答案1
这是一个已知问题，有说明如何手动安装驱动程序 https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1220146/comments/125
答案2
谢谢你，链接在上面工作正常，如果在尝试时出现错误“我不知道如何处理 rt2x00...”
sudo dkms add –m rt2x00 –v VV
sudo dkms build –m rt2x00 –v VV
sudo dkms install –m rt2x00 –v VV
sudo dkms install –m rt2x00 –v VV --force
请尝试：
sudo dkms add rt2x00/VV
sudo dkms build rt2x00/VV
sudo dkms install rt2x00/VV
sudo dkms install rt2x00/VV --force
至少它对我有用。
