我有一个 USB 无线网络,它的名字和司机在维基百科中。在Ubuntu系统上,立即被识别并连接良好。在 Debian 中,没有显示无线网络。这是因为我没有安装相应的驱动吗?怎么修?

编辑
问题仍然没有解决,我尝试从非免费安装固件,但仍然不起作用。安装程序也无法识别 .bin 文件。看来相应的固件位于正确的目录中,这里是一些输出:
/lib/firmware$ ls -al

答案1
答案2
下载firmware-ralink_0.43_all.deb
来自这里
wget http://ftp.us.debian.org/debian/pool/non-free/f/firmware-nonfree/firmware-ralink_0.43_all.deb
提取它:
ar vx firmware-ralink_0.43_all.deb
你将得到3个文件:
x - debian-binary
x - control.tar.gz
x - data.tar.xz
解压缩data.tar.xz
文件:
tar xf data.tar.xz
cd
并/lib/firmware
列出二进制文件:
rt2561.bin rt2561s.bin rt2661.bin rt2860.bin rt2870.bin rt3070.bin rt3071.bin rt3090.bin rt3290.bin rt73.bin
将其复制rt2870.bin
到您的 USB 然后连接它,安装程序将检测并安装固件,以使 wifi 正常工作。
