答案1
尝试按如下方式更改无线驱动程序的参数并检查报告的问题。
将 802.11bgn 更改为 802.11bg。
iwconfig wlan0 modu 11g
如果您有该选项，请将 wep 加密更改为 wpa2 (CCMP)(AES) 而不是 (TKIP)，这样效果会最好。
将路由器中的无线频道设置为 11，然后保存路由器配置并重新启动。
sudo iwconfig wlan0 channel 11
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 rtl8723be swenc=1 ips=0" | sudo tee /etc/modprobe.d/rtl8723be.conf
sudo modprobe -rfv rtl8723be
sudo modprobe -v rtl8723be
如果问题仍然存在，请尝试编译新的驱动程序。希望这能有所帮助！
