'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 traff= ic): Jan 6 11:02:25 d630 kernel: wlan0: [3a:41:c4:e3:1e:18] AMRR increasing rate 48 (txcnt=3D11 retrycnt=3D0) Jan 6 11:02:36 d630 kernel: wlan0: [3a:41:c4:e3:1e:18] AMRR increasing rate 72 (txcnt=3D11 retrycnt=3D0) Jan 6 11:03:02 d630 kernel: wlan0: [3a:41:c4:e3:1e:18] AMRR increasing rate 96 (txcnt=3D11 retrycnt=3D0) 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=3D11 retrycnt=3D10) Jan 6 11:04:09 d630 kernel: wlan0: [3a:41:c4:e3:1e:18] AMRR decreasing rate 48 (txcnt=3D13 retrycnt=3D7) Jan 6 11:04:10 d630 kernel: wlan0: [3a:41:c4:e3:1e:18] AMRR decreasing rate 36 (txcnt=3D43 retrycnt=3D24) Jan 6 11:04:11 d630 kernel: wlan0: [3a:41:c4:e3:1e:18] AMRR decreasing rate 24 (txcnt=3D84 retrycnt=3D38) Jan 6 11:04:12 d630 kernel: wlan0: [3a:41:c4:e3:1e:18] AMRR decreasing rate 22 (txcnt=3D25 retrycnt=3D9) Jan 6 11:04:12 d630 kernel: wlan0: [3a:41:c4:e3:1e:18] AMRR decreasing rate 18 (txcnt=3D31 retrycnt=3D11) Jan 6 11:04:13 d630 kernel: wlan0: [3a:41:c4:e3:1e:18] AMRR decreasing rate 12 (txcnt=3D29 retrycnt=3D11) Jan 6 11:04:13 d630 kernel: wlan0: [3a:41:c4:e3:1e:18] AMRR decreasing rate 11 (txcnt=3D53 retrycnt=3D28) Jan 6 11:04:18 d630 kernel: wlan0: [3a:41:c4:e3:1e:18] AMRR decreasing rate 4 (txcnt=3D17 retrycnt=3D7) Jan 6 11:04:20 d630 kernel: wlan0: [3a:41:c4:e3:1e:18] AMRR decreasing rate 2 (txcnt=3D11 retrycnt=3D10) 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=3D11 retrycnt=3D0) Jan 6 11:09:57 d630 kernel: wlan0: [3a:41:c4:e3:1e:18] AMRR increasing rate 11 (txcnt=3D11 retrycnt=3D0) Jan 6 11:10:30 d630 kernel: wlan0: [3a:41:c4:e3:1e:18] AMRR increasing rate 12 (txcnt=3D11 retrycnt=3D0) Jan 6 11:10:38 d630 kernel: wlan0: [3a:41:c4:e3:1e:18] AMRR decreasing rate 11 (txcnt=3D35 retrycnt=3D16) Jan 6 11:10:43 d630 kernel: wlan0: [3a:41:c4:e3:1e:18] AMRR decreasing rate 4 (txcnt=3D11 retrycnt=3D4) Jan 6 11:11:04 d630 kernel: wlan0: [3a:41:c4:e3:1e:18] AMRR increasing rate 11 (txcnt=3D11 retrycnt=3D0) 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=3D11 retrycnt=3D4) The rate decrease too much for using a browser (but I can still ping my gateway)=85 Regards, Olivier
