rtl8192ce连接在桌面上下降和波动，14.04 64bit与Encore N300 PCI-E
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）该驱动程序也可以在此链接下载。 我已经读过可能解决连接问题的方法是卸载/重新安装无线驱动程序。 似乎应该首先尝试其他一些选项。
它只会暂停连接一秒钟，然后重新连接。 我可以看到WiFi图标不断波动从弱到强。
注意：我也在Ubuntuforums和Unix Linux中发布了这几天，但我还没有回复。 我只是想朝着正确的方向努力。

还进入了网络管理器并锁定了以前空白字段中的BSSID号码。 不过，我看到WiFi图标波动。 BSSID通过运行找到：
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/关注：Per @Wild Man’comment：我发现我唯一可以或需要改变的是ipv6中的“忽略”。 接下来，我在链接的线程上运行了他的答案中提供的命令。 在这样做之后，我无法通过无线重新连接，直到我重新启动，然后打开启动页面需要很长时间。 我现在在线，但我的WiFi图标/网络仍在波动。 这是输出

所以我跑了：
sudo modprobe -rv rtl8192ce sudo modprobe -v rtl8192ce fwlps=0
这确实设置了fwlps：N。 但是我完全断开连接，直到重启。
