Hi, Let's merge some more stuff into -HEAD first. it's likely there's some RF configuration problem which we can dig into in more detail but I can't do it whilst we've got broken Intel 5100 support (as then MY laptop doesn't work!) I have a spectrum analyser and I'm not afraid to use it. -adrian On 31 July 2013 06:36, Cedric GROSS <cg@cgross.info> wrote: > Hello, > >> >> Right, there's HT elements in there, so it looks likely you properly >> negotiated HT. >> >> >> > And the amrr output : >> > Test kernel: wlan0: [00:24:d4:97:80:20] amrr_node_init: non-11n node >> > Test kernel: wlan0: [00:24:d4:97:80:20] AMRR: nrates=0, initial rate >> 0 >> >> That's the initial "I don't know what you are yet" selection. >> >> > Test kernel: wlan0: [00:24:d4:97:80:20] amrr_node_init: 11n node Test >> > kernel: wlan0: [00:24:d4:97:80:20] AMRR: nrates=16, initial rate 128 >> >> Here it negotiated 11n.
