Thanks! This looks reasonable. I did some cleanup and applied it. Based on a quick test, this seemed to be able to connect over 100 station vifs using WPA2-Personal to a single AP without major problems. Some resources are running out (just CPU?) that makes some of the 4-way handshakes fail (timeout?), but after couple of tries, I got 116 of 124 stations connected. This is with all interfaces starting at the same time; using some more latency there would likely make this quite a bit more robust. wpa_supplicant seemed to stop trying to reconnect in some cases, so this probably triggered some bugs that need to be addressed. Anyway, manual "wpa_cli -i<ifname> reassociate" on the missing eight vifs was able to get all the 124 stations connected at the same time. -- Jouni Malinen PGP id EFC895FA ^ permalink raw reply [flat|nested] 3+ messages in thread

Was this an ath5k or ath9k NIC (or something else?)
