I can only think of using iw or > iwconfig to disable power save per device. I'm using iwconfig currently to disable power saving for wireless card on my desktop after it boots up. However, from user perspective of things, it would be awesome if default was not hard coded in the kernel. Though, I must admit that if it wasn't for the problem discussed earlier in this thread, I probably wouldn't even notice power saving was set to on. I'm not sure if there are any other more subtle downsides of having power saving enabled. -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
