文章标签:WIFI  WIF  

问题:

这是 13.04的问题,无线局域网有问题。 Ubuntu永远不会连接到网络。 我所有的其他设备都能正常工作。

计算机检测到网络并弹出wifi密码对话框。 输入正确的密码,单击确定,然后尝试连接几秒钟,然后再次请求密码。 我正在使用一个新的d 链路无线N 150微型USB适配器,可以在 Windows 下工作,连接到同一。

我搜索谷歌几个小时没有找到答案,也许这里有人可以帮助?

回答 1:

你可以尝试关闭很快断开卡连接的无线省电:


sudo iw wlan0 set power_save off



编辑:更多建议。

从发送的输出中可以看出,ipv6无法连接

Edit> 选择你的网络then然后单击 Edit> IPV6> 设置方法""

我看到其他与证书有问题的线程: 无线网络中的认证


 sudo nano/etc/NetworkManager/system-connections/YOUR-NETWORK-NAME



并注释掉( 在前面放一个 # ) system-ca-cert=true

可能是你的usb适配器的固件问题? 你可以尝试通过以太网电缆连接,并通过软件更新程序进行更新。

记住最后的事情,删除当前的连接并重新开始。

让我们知道它是如何运行


回答 2:

我看到dhclient无法从路由器中检索 IP。 至少 IPv6.因此尝试将IPv6设置为"忽略"和/或者使用 IPv6/ipv4启用/禁用。 所有这些都没有帮助我( 我有相同的记录)。 我手动设置了 IPv4.首先设置随机 IP,然后连接到路由器。 这里我没有互联网,但我连接到路由器。 然后,我将ed网络查找路由器 IP: nmap 192.168.0.0/23,然后将路由器IP设置为网关。

这不是所有情况下的解决方案,但它今晚帮助我连接酒店免费 Wi-Fi。 我还得设置 DNS。 我使用谷歌 public dns,但你可以设置任何其他。
