Ubuntu GNOME - Wifi会导致shell(可能还有计算机)冻结。
Ubuntu GNOME - Wifi会导致shell(可能还有计算机)冻结。
提问于 2017-04-08 10:41:58
我使用Ubuntu16.04和gnome桌面一起安装在联想ideapad 700笔记本电脑上。
我学习的环境有一个非常不可靠的无线连接，这意味着它经常下降，但在10-20秒后，它是好的再去。问题是，它并不总是正确地重新连接，但是重新启动wifi模块似乎解决了这个问题，除非它冻结整个系统直到重新启动完成。
在syslog冻结期间没有相关的警告/错误，只有wifi驱动程序信息(连接/身份验证等)，所以一切都应该是正常的，但是驱动程序锁定系统，重新启动NetworkManager具有类似的效果，使计算机至少在一分钟内无法使用。
这是一个wifi驱动程序问题，或者更确切地说是一个外壳问题，还是其他什么问题？

是股票驱动程序冻结了系统，现在我使用的是lwfinger的驱动程序(https://github.com/lwfinger/rtlwifi_新的)，它现在工作得很好。
