我正在尝试诊断我在我的设备上看到的问题LibreELEC.tv 9.0 Alpha 006安装。
如果我运行实时系统，并转到控制台 (CTRL+ALT+F3)，以下是 dmesg 显示的内容：
$ dmesg | grep 3945
[ 7.454039] iwl3945: Intel(R) PRO/Wireless 3945ABG/BG Network Connection driver for Linux, in-tree:s
[ 7.454043] iwl3945: Copyright(c) 2003-2011 Intel Corporation
[ 7.454045] iwl3945: hw_scan is disabled
[ 7.454178] iwl3945 0000:0c:00.0: can't disable ASPM; OS doesn't have ASPM control

[ 7.508461] iwl3945 0000:0c:00.0: Detected Intel Wireless WiFi Link 3945ABG
[ 7.509635] ieee80211 phy0: Selected rate control algorithm 'iwl-3945-rs'
[ 7.532150] iwl3945 0000:0c:00.0: loaded firmware version 15.32.2.9
现在，如果我在此系统上安装 debian（测试）（在此期间我没有更改 BIOS 中的任何内容）。这是我所看到的：
$ dmesg | grep 3945
[ 8.717721] iwl3945: Intel(R) PRO/Wireless 3945ABG/BG Network Connection driver for Linux, in-tree:s
[ 8.717724] iwl3945: Copyright(c) 2003-2011 Intel Corporation
[ 8.717810] iwl3945 0000:0c:00.0: can't disable ASPM; OS doesn't have ASPM control
[ 8.771950] iwl3945 0000:0c:00.0: Tunable channels: 13 802.11bg, 23 802.11a channels

[ 9.756622] iwl3945 0000:0c:00.0 wlp12s0: renamed from wlan0
因此，上面的内容表明我的卡可以工作，它仅作为参考，因为我的目标是使其在 LibreELEC.tv 安装上工作。
我已经关注 dmesg 输出有一段时间了，但我无法理解 LibreELEC.tv 启动期间丢失的黑魔法。与默认 Debian（测试）安装相比，iwl3945 驱动程序的行为与 LibreELEC.tv 安装不同，可能缺少什么？
最后，我希望看到 wlan0 接口列在 ifconfig 的输出中。目前我只看到：
