Exact same hardware and configuration: ath9k, around 240 wifi stations trying to connect to APs that can handle a bit less than 240 total, starting TCP traffic when stations are connected. It appears that the constant churn of stations going up and down is key, but of course that is par for the course, especially in the wifi stack. Some of our local wifi patches make the system work considerably faster when we have hundreds of wifi stations, so timing will be different on upstream kernels, and of course we could have bugs :) Thanks, Ben -- Ben Greear <greearb@...delatech.com> Candela Technologies Inc http://www.candelatech.com -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
