14.04 版 RTL8723BE 的 WiFi 问题

14.04 版 RTL8723BE 的 WiFi 问题

即使经过大量故障排除后,WiFi 仍然无法连接。

  1. WiFi 连接需要很长时间。
  2. 即使成功连接(这种情况很少见),互联网连接最多也只能工作 10 分钟,之后就会停止发送和接收数据。

输出至lspci -knn | grep Net -A3

无线信息脚本结果

按照链接中的步骤操作瑞昱科技直到点。事情是这样的:

输入

sudo add-apt-repository ppa:hanipouspilot/rtlwifi
sudo apt-get update
sudo apt-get install rtlwifi-new-dkms

此后,就根本不存在任何无线连接的选项。

没有无线选项

输出为了dkms status
