I have *no idea* what I'm looking at here: http://www.candelatech.com/examples/ventana/ventana-tcp-codel-dl_1462569548/chart-2.png 60 stations and 4sec latency? > http://www.candelatech.com/examples/ventana/ > > We'll run some tests on some of our higher-performing APs and see if > fq_codel works well there > too when we get a chance.... > > Thanks, > Ben > > -- > Ben Greear <[email protected]> > Candela Technologies Inc http://www.candelatech.com > -- Dave Täht Let's go make home routers and wifi faster!
