Path selection: iw meshX mpath dump Since you are using ath9k_htc, setting tx power should be working. For the setting of Tx power, please note that the it is in mBm and not dBm. iw meshX set txpower fixed 1800 for 18dBm
If you want the survey dump, perhaps look for ath9k device. ---- Chun-Yeow On Wed, Jan 21, 2015 at 5:13 PM, Steger, Marco via Devel <[email protected]> wrote: > Hi all, > > I'm planning some performance tests and experiments with 802.11s.
