我的手机上有一个刚刚设置的无线接入点。我的手机是三星 Galaxy S2，由 ATT Wireless 提供。当我第一次设置时，网络管理器识别出该接入点，我能够连接。
然后，一两天后，连接只能维持大约一分钟。我查阅了以下链接，其中的任何建议都对我的情况没有任何影响：
http://www.askubuntu.com/questions/117969/wifi-hotspot-disconnected-after-some-time （这个答案里根本没有相关信息。）
13.10 上无法连接 VPN pptp （这是一个 VPN）
Wifi 连接问题 （设置 sudo iw wlan0 set power_save off 没有效果）
我可以保持与其他 wifi 路由器、家庭作业等的连接，只是不能保持与手机的连接。
我正在运行以下系统：
Linux 3.11.0-19-generic #33-Ubuntu SMP
Description: Ubuntu 13.10
Release: 13.10
Codename: saucy
驱动程序（由 lspci 提供）是：
Network controller: Intel Corporation Wireless 3160 (rev 83)
一旦我失去连接，SSID 扫描就无法再看到该设备。我必须重新启动 wpa_supplicant 才能再次看到它并连接到它。
查看 /var/log/syslog 可查看正在发生的一些片段：
初始成功连接：

对于“CTRL-EVENT-DISCONNECTED bssid=20:64:32:3a:91:85 Reason=4”，我找不到解释 Reason=4 含义的资源。
我们确实看到，在后续重试中，链接超时，并显示 CTRL-EVENT-DISCONNECTED bssid=00:00:00:00:00:00 Reason=3
这是有道理的，因为 wpa_supplicant 不再能找到该设备。
我可以通过运行以下命令重复此过程：
ps -ef | grep wpa
kill -9 (the pid of wpa_supplicant)
向 wpa_supplicant 添加详细日志记录显示以下内容：

因此无论 EAPOL 是什么，它都不再具有身份验证功能。
简单回顾一下：
- 无法连接到移动无线（通过 ATT 连接三星 Galaxy S2）超过 1-5 分钟
- 可以毫无问题地连接到其他无线接入点。
- 日志表明设备无法验证且超时。
其他论坛帖子指出要么是内核问题，要么是设备驱动程序问题。我的情况很混乱，因为我可以连接到 wifi 热点。
哦，我不太确定是不是手机的问题。我还没有在其他设备上测试过。我的直觉告诉我，问题不在于手机。
感谢您花时间帮助我。刚刚从 Debian Wheezy 迁移到 Ubuntu，所以……这根本没用，但这是我的第一篇 Ask Ubuntu 帖子。
更新：我已从手机中删除了此机器的 MAC 地址，并且只是使用 WPA2 进行身份验证。显然，这没有任何作用。
日志似乎表明该设备不再认可连接的真实性。在尝试隔离 wpa_supplicant 时，我从终端调用了 wpa_supplicant，传入了驱动程序和 ssid，但这与运行自己版本的 wpa_supplicant 的 NetworkManager 混在一起，显然它们不能很好地配合。
另一个罪魁祸首可能是 dnsmasq，因为它看起来正在向我的手机查询 dns 条目，而且这两者可能交互得不是很好“我想要一个 dns 条目。当然。我想要一个 dns 条目。等一下，我两分钟前刚刚给了你一个。”
每日问题：当提供背景和日志以及历史记录和日志的完善问题被忽视时，您难道不喜欢它吗？因此，当连接被束缚时，连接是稳定和连续的。那么信号出了问题。也许是驱动程序不好？不确定，因为这个问题相当荒唐。
答案1
显然，realtek 无线设备驱动程序存在内核错误。我在 Ubuntu 14.04 上遇到了同样的问题，我的连接断开了。我准备恢复到较旧的内核版本，看看是否能解决我的问题。希望你能找到解决问题的帮助。Wildman 和我正在线程上解决我的问题使用 UBUNTU 14.04 (Realtek RTL8188) 时 Wifi 断开并重新连接，我们记录了我们一路上的步骤，如果您的问题与我的问题足够相似，也许您可以尝试我们尝试过的一些方法并找到解决方案。
