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

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.

Hi, So the trick here is that iwn uses the net80211 rate control API for doing things. Look at if_iwn.c for ratectl. There's a spot in the TX path where it calls it to look up the rate. It then converts that rate to the iwn PLCP format for the given transmission rate. You can google PLCP. Intel
