无法添加新连接：(2) 如果未给出 AP 路径，则需要具有有效 SSID 的“无线”设置

我目前正在尝试从 arch-linux 共享无线网络。网络设置中有一个按钮可以让我执行此操作：

网络设置“用作热点...”

我点击了“打开”按钮，因为这正是我正在寻找的！

Wi-Fi 热点弹出窗口打开

但在终端中使用以下命令：

$ sudo journalctl -xef

我仍在阅读这里和那里的一些文档，但除了此处某些源代码中的确切错误消息之外，我还没有找到与此错误有关的任何内容：

https://github.com/lcp/NetworkManager/blob/master/src/nm-device-wifi.c#L1211

一位朋友在 Fedora 上进行了测试，它开箱即用，他ESSID在这里找到了与他创建的 wifi 相匹配的设置：

/etc/sysconfig/network-scripts/ifcfg-Hotspot

但我在 Arch Linux 上没有这条路径。

有arch 上的 Software_access_point wiki 页面其中可能包含一些有关如何创建热点的信息。我稍后会跟进，但如果有人有关于该错误的一些信息，那就太好了:)

我的网卡应该兼容：

$ iw list

Wiphy phy0
...
    Supported interface modes:
             * IBSS
             * managed
             * AP
             * AP/VLAN
             * monitor
             * P2P-client
             * P2P-GO
             * P2P-device

（需要AP）

$ lspci -k | grep -A 3 -i network

        Subsystem: Intel Corporation Dual Band Wireless-AC 7260
        Kernel driver in use: iwlwifi
        Kernel modules: iwlwifi

iwlwifi可以找到以下列表：

看起来确实支持AP。

第一次尝试

我尝试使用 热点

我创建了一个 python2.7 virtualenv 并安装了hotspotd==0.1.4，然后我安装了主机和dnsmasq。

$ sudo pacman -S hostapd
$ mkvirtualenv -p $(which python27) hotspot
$ workon hotspot
$ pip install hotspotd==0.1.4
$ sudo hotspotd -h

usage: hotspotd [-h] [-v] {start,stop,configure}

A small daemon to create a wifi hotspot on linux

positional arguments:
  {start,stop,configure}

optional arguments:
  -h, --help            show this help message and exit
  -v, --verbose


$ sudo hotspotd configure

我不知道为什么wlan0使用它，所以我尝试编辑/home/gableroux/.virtualenvs/hotspot/lib/python2.7/site-packages/hotspotd/run.conf，替换wlan0为我检测到的wlp61s0：

还是没有热点。我搜索了那个错误

nl80211：无法配置驱动程序模式

我找到了这个相关问题

我尝试了推荐的命令：

$ sudo iwconfig wlp61s0 mode master

Error for wireless request "Set Mode" (8B06) :
    SET failed on device wlp61s0 ; Invalid argument.

好吧好吧，听起来这可能是我的网卡。

在 MacOS 上这绝对更容易：/

编辑：自从我搬到 Fedora 后，我无法再重现这个问题，而且现在大部分事情都是开箱即用的。感谢您的帮助 ：）

答案1

问题可能出在您的主机名上。给出一些带有句点的名称。例如：“localhost.mine”或简单的“localhost”

您可以通过 GNOME 控制中心 -> 详细信息 -> 概述 -> 设置设备名称来设置主机名。

设置好主机名后，再次创建热点。

答案2

我用了create_ap。

pacman -S create_ap
sudo create_ap -m bridge wifi_interface ethernet_interface test_arch vinod123

注意：您将无法在主机上浏览互联网。也许我们应该使用NAT而不是bridge.我还没有尝试确认有关 NAT 的任何内容。

答案3

我通过nm-connection-editor手动创建 Wi-Fi 热点连接解决了这个错误。之后，“用作热点”按钮将按预期工作。
