台式机Ubuntu14.04上的WiFi不稳定


2

我已经在桌面上安装了Ubuntu 14.04,但现在WiFi连接出现问题。每次重新启动后,它都能正常运行,但一段时间后会掉线。有时恢复,有时不恢复。一开始,我可以通过单击WiFi连接启动器图标并重新连接来重新启动它。但是后来我搜索了互联网,发现了这两种解决方法:

echo "options iwlwifi 11n_disable=1" | sudo tee /etc/modprobe.d/iwlwifi.conf
sudo modprobe -rfv iwlwifi
sudo modprobe -v iwlwifi

sudo -i
echo "options rtl8723be fwlps=0"  >  /etc/modprobe.d/rtl8723be.conf
modprobe -r rtl8723be
modprobe rtl8723be
exit

都做了,现在我只是无法通过单击图标重新连接,需要重新启动PC。发现这可以重新启动连接而无需重新启动:

sudo service network-manager restart

这是无线信息脚本的输出:

请帮忙。

你做错了一切。您试图配置与无线适配器完全无关的驱动程序。

您需要以这种方式安装正确的驱动程序。

sudo add-apt-repository ppa:hanipouspilot/rtlwifi
sudo apt-get update
sudo apt-get install rtl8192cu-dkms linux-firmware

如果您没有破坏其他任何东西,则USB加密狗在重启后应该可以更好地工作。

删除由您创建的配置文件也很有意义

sudo rm /etc/modprobe.d/iwlwifi.conf
sudo rm /etc/modprobe.d/rtl8723be.conf

wasd @ notebook:〜$ sudo add-apt-repository ppa:hanipousptlot / rtlwifi无法添加PPA:'ppa:hanipousptlot / rtlwifi'。请检查PPA名称或格式是否正确。

感谢您的快速回复。已安装,尚不知道它是否正常工作。在最后一次网络管理器重新启动之后,没有连接中断。

测试一段时间。该驱动程序足够可靠。如果您确定解决方案是有帮助的,请单击左侧的对号以接受答案。
