无线网卡是英特尔的5300.

执行命令~$ lsmod
其中cfg80211 487424 1 mac80211

用命令：sudo modprobe iwlwifi
modprobe: ERROR: could not insert 'iwlwifi': Exec format error

小白一个，求指教！

提供更多背景信息，在这之前对 iwlwifi.ko 做了什么
执行以下指令将结果全部复制贴上来

代码：全选

uname -a
find /lib/modules/ | grep "iwl.*\." | xargs ls -l
sudo modinfo iwlwifi | grep -v "alias\|parm\|firm"
sudo modprobe iwlwifi; dmesg | tail -n30
sudo lshw -numeric -C net

之前做到这两步后出问题了：
make -C /lib/modules/$(uname -r)/build M=$(pwd)/drivers/net/wireless/iwlwifi modules
sudo make -C /lib/modules/$(uname -r)/build M=$(pwd)/drivers/net/wireless/iwlwifi INSTALL_MOD_DIR=updates \modules_install

不知初始问题是什么，使用 4.4 内核的 iwlwifi 遇到何种问题。
若打算使用其它版本内核的 iwlwifi，不如直接升级到 Linux 4.8

那不能重新进行无线网卡驱动，覆盖掉原来的操作吗？
现在执行~$ ifconfig
eth0 ...
lo ...
没有无线网卡

我的无线网卡试试Intel 5300的。

打错字不好意思，是我的无线网卡是Intel 5300

最后我还是重新装了一边系统。
