I've been running my box with this patch for the last 24 hours or so, on top of Michael's git tree + wireless-dev. Unfortunately, it does not seem to result in any real improvement to wireless performance. Using the txpower debugging support from Michael's tree, I see the measured TX power bouncing all over the place. The target TX power is 14.25 dBm, but my logs show it wandering from 4ish dBm all the way up to 17 dBm. It never stays at or above the target power long enough to complete the WPA handshake. Even when it does get near the target value, the next recalculation always seems to send it to one extreme or the other. On the plus side, when I set the attenuation values manually to Baseband: 3 RF: 5 tx_control: 0x30 I get a measured power output of 17dBm, which allows me to associate and stay associated (with performance about as good as the softmac driver). Hopefully, some tweaking of the start values and adjustment algorithm will make this driver usable for the majority of people currently using softmac. -- Will Dyson _______________________________________________ Bcm43xx-dev mailing list [email protected] https://lists.berlios.de/mailman/listinfo/bcm43xx-dev
