没驱动吧。用

代码: 全选

sudo lshw -C network
看看网卡是什么型号的。直接把输出结果复制粘贴上来就行,不用截图

rtl8822be的网卡,18.04应该直接能支持了。
如果你装的是双系统,可能需要在windows下面把快速启动功能关掉
如果还不行,你用的thinkpad具体是什么型号的?

代码: 全选

dmesg | egrep -i '(net|rtl)'
的输出是什么

你升级过bios没有?
最新版是1月3日发布的1.14 https://think.lenovo.com.cn/support/dri ... Pad%20A485
你没有装双系统,就用它的光盘版升级程序
如果升级了bios还是不行,可以试试ubuntu 18.10。不用安装,直接试用,看能不能用无线
