由于某种原因，昨天我还可以正常使用 wifi 连接，但现在（第二天）我似乎无法连接到任何无线点。我不确定，但可能是我昨天更新了内核，这可能导致了这种情况。
我尝试按照描述的方法修复该问题使用 iwlwifi 卡时无线网络不显示因为我遇到了同样的错误：
错误！模块 backport-iwlwifi 的 /var/lib/dkms/backport-iwlwifi/8324/5.13.0-39-generic/x86_64/dkms.conf 包含与此内核/架构不匹配的 BUILD_EXCLUSIVE 指令。这表示不应构建它。已跳过。
尝试重新安装“backport-iwlwifi-dkms”时，似乎这并没有解决问题。虽然在尝试安装版本“9340-0ubuntu4”之前尝试删除命令会导致错误
sudo dkms remove backport-iwlwifi/8324 -k 5.13.0-39-generic 导致错误 错误！DKMS 树中没有模块：backport-iwlwifi 8324 的实例。
我还是尝试了建议的解决方案，因为我不知道还能做什么，但它似乎没有解决问题。我的内核版本是 5.13.0-39-generic。一些信息：
lspci -v:

在dmesg | grep iwl命令中 iwl 是红色的，在lsmod |grep iwlwifi命令中 iwlwifi 也是红色的。不知道现在该怎么办，会不会是硬件问题？
抱歉，如果布局不是很好，这是我第一次发帖子。
