Not if PHY is running (reset sets the channel after phy reset + rfbuffer setup), there is a way to do a synth-only channel change using an access method to rf registers (rfbus grant) but it's not implemented yet on ath5k (+ it's only for post-AR5413 chips + it doesn't always work so you have to fallback to a full reset)... > for tx side i set the txpower tables for the channel before changing channel. > I found this helps in improving successful transmission. > Interesting, how does it help on improving successful transmission ?

For now use ath5k_hw_reset, i'm working on introducing some small init/reset functions for phy and pcu and maybe implement synth-only channel change but it wont happen anytime soon (after September). You can do it yourself if you want, check out Sam's HAL or Legacy HAL (from Atheros). -- GPG ID: 0xD21DB2DB As you read this post global entropy rises.
