答案1
您的设备使用的驱动程序有问题，但有时如果我们向其中添加一些参数并更改路由器中的某些设置，我们可以使其工作，如果不行，我们将不得不编译一个新的驱动程序。
首先在您的路由器中更改802.11bgn为802.11bg。
其次，将 wep 加密更改为 wpa2 (CCMP)(AES) 而不是 (TKIP)，如果您有该选项，效果会最好。
第三，将路由器中的无线频道设置为 1 或 11，然后保存路由器配置并重新启动。
第四，进入屏幕右上角的网络管理器，单击编辑连接>无线选项卡，并将 IPV6 设置为忽略。
现在打开终端 CTRL+ALT+_T，然后为了准确起见，逐行复制并粘贴以下代码：
echo "options rtl8192ce swenc=1 ips=0" | sudo tee /etc/modprobe.d/rtl8192ce.conf
sudo modprobe -rfv rtl8192ce
sudo modprobe -v rtl8192ce
答案2
Realtek 驱动程序（对我来说是 RTL8188ee）从 Linux 内核 3.13（可能更早）开始就出现问题。内核开发人员似乎试图解决 RTLxxxx 驱动程序问题，但结果却导致问题无法解决。所以我想你得等着，直到有人再次修复它。另一种方法是降级到较旧的内核版本，例如 Ubuntu LTS 12.04 附带的版本。
答案3
我安装了Ubuntu 主线 4.0 内核在我的 64 位 Ubuntu 14.04 上，使用 ASUS PCE-N15，情况好多了！iwconfig现在报告 54 Mb/s，而不是 1 Mb/s！
