Thomas, Dave, Adrian, Johannes, Thanks for comments and encouragement. I bought the TP-Link TL-WA901ND access point and TP-Link TL-WDN4800 PCIe card. Had no problem getting them talking to each other with ath9k, and the rate table contains 52 entries, so plenty to start out with.
I've written a follow-up post about it if anybody's interested: http://www.openias.org/bayesian-wifi-materials-and-methods Cheers, Björn On Wed, Oct 26, 2016 at 7:56 AM, Johannes Berg <johan...@sipsolutions.net> wrote: > >> The intel 7260 and later parts also allow user controllable rate >> control and provide transmit completion feedback, but I don't know >> whether it's enough for your needs. > > Perhaps.
