-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Well ... apparently I should have suspected people to CC me directly as I'm not on this list, but nonetheless I got some catching up to do now :) (please CC me if you'd like a response within this next week :>) I'm open to suggestions - don't get me wrong, but I'm 99.9% sure that this is a WI driver issue with 5.x and not anything else. Others have reported this same problem over the last 6 months and I have seen absolutely no solutions their questions. Of course, it is very easy to say that it could be a MTU setting or interference, but I have personally tested over two dozen Prism 2.5 based cards using a variety of configurations, changes in settings, you name it - I've tried it (including trying to set the MTU lower). Something has changed since 4.9 that is causing hostap to run at half pace while uploading to associated stations. I guess what I'd really love to see is someone looking into the if_wi.c code and whatever else could be affecting this.. I'd be so bold as to offer $$ for such a fix (I am that desperate). I have, myself, spent countless hours, heck, weekends at a time, going through the code, removing this, changing that - with no success.. Then again, I do not claim to be a C programmer, much less someone that writes drivers. Just my two cents. My next step is to switch to Linux using the hostapd project, which I really don't want to do :<..Though, it is my understanding that OpenBSD doesn't have this problem - so I may try that if there simply will be no resolution to this matter.
