在自定义桌面上运行 Ubuntu 14.04。我有 Encore 无线 N300 PCI-E 适配器（见此处）也可以通过此链接下载驱动程序。我了解到，解决连接问题的一个可能方法是卸载/重新安装无线驱动程序。似乎应该先尝试其他一些选项。
它只会断线一秒钟，然后重新连接。我可以看到 WiFi 图标不断从弱到强波动。
注意：我也在 Ubuntuforums 和 Unix Linux 上发布了几天，但尚未收到任何回复。我只是希望得到正确方向的推动。

还进入了网络管理器，并在之前空白的字段中锁定了 BSSID 号。我仍然看到 WiFi 图标在波动。通过运行以下命令找到 BSSID：
cat /var/log/syslog | grep -e etwork -e wlan | tail -n20
这给了我一个信息：
WLAN:0 WPA: GROUP
Rekeying completed with ( BSSID NUMBER)
[GTK=CCMP]
编辑/跟进：根据@Wild Man 的评论：我发现我唯一可以或需要更改的是 ipv6 中的“忽略”。之后，我在链接线程上运行了他的回答中提供的命令。这样做之后，我无法通过无线重新连接，直到我重新启动，然后需要很长时间才能打开开始页。我现在在线，但我的 WiFi 图标/网络仍然波动。以下是输出

编辑2尝试使用以下命令删除参数：
sudo rm /etc/modprobe.d/rtl8192ce.conf
之后我的读出是：grep -R "[[:alnum:]]" /sys/module/rtl8192ce/parameters

于是我跑了：
sudo modprobe -rv rtl8192ce
sudo modprobe -v rtl8192ce fwlps=0
确实将 fwlps 设置为 :N。但是我已完全断开连接，直到重新启动。
答案1
安装编译驱动程序所需的依赖项：
sudo apt-get install --reinstall linux-headers-generic linux-headers-$(uname -r) build-essential dkms
点击这里将最新的驱动程序下载到您的计算机，然后右键单击并提取此处。
然后按照以下说明编译驱动程序。
cd ~/Downloads/backports-3.16-rc1-1
make defconfig-rtlwifi
make
sudo make install
重新启动
当您升级内核时，您需要执行以下操作：
cd ~/Downloads/backports-3.16-rc1-1
make clean
make defconfig-rtlwifi
make
sudo make install
重启
感谢chili555找到并测试了此驱动程序，该驱动程序在两台不同的计算机上进行了编译。
