'wlandebug +rate' might shed some light on this one. Hi, it's just very slow transfer rates. I didn't know wlandebug, thanks for the tips. Here are the result just after a boot, during pinging my gateway (few traffic): Jan 6 11:02:25 d630 kernel: wlan0: [3a:41:c4:e3:1e:18] AMRR increasing rate 48 (txcnt=11 retrycnt=0) Jan 6 11:02:36 d630 kernel: wlan0: [3a:41:c4:e3:1e:18] AMRR increasing rate 72 (txcnt=11 retrycnt=0) Jan 6 11:03:02 d630 kernel: wlan0: [3a:41:c4:e3:1e:18] AMRR increasing rate 96 (txcnt=11 retrycnt=0) Now, I start xorg and a start a browser: Jan 6 11:04:04 d630 kernel: wlan0: [3a:41:c4:e3:1e:18] AMRR decreasing rate 72 (txcnt=11 retrycnt=10) Jan 6 11:04:09 d630 kernel: wlan0: [3a:41:c4:e3:1e:18] AMRR decreasing rate 48 (txcnt=13 retrycnt=7) Jan 6 11:04:10 d630 kernel: wlan0: [3a:41:c4:e3:1e:18] AMRR decreasing rate 36 (txcnt=43 retrycnt=24) Jan 6 11:04:11 d630 kernel: wlan0: [3a:41:c4:e3:1e:18] AMRR decreasing rate 24 (txcnt=84 retrycnt=38) Jan 6 11:04:12 d630 kernel: wlan0: [3a:41:c4:e3:1e:18] AMRR decreasing rate 22 (txcnt=25 retrycnt=9) Jan 6 11:04:12 d630 kernel: wlan0: [3a:41:c4:e3:1e:18] AMRR decreasing rate 18 (txcnt=31 retrycnt=11) Jan 6 11:04:13 d630 kernel: wlan0: [3a:41:c4:e3:1e:18] AMRR decreasing rate 12 (txcnt=29 retrycnt=11) Jan 6 11:04:13 d630 kernel: wlan0: [3a:41:c4:e3:1e:18] AMRR decreasing rate 11 (txcnt=53 retrycnt=28) Jan 6 11:04:18 d630 kernel: wlan0: [3a:41:c4:e3:1e:18] AMRR decreasing rate 4 (txcnt=17 retrycnt=7) Jan 6 11:04:20 d630 kernel: wlan0: [3a:41:c4:e3:1e:18] AMRR decreasing rate 2 (txcnt=11 retrycnt=10) Jan 6 11:06:07 d630 wpa_supplicant[413]: CTRL-EVENT-SCAN-RESULTS Jan 6 11:09:48 d630 kernel: wlan0: [3a:41:c4:e3:1e:18] AMRR increasing rate 4 (txcnt=11 retrycnt=0) Jan 6 11:09:57 d630 kernel: wlan0: [3a:41:c4:e3:1e:18] AMRR increasing rate 11 (txcnt=11 retrycnt=0) Jan 6 11:10:30 d630 kernel: wlan0: [3a:41:c4:e3:1e:18] AMRR increasing rate 12 (txcnt=11 retrycnt=0) Jan 6 11:10:38 d630 kernel: wlan0: [3a:41:c4:e3:1e:18] AMRR decreasing rate 11 (txcnt=35 retrycnt=16) Jan 6 11:10:43 d630 kernel: wlan0: [3a:41:c4:e3:1e:18] AMRR decreasing rate 4 (txcnt=11 retrycnt=4) Jan 6 11:11:04 d630 kernel: wlan0: [3a:41:c4:e3:1e:18] AMRR increasing rate 11 (txcnt=11 retrycnt=0) Jan 6 11:11:09 d630 wpa_supplicant[413]: CTRL-EVENT-SCAN-RESULTS Jan 6 11:11:09 d630 kernel: wlan0: [3a:41:c4:e3:1e:18] AMRR decreasing rate 4 (txcnt=11 retrycnt=4) The rate decrease too much for using a browser (but I can still ping my gateway)… Regards, Olivier
