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。
