Could you specify, what exactly parameter do you want to control? In the your askubuntu post, you refer to "iwconfig wlan0 sens" command, which can control too many aspects, including the selection of the best AP and the detection of channel busy condition.

Indeed, only airo, ipw2200, hostap, and prism54 support this feature, all of these are extremely old drivers. mac80211 does not support it. It appears to be used in the old drivers to ignore any signal quieter than the given sensitivity.

There isn't any open source and any mac802111 based driver with support for LCN40-PHY which is what sits in the BCM43142. You must be using wl.ko closed driver with very limited cfg80211 API. That makes things ever worse for you :( -- Rafał ^ permalink raw reply [flat|nested] 4+ messages in thread
