WLAN 问题：(wlan0/wireless)：关联时间过长，激活失败

  • 772

我有一台笔记本电脑

  • 英特尔公司无线 3160（修订版 83）；固件版本 25.17.12.0

我看到 WLAN，我可以输入我的密码。尽管重复输入密码并目视检查密码，但仍未建立连接。

路由器上没有 MAC 过滤，并且允许所有（新）设备。

在使用 Ubuntu 安装的固件测试网络之前，我已经从Linux Wireless安装了固件。

我该如何解决这个问题？

我用我的智能手机创建了一个热点。同样的问题。

IPv6 禁用，同样的问题

$ cat /proc/sys/net/ipv6/conf/all/disable_ipv6
1

$ ip a | grep inet6
*no output*

  1. 我有一个类似的问题：我的 AP（运行 OpenWRT - 与其他 AP 的问题较少）很少出现在扫描中，并且关联尝试大部分时间都失败了，“关联时间太长，激活失败”......“ssid-not-found “，尽管在几分钟/尝试后它通常确实连接了。我有一个 Intel 8265 wifi 卡（虽然我不知道设备是否重要）。

    由于我不明白 NetworkManager 的 MAC 地址随机化功能（默认情况下用于扫描）导致问题的原因。要修复它，请创建一个/etc/NetworkManager/conf.d/30-mac-randomization.conf禁用该功能的文件：

    [device-mac-randomization]
wifi.scan-rand-mac-address=no

    ... 其次是sudo systemctl restart NetworkManager

    wifi.scan-rand-mac-address=no更新：在使用我的 AP运行几天后，有时仍需要多次扫描才能购买。但至少联想总是有效的。

    从您的无线调试中，我会：

    • 在路由器上停用 IPV6（或更新路由器的固件）
    • 停用路由器上的 802.11N（或更新路由器的固件）
