只有一台设备可以连接到使用 wifi-ap 创建的接入点

0

我正在使用运行 Ubuntu Server 18.04 的 Dell Edge Gateway 3001 连接共享以太网（以及稍后的 GSM）连接的 IoT 设备。我已经使用wifi-ap snap来配置 AP，它似乎可以工作。不幸的是，一次只能连接一台设备。我正在尝试使用 Windows 笔记本和我的物联网设备 (ESP32)，两者都可以连接，但前提是当时没有连接其他设备。

这是我的 wifi-ap 配置

debug: true
dhcp.lease-time: 12h
dhcp.range-start: 192.168.7.2
dhcp.range-stop: 192.168.7.101
disabled: false
share.disabled: false
share.network-interface: eth0
wifi.address: 192.168.7.1
wifi.channel: 3
wifi.country-code: DE
wifi.hostapd-driver: nl80211
wifi.interface: wlan0
wifi.interface-mode: direct
wifi.netmask: 255.255.255.0
wifi.operation-mode: g
wifi.security: wpa2
wifi.security-passphrase: MyPassPhrase
wifi.ssid: DellGateway

有什么想法可能是这里的问题吗？

wifi不能直接在Ubuntu上工作

4

我的 PC 中有 Ubuntu 18.04 和 Windows 10。当 WiFi 在 Windows 上工作并且我将计算机重新启动到 Ubuntu 时，即使在 Ubuntu 中 WiFi 也可以。但是当计算机关闭并启动 Ubuntu 时，显然无法启动 WiFi。有人可以帮我直接在 Ubuntu 中提供 WiFi 吗？

我按照评论中的建议输入了 inxi -F ，结果如下：

此外，我打开“显示应用程序”并输入 wifi，他们说我“没有找到 wifi 适配器”。所以我重新启动并打开Windows，wifi开始工作。我再次重新启动并打开 Ubuntu，我有一个很好的 wifi。如果我把它关掉，我可以“不再连接，因为”没有找到 wifi 适配器“。有人可以解释我如何安装正确的 wifi 适配器。我在这里看到了很多帖子和 Ubuntu 文档，不知道是什么是正确的程序。

内核版本是 Linux 5.3.0-28-generic 我知道我需要一些与 Card-2 一致的 WiFi 适配器：英特尔无线 8265 / 8275 驱动程序：iwlwifi

按照@pilot6 的建议进行更新。我在 wifi 不工作时打字

创建家庭服务器作为 wifi 接入点和家庭路由器（Ubuntu 服务器 18.04）

1

我想建立一个有几个职责的家庭服务器

用于本地网络的无线 AP
用于各种设备（HTPC、网络打印机等）本地网络的以太网交换机
家庭防火墙和互联网网关
通用文件服务器等（与此问题无关）

我有一台带有 4 端口以太网卡的机器，以及主板上的两个以太网端口。我已插入支持 AP 模式的 USB 无线适配器。

root@dagda:~# ifconfig -a | grep flags
enp3s0f0: flags=4098<BROADCAST,MULTICAST>  mtu 1500

我的光纤调制解调器通过以太网连接，以太网具有调制解调器所在位置的enp7s0静态 IP 地址，通过 netplan 设置10.0.0.210.0.0.1

root@dagda~# cat /etc/netplan/01-netcfg.yaml
# This file describes the network interfaces available on your system
# For more information, see netplan(5).
network:

  renderer: networkd

      nameservers:
        addresses: [89.19.64.164, 89.19.64.36]

无线网卡能够接入点模式

root@dagda:~# iw list | grep -A 5 "Supported interface modes"
    Supported interface modes:
         * IBSS
         * managed
         * AP
         * P2P-client
         * P2P-GO

而且我已经成功地直接通过无线接口设置了 DNS 和 DHCP，所以我知道所有这些工作，但我想做的是为本地网络端设置一个 IP 地址。我想我应该能够桥接所有本地接口（以太网和 wifi）然后为桥分配一个静态 IP 地址并在桥上运行 dnsmasq 为所有本地设备提供 DNS 和 DHCP，无论它们如何连接，见下图

                         | --------------------------------- |

当我尝试创建桥梁时，我的问题就出现了

root@dagda:~# brctl addbr br0

                            enp4s0f1
root@dagda:~# brctl addif br0 wlx24050ff70bf6
can't add wlx24050ff70bf6 to bridge br0: Operation not supported

我试图找出为什么会发生这种情况，并在超级用户上遇到了这个问题，其中一个答案声称您无法桥接 wifi 和以太网，但奇怪的是，如果我在 netplan 中设置了网桥（下面的配置），我可以将wifi接口添加到网桥，但是通过我的手机连接到wifi声称它是一个WEP网络，尽管我在hostpad.conf中的设置明确只允许WPA2。不幸的是，我现在无法重现这一点。

我希望我的服务器有一个内部/本地 IP 地址，192.168.0.1无论哪个接口流量进入。我怎样才能做到这一点？

如何将 Ubuntu 设置为无线接入点？

26

如何设置我的 WiFi 以用作 Ubuntu Server 上的无线接入点？

我有一个本地 Ubuntu 服务器，它有一个无线网卡 (802.11a/b/g/n)，我真的想将它设置为 802.11n 接入点，因为我的普通接入点不支持 N。

它也需要作为交换机工作，以便我可以连接并通过 DHPC。

编辑：我不认为网络管理器是一个好的解决方案，因为它依赖于很多 X11 包，我不希望在服务器上使用它。

只有一台设备可以连接到使用 wifi-ap 创建的接入点

wifi不能直接在Ubuntu上工作

创建家庭服务器作为 wifi 接入点和家庭路由器（Ubuntu 服务器 18.04）

切换 WLAN 热点 Gnome 任务栏

OURLINK USB Wireless 的设置停止工作

如何将 Ubuntu 设置为无线接入点？

如何运行 .sh 脚本？

如何安装 .tar.gz（或 .tar.bz2）文件？

如何列出所有已安装的软件包

无法锁定管理目录 (/var/lib/dpkg/) 是另一个进程在使用它吗？
