Same bug here. It's completely annoying when making voip calls or playing FPS games. I did some research on this problem: Exact every 2 minutes in syslog I get "wpa_supplicant[1112]: CTRL-EVENT-SCAN-RESULTS" and exactly in this moment all my wireless traffic if "paused" for 5-6 seconds, if I run constant ping on my access point I get: 64 bytes from 10.0.2.1: icmp_seq=7 ttl=64 time=0.540 ms 64 bytes from 10.0.2.1: icmp_seq=8 ttl=64 time=0.561 ms 64 bytes from 10.0.2.1: icmp_seq=9 ttl=64 time=6442 ms 64 bytes from 10.0.2.1: icmp_seq=10 ttl=64 time=5442 ms 64 bytes from 10.0.2.1: icmp_seq=11 ttl=64 time=4443 ms 64 bytes from 10.0.2.1: icmp_seq=12 ttl=64 time=3443 ms 64 bytes from 10.0.2.1: icmp_seq=13 ttl=64 time=2445 ms 64 bytes from 10.0.2.1: icmp_seq=14 ttl=64 time=1446 ms 64 bytes from 10.0.2.1: icmp_seq=15 ttl=64 time=447 ms 64 bytes from 10.0.2.1: icmp_seq=16 ttl=64 time=0.496 ms The same thing will happen if I run in console: # iwlist wlan0 scan
So the I think the problem is in NetworkManager or nm-applet are running scan every two minutes, not in wpa_supplicant itself. Ifound a workaround: 1. stop NetworkManager (/etc/init.d/network-manager stop) 2. write your wireless config for wpa_supplicant (my is simple I have open wireless network without password) 3. run wpa_supplicant (wpa_supplicant -iwlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf) 4. get IP (dhclient3 wlan0) I'm using ThinkPad X60 with Ethernet controller: Atheros Communications Inc.
