我从http://wireless.kernel.org/en/users/Drivers/iwlwifi#Firmware为我的网卡N-7260安装了最新固件。我正在使用内核团队ppa的内核版本为3.14.01的Ubuntu 14.04 。这是我拥有的固件列表/lib/firmware
:
$ ls /lib/firmware/*iwl*7260*
/lib/firmware/iwlwifi-7260-8.ucode /lib/firmware/org.iwlwifi-7260-7.ucode
/lib/firmware/iwlwifi-7260-9.ucode /lib/firmware/org.iwlwifi-7260-8.ucode
目前看来版本9无法加载。如果删除版本8,则在启动时会看到以下消息:
sudo dmesg | grep iwl
[sudo] password for ozubu:
[ 6.121743] iwlwifi 0000:02:00.0: irq 62 for MSI/MSI-X
[ 6.133208] iwlwifi 0000:02:00.0: Direct firmware load failed with error -2
[ 6.133211] iwlwifi 0000:02:00.0: Falling back to user helper

[ 6.324950] iwlwifi 0000:02:00.0: no suitable firmware found!
所以,我的问题是:
我如何告诉Linux应该加载iwlwifi-7260-9.ucode
?
更新
奇怪的是,至少根据dmesg,现在加载的固件版本为8:
$ sudo dmesg | grep iwl
