OK, do you know where can I find this firmware? I just followed the wiki page to get the firmware, but it seems the same version as I am using. http://linuxwireless.org/en/users/Drivers/b43#device_firmware > >> [ 365.144349] b43-phy0 debug: b2062: Using crystal tab entry 19200 kHz. >> [ 365.412558] b43-phy0 debug: Chip initialized >> [ 365.413163] b43-phy0 debug: 64-bit DMA initialized >> [ 365.413356] b43-phy0 debug: QoS enabled > > Try disabling QoS via modparam.
