Thinkpad T410/T420 Debian 9 不扫描无线网

很多年前,经高人指点,
在笔记本上装Debian的wifi一直用下面的方法:

先在/etc/apt/sources.list 添加 non-free

然后用下面两句命令
apt update
apt install firmware-iwlwifi

一直非常顺利,直到最近用Debian 9 安装两台T410/T420遇到了同样的问题,用原来的方法安装firmware-iwlwifi但发现不了无线网,在网上找了不少帖子,但还是不得要领,所以需要专家指点。

下面是目前的状况:

    替换法,插入一块最普通的realtek usb无线网卡,15块钱那种的,看行不行,如果行,那么是你现在网卡驱动的问题,不行,就是配置的问题。
