英特尔无线7260驱动程序崩溃了，我该如何解决它？
我在Xubuntu 13.10和我的新联想X240笔记本电脑上遇到了Wifi问题。 有时司机崩溃了。

谢谢你的帮助。
有一个较新的固件文件可以解决一些不稳定问题。 请打开终端并备份当前固件：
cd /lib/firmware sudo mv iwlwifi-7260-7.ucode iwlwifi-7260-7.ucode.bak
现在下载更新的固件：
sudo wget https://git.kernel.org/cgit/linux/kernel/git/egrumbach/linux-firmware.git/plain/iwlwifi-7260-7.ucode
现在卸载并重新加载驱动程序，以便它看到新的固件：
（请注意， iwlmvm模块根据系统加载iwldvm或iwlmvm模块，所以在你能够删除iwlwifi之前你必须删除正确的iwlwifi 。我在这里使用了iwldvm ，但你应该使用iwlmvm if if你没有得到命令lsmod | grep iwldvm 。）
sudo modprobe -r iwldvm sudo modprobe -r iwlwifi sudo modprobe iwlwifi
没有必要运行sudo modprobe iwl?vm因为iwlwifi会自动处理它。
