MacBook Pro 9.2 Ubuntu 14.04 完整链接质量无线错误

大家好,我在 Mac 上使用 Ubuntu 14.04,使用 wifi 大约 5 到 10 分钟后,它会随机显示信号已达到最大值,但互联网完全停止工作。这是我的 wifi 正常工作时显示的内容:

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

事情发生的时候是这样的:

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

      Power Management:off

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

我已经安装了以下驱动程序:

我认为您使用的是错误的驱动程序。请打开终端并执行以下操作:

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按预期工作。
