无法连接到无线接入点：关联超时

Question

我正在尝试使用 VersaLink 327W 作为无线范围扩展器和 AP来扩展我的无线覆盖范围。

我按照说明操作：

1. 禁用 DSL。
2. 使用 WEP 密钥启用无线访问（设备不支持 WPA 和 WPA2）。
3. 禁用 DHCP。
4. 将 IP 地址设置为192.168.7.2（因为要通过以太网连接的主路由器是192.168.7.1）。

唉，我无法从 linux 机器通过 WiFi 连接到设备：

kernel: [run timestamp] wlan0: authenticated0
kernel: [run timestamp] iwlwifi 0000:03:00.0 wlan0: disabling HT/VHT due to WEP/TKIP use
kernel: [run timestamp] iwlwifi 0000:03:00.0 wlan0: disabling HT as WMM/QoS is not supported by the AP
kernel: [run timestamp] iwlwifi 0000:03:00.0 wlan0: disabling VHT as WMM/QoS is not supported by the AP
kernel: [run timestamp] wlan0: associate with <<6*hex>> (try 1/3)
NetworkManager[pid]: <info>  [wall timestamp] device (wlan0): supplicant interface state: scanning -> authenticating
NetworkManager[pid]: <info>  [wall timestamp] device (wlan0): supplicant interface state: authenticating -> associating
kernel: [run timestamp] wlan0: associate with <<6*hex>> (try 2/3)
kernel: [run timestamp] wlan0: associate with <<6*hex>> (try 3/3)
kernel: [run timestamp] wlan0: association with <<6*hex>> timed out

即，身份验证有效，但关联（无论是什么）无效。

这不太可能是 linux 的问题，因为我也无法从 Mac 和 Android 手机连接。

那么，我现在能做什么？

谢谢。

附注。@Twisty 要求的其他信息：

我设置了localhostIP /etc/hosts，然后

# service network-manager restart

并观察这一点：

请注意，这ifconfig似乎忽略了我的设置。

我今天有一个非常相似的问题。为我修复的是更改 NetworkManager 的配置：

1. 编辑文件/etc/NetworkManager/NetworkManager.conf（位置可能会有所不同，具体取决于您的发行版）

2. 将以下行添加到该文件中：

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

3. 重新启动 NetworkManager 服务： sudo service network-manager restart
