看看有沒有啟動藍芽裝置

product: BCM43142 802.11b/g/n [14E4:4365]
configuration: driver=bcma-pci-bridge latency=0

1. 目前作用中的驅動 bcma-pci-bridge
沒有抓到
serial: xx:xx:xx:xx:xx:xx
可能 驅動 bcma-pci-bridge 不是合適的驅動
2. https://help.ubuntu.com/community/WifiD ... er/bcm43xx
wl - Proprietary Broadcom STA Wireless driver
2-1. 安裝 bcmwl-kernel-source 或 broadcom-sta 驅動
Install either bcmwl-kernel-source (instructions below) OR the broadcom-sta (instructions at http://wiki.debian.org/wl) packages.
