请检查并告诉我如何修复该问题。
答案1
我遇到了同样的问题，使用的是完全相同的笔记本电脑型号和网卡。看来我们的双网卡无法避免两个接口的干扰，而新卡可以自行做到这一点（请参阅此指导在 Debian wiki 中的 iwlwifi)。
我在错误报告中找到了解决方案（请参阅这里），其中还涉及创建文件/etc/modprobe.d/iwlwifi.conf并将其内容设置为：options iwlwifi 11n_disable=1 bt_coex_active=0 auto_agg=0 swcrypto=1。
如果该文件中已有一些内容，则可以使用以下命令覆盖它：
sudo echo "options iwlwifi 11n_disable=1 bt_coex_active=0 auto_agg=0 swcrypto=1" > /etc/modprobe.d/iwlwifi.conf
不要忘记重新启动笔记本电脑以使更改生效。
我现在正在用我的笔记本电脑写这篇文章，同时用我的蓝牙耳机听 YouTube，到目前为止没有问题。需要注意的是，这个问题在 Ubuntu 和 Fedora 上都发生过。
