我遇到了一些严重的问题，当我启动我的 Ubuntu 笔记本电脑并连接到 WiFi 时，一些（不是全部）其他 Windows 笔记本电脑会失去与我们网络的连接。然后，当他们尝试重新连接时，他们会收到“Windows 无法连接到网络...”错误。路由器重新启动后，我没有连接我的 Ubuntu 笔记本电脑，它工作正常。当我连接时，大约 1 分钟后它们就会失去连接。
我有一台 TL-WR1043ND (TP-Link) 路由器，我的 Ubuntu 笔记本是 Acer Aspire V3-772G。使用 WPA2-PSK 安全，将路由器重置为出厂设置不起作用。没有 IP 冲突。（一切都通过 DHCP 进行，我没有静态 IP）
我不知道先去哪里问，但我认为这应该与我的 Ubuntu 安装有关，这就是我首先在这里询问的原因:)
谢谢
该lspci -nn | grep 0280命令将返回：

当 Windows 机器断开连接时（此屏幕截图是另一个 DHCP 请求，因为日志已被清除）每次他“重试”时，我都会在路由器日志中看到以下内容： http://screenshot.wouter0100.nl/1396474377232014021396474377.png 只有这 2 个条目，通常要多得多..
答案1
尝试从其他笔记本电脑克隆其中一个网卡的 MAC 地址，并在 Ubuntu 中将其用于 eth0 / dhcp 电缆连接。将 mac 地址从运行 Windows 的计算机克隆到运行 Ubuntu 的计算机后，看看运行 Windows 的其他笔记本电脑是否遇到同样的问题。
我猜是您的 ISP 不允许您将 Internet 连接用于 1-2 台以上的计算机，这就是您收到这些错误的原因。也许他们想让您额外付费才能使用同一连接使用更多计算机……？
