I am using hostap driver 0.4.9 for a Netgear MA401 card on Linux 2.6.11. The card was in Managed mode and connected to an access point first. When I changed either essid or mode by invoking ioctl() in my program, the delay is 12 ms. However, if I changed both essid and mode, the delay is 33 ms, which is more than the sum of two separate delays. Does anyone meet this before?
