MacBook Pro 9.2 Ubuntu14.04全链路质量无线错误

Question

嘿，伙计们，我在我的mac上使用Ubuntu14.04，在无线上网5到10分钟后，它随机显示信号是最大的，但互联网停止了所有的工作。下面是我的wifi在工作时所显示的情况：

wlan0     IEEE 802.11abg  ESSID:"vodafone-15B3"
      Mode:Managed  Frequency:2.417 GHz  Access Point: 08:7A:4C:EF:15:C4
      Bit Rate=144 Mb/s   Tx-Power=200 dBm
      Retry  long limit:7   RTS thr:off   Fragment thr:off
      Encryption key:off
      Power Management:off
      Link Quality=50/70 Signal level=-60 dBm
      Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
      Tx excessive retries:0  Invalid misc:0   Missed beacon:0

当它发生的时候：

wlan0     IEEE 802.11abg  ESSID:"vodafone-15B3"
      Mode:Managed  Frequency:2.417 GHz  Access Point: 08:7A:4C:EF:15:C4

      Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
      Tx excessive retries:0  Invalid misc:0   Missed beacon:0

我已安装下列驱动程式：

我相信你找错司机了。请打开一个终端并做：

sudo apt-get install firmware-b43-installer
sudo apt-get purge bcmwl-kernel-source

重新启动并告诉我们它是否正常工作。
