Release14 CT firmware would be able to work? I will update the 4.2 
kernel, compile it and try to see
if I can set up the HT80 IBSS connection.
