But yes, there is (seemingly) no reason to this besides preventing interoperability with standard consumer devices. Also, the PTK stuff is not the only difference, the documents below detail the others (I didn't know of them at the time of writing my previous message). https://libdrc.org/docs/re/wifi.html has some reverse engineered information on the Wii U's differences (N.B. DRC refers to the gamepad (client) and DRH to the Wii U (access point)). https://github.com/rolandoislas/drc-hostap/blob/master/README.DRC describes the changes in the patched wpa_supplicant. https://github.com/rolandoislas/drc-hostap/compare/2462f34..5c6490e shows the changes from upstream.

That does sound like the most sensible option. Thank you, I guess I'll start hacking on this with the caveat I don't really know what I'm doing. _______________________________________________ Hostap mailing list Hostap@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/hostap
