It’s about 3,25 sec on my builtin wireless card. This is too much no ? Specialy if you want to write a application to scan for AP level.

The quick and dirty way to fix that (it works fine for me.. perhaps others..) :

  • Edit iw_ndis.c
  • Search for iw_get_scan function
  • change this
//if (time_before(jiffies, handle->scan_timestamp + 3 * HZ))
if time_before(jiffies, handle->scan_timestamp)
return -EAGAIN;

This simply drop the 3 sec wait for results.. Now I get search results in 0.25 sec ;) .. Please report if this works for you !
