Ubuntu 13.10 互联网问题 - 12.04 LTS 也存在此问题

刚刚在新版本上安装了 13.10,遇到了一些问题。主要问题与互联网有关。我的主板内置有 realtek 以太网适配器,虽然可以连接,但无法获取 IP 地址,也无法 ping 路由器。

其次,我的 wifi 适配器(TP-link WDN4800)可以看到无线网络,但在连接提示输入密码时,它实际上从未连接。

我可以用有线和无线的方式从家里的其他机器连接到路由器,并且我尝试过手动分配 IP 地址以防出现此问题。我还尝试了此处建议的修复方法:http://www.linux-hardware-guide.com/ca/2012-11-01-tp-link-tl-wdn4800-wireless-n-dual-band-pcie-450mbps没有运气。

目前我通过我的iPhone(USB)连接到WIFI。

非常感谢您的帮助。一旦 Ubuntu 开始工作,我就很喜欢它,但事实证明,设置它是一件非常痛苦的事情。

编辑:也尝试了 12.04 LTS - 这里也存在这两个问题。

编辑 2-运行dmesg | grep -E 'cfg|ath|wlan'得到:

有什么想法吗?这看起来像是硬件问题。
