Very strange. I don't have the problem of the router being deaf anymore. However further investigation into the code leads me to believe that the value is never set to GPIOF_INIT_HIGH. Which is confusing. Or am I not seeing the obvious?
ath79_wmac_set_ext_lna_gpio calls ar934x_set_ext_lna_gpio calls gpio_request_one and sets to GPIOF_DIR_OUT | GPIOF_INIT_LOW for the particular LNA GPIO. I reckon we need this to be GPIOF_INIT_HIGH in order for this to be in line with Felix's original patch. What bothers me is that if this patch isn't working, how is my device able to hear other devices just fine. I also agree with Felix, that value being passed in ath79_wmac_set_ext_lna_gpio as 0 or 1 is simply cosmetic, to produce an output of LNA0 or LNA1. It IS then later used to select AR934X_GPIO_OUT_EXT_LNA0 or AR934X_GPIO_OUT_EXT_LNA1 based on the provided value. I got lost in the ath79_gpio_output_select (maybe this is where the magic happens?) Best Regards, Chirag PS I own 2 N750s and they run in WDS AP and WDS AP+CLIENT mode and the devices see each other just fine. On Thu, Feb 6, 2014 at 5:37 PM, Luis E.
