Dear Alex,
Can you send me updates in driver to make it support 5/10Mhz channel both at client and AP ath9k. Also how can i set my channel to 5/10Mhz in settings.

    Thank you Adrian. Yes I know, but I can not get it working with AR9390
    (enterprise) chip too. :(

Dear all,

I am also trying to reduce channel width to 5/10 MHZ. So far I managed to see the code inside the ath9k driver. More particulary in hw.c and ar9003_phy.c the functions "IS_CHAN_QUARTER_RATE" and "IS_CHAN_HALF_RATE" exist. These functions take values from the hw.h file, #define IS_CHAN_HALF_RATE(c) (((_c)->channelFlags & CHANNEL_QUARTER) !=0 . From what I understand, this function changes the clockrate value which in turn affects the PLL value. In a paper reported that these values are responsible for channel width.

The question is how can I enable these half/quarter rate functions. For example when you want to set the channel width to 40MHZ, you simply type: iw dev "XXX" set channel "X" HT40+ . Also is this possible for AR9380 chipset and if so, is this possible via driver configuration? Is there anyone of you who achieved this?

Best Regards

Tomas
