我刚刚在 Dell Optiplex 上安装了 18.04。台式机使用有线网络连接到互联网，没有连接任何 wifi 适配器或加密狗。我遇到了持续写入磁盘和冻结的问题。查看 sysylog 似乎显示了许多与 mt7601u 相关的问题，据我所知，mt7601u 是一个 wifi 适配器，因此不需要。
这是 iwconfig 的结果：
eno1 no wireless extensions.
lo no wireless extensions.
我运行了 rfkill list all 和 sudo modprobe mt7601u && dmesg | grep mt76。结果如下：

这些错误在整个 sysylog 中反复出现。您知道如何关闭或删除 mt7601u 吗？
答案1
我建议你将模块列入黑名单。从终端：
sudo -i
modprobe -r mt7601u
echo “blacklist mt7601u” >> /etc/modprobe.d/blacklist.conf
exit
一切已准备就绪。
