無法新增連線：(2) 如果未給予 AP 路徑，則需要具有有效 SSID 的「無線」設置

我目前正在嘗試從 arch-linux 共享無線網路。網路設定中有一個按鈕可以讓我執行此操作：

網路設定“用作熱點...”

我點擊了“打開”按鈕，因為這正是我正在尋找的！

Wi-Fi 熱點彈出視窗打開

但在終端機中使用以下命令：

$ sudo journalctl -xef

我仍在閱讀這裡和那裡的一些文檔，但除了此處某些原始程式碼中的確切錯誤訊息之外，我還沒有找到與此錯誤有關的任何內容：

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

一位朋友在 Fedora 上進行了測試，它開箱即用，他ESSID在這裡找到了與他創建的 wifi 相匹配的設定：

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

但我在 Arch Linux 上沒有這條路徑。

有arch 上的 Software_access_point wiki 頁面其中可能包含一些有關如何建立熱點的資訊。我稍後會跟進，但如果有人有關於該錯誤的一些信息，那就太好了:)

我的網路卡應該可以相容：

$ 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

3d:00.0 Network controller: Intel Corporation Wireless 7260 (rev 6b)
        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:

| Driver                                             | Manufacturer        | cfg80211 | AP      | IBSS | mesh | monitor | PHY modes  | Buses                    |
|----------------------------------------------------|---------------------|----------|---------|------|------|---------|------------|--------------------------|
| iwlwifi                                            | Intel               | yes      | yes (6) | yes  | no   | yes     | A/B/G/N/AC | PCI-E                    |

看起來確實支援AP。

第一次嘗試

我嘗試使用 熱點

我創建了一個 python2.7 virtualenv 並安裝了hotspotd==0.1.4，然後我安裝了主機和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

我不知道為什麼wlan0使用它，所以我嘗試編輯/home/gableroux/.virtualenvs/hotspot/lib/python2.7/site-packages/hotspotd/run.conf，替換wlan0為我檢測到的wlp61s0：

還是沒有熱點。我搜尋了那個錯誤

nl80211：無法配置驅動程式模式

我找到了這個相關問題

我嘗試了推薦的命令：

$ sudo iwconfig wlp61s0 mode master

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

好吧好吧，聽起來這可能是我的網卡。

在 MacOS 上這絕對比較容易：/

編輯：自從我搬到 Fedora 後，我無法重現這個問題，而且現在大部分事情都是開箱即用的。感謝您的幫助 ：）

答案1

問題可能出在您的主機名稱。給出一些帶有句點的名稱。例如：“localhost.mine”或簡單的“localhost”

您可以透過 GNOME 控制中心 -> 詳細資訊 -> 概述 -> 設定裝置名稱來設定主機名稱。

設定好主機名稱後，再次建立熱點。

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：您將無法在主機上瀏覽網際網路。也許我們應該使用NAT而不是bridge.我還沒有嘗試確認有關 NAT 的任何內容。

答案3

我透過nm-connection-editor手動建立 Wi-Fi 熱點連線解決了這個錯誤。之後，“用作熱點”按鈕將按預期工作。
