![RHEL7 无线配置不可用](https://linux22.com/image/681503/RHEL7%20%E6%97%A0%E7%BA%BF%E9%85%8D%E7%BD%AE%E4%B8%8D%E5%8F%AF%E7%94%A8.png)
我正在尝试在 RHEL7 NUC 上使用无线 USB 密钥。适配器显示在“ifconfig”中:
eno1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 192.168.0.21 netmask 255.255.255.0 broadcast 192.168.0.255

ether b8:ae:ed:7d:ce:5a txqueuelen 1000 (Ethernet)
...
enp0s20f0u3: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500

ether 00:14:d1:d8:cc:0f txqueuelen 1000 (Ethernet)
...
但是 NetworkManager 中没有可用的无线配置选项,所以我无法选择 SSID/wpa2 密码等等。
我发现了一个讨论类似问题的帖子对于 centos。按照那里的建议,似乎我没有为无线适配器加载内核模块:
# lspci -nn | grep -i net
00:1f.6 Ethernet controller [0200]: Intel Corporation Ethernet Connection I219-V [8086:1570] (rev 21)

# grep -i 8086 /lib/modules/*/modules.alias | grep -i 24f3 | tee -a q

# lsmod | grep wifi
# (NOTHING)
# modprobe iwlwifi
# lsmod | grep wifi
iwlwifi 112501 0
cfg80211 514740 1 iwlwifi
但是,按照该线程中的建议重新启动 NetworkManager 后:
# service network stop
# service wpa_supplicant stop
# chkconfig --level 12345 network off
# chkconfig --level 12345 wpa_supplicant off
# chkconfig --level 2345 NetworkManager on
# service NetworkManager restart
NetworkManager 中仍然没有显示无线配置选项。我确实安装了 NetworkManager-wifi 包:
# rpm -qa | grep NetworkM

NetworkManager-1.0.0-16.git20150121.b4ea599c.el7_1.x86_60
我还需要做什么才能使 wifi 适配器可供 NetworkManager 使用。或者,也许更简单,如何在命令行上配置无线适配器?
答案1
事实证明需要高于 3.10 的内核以及更新的固件。
