在你点击复制之前:我已经尝试了Intel Corporation 7260 版本 63 没有无线问题。我已经加载了正确的微代码/lib/firmware
,并且正在运行内核版本 3.11。
我在全新安装 Kubuntu 13.10 时遇到了一些问题:我的无线网卡可以在实时 USB(使用 unetbootin 创建)上使用,但在已安装的系统上,驱动程序无法加载,并显示回溯错误,无法探测(硬件地址?),错误为 -12。有人有什么想法或建议吗?谷歌搜索无果。

安装程序使用内核 3.11.0-12-generic,已安装的系统运行内核 3.11.0-18-generic
在此先感谢您的时间。

首先,我会获得一个临时的有线以太网连接并完全更新您的系统(如果还没有的话):
sudo apt-get update && sudo apt-get -y upgrade
sudo reboot
检查日志以查看问题是否仍然存在:
dmesg | grep iwl
接下来,在您的 lsmod 中,我们看不到 iwlmvm。它是否正确加载?
lsmod | grep iwl
如果没有,请尝试加载它:
sudo modprobe iwlmvm
你的 /etc/modprobe.d/iwlwifi.conf 文件是否正确完成?我的是:
# /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
如果不正确,则需要恢复。如果您需要指导,请告知我们。
最后,这里有一些有趣的信息吗?
dmesg | grep 84:00
dmesg | grep -i error
84:00 是无线网卡的 PCI 总线。如果出现 ACPI 或 IRQ 错误,您可以尝试将 BIOS 重置为默认值。
一旦我们找到一些线索,我会根据需要编辑我的答案。

我最终通过从头安装 14.04 测试版然后在重新启动之前运行更新来修复它:
$ sudo su
# mount /dev/sda1 /target
# mount -o bind /dev /target/dev
# mount -o bind /sys /target/sys
# mount -o bind /tmp /target/tmp
# mount -o bind /proc /target/proc
# mount -o bind /etc/resolv.conf /target/etc/resolv.conf
# chroot /target
# apt-get update
# apt-get dist-upgrade
