Ubuntu 20.04：由于检测到微码 SW 错误，未找到 WiFi 适配器，iwlwifi 错误代码 5

我已经在我的机器上使用 Ubuntu 20.04 有一段时间了，之前遇到过没有 Wi-Fi 适配器的问题。

但是，我的修复方法（如下所述：Ubuntu 20.04-未找到 WiFi 适配器) 不再起作用。

这似乎是一个新的错误，因为错误消息不同。我的错误代码dmesg | grep iwlwifi（请参阅下面的完整日志）显示错误代码为 -5；而我之前的问题的错误代码为 110。

有人知道如何解决这个问题吗？

我的系统：

答案1

我找到了该问题的解决方案。正如@chili555 提到的，我的 63 版 iwlwifi 似乎已损坏 - 因此出现以下日志消息：

[   18.514384] iwlwifi 0000:93:00.0: Microcode SW error detected. Restarting 0x0.

根据此线程：https://bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/1948685，我发现了一个简单的技巧，可以强制我的系统使用最旧的版本，在我的情况下是 59 版本（没有损坏），通过执​​行以下命令：

  1. cd /lib/firmware
  2. sudo mv iwlwifi-ty-a0-gf-a0-63.ucode iwlwifi-ty-a0-gf-a0-63.ucode.b
  3. reboot

现在，当我重新启动时，59 版本的 iwlwifi 已被加载，并且我得到了我的 wifi 适配器。

更好的解决方案可能是遵循@chili555的建议，并更新 62 和 63 版本。但我很高兴它能正常工作并继续使用它。

答案2

在您的 dmesg 中，我们注意到：

iwlwifi：忽略未知参数“d0i3_disable” iwlwifi：忽略未知参数“lar_disable”

我怀疑您已将这些参数添加到文件中/etc/modprobe.d/iwlwifi.conf。通常，不需要添加驱动程序参数。就您而言，这些参数应用不当。请编辑文件并将其恢复为默认值：

# /etc/modprobe.d/iwlwifi.conf
# iwlwifi will dyamically load either iwldvm or iwlmvm depending on the
# microcode file installed on the system.  When removing iwlwifi, first
# remove the iwl?vm module and then iwlwifi.
remove iwlwifi \
(/sbin/lsmod | grep -o -e ^iwlmvm -e ^iwldvm -e ^iwlwifi | xargs /sbin/rmmod) \
&& /sbin/modprobe -r mac80211

我注意到有更高版本的固件可用。我还怀疑您的 -63 版本可能已损坏。让我们下载新副本。

通过以太网、网络共享或任何可能的方式建立有效的互联网连接，打开终端并执行以下操作：

cd /usr/lib/firmware/
sudo wget https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/iwlwifi-ty-a0-gf-a0-63.ucode
sudo wget https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/iwlwifi-ty-a0-gf-a0-66.ucode
sudo mv iwlwifi-ty-a0-gf-a0.pnvm iwlwifi-ty-a0-gf-a0.bak

重新启动并显示：

sudo dmesg | grep iwl
