我的局域网上有几台装有各种操作系统的计算机,其中一台装有 Ubuntu 13.04 64 位,是唯一无法自动配置 IPv6 地址的机器。rdisc6 在这台机器上超时,而在我的所有其他 Linux 机器上都成功了。发生了什么?
在 IPv6 不起作用的盒子上,它有一个 Realtek 8187B wifi 卡:
[18:50:19] domitille:~
alisonc $ rdisc6 wlan1

Timed out.

No response.

我使用华硕 RT-N16 作为 IPv6 路由器,并配有 Hurricane Electric 隧道。连接 WLAN 的计算机连接到配置为无线 AP 的 Netgear WNDR3700v3。
如能提供关于在 domitille 的配置中应寻找什么的任何指示,我将不胜感激。

好吧,我通过升级到 802.11n usb 无线网卡(华硕 USB-N10)解决了 IPv6 问题。现在它像这样:

我觉得很奇怪,将无线网卡从 802.11g 换成 802.11n 就能解决这个问题,但事实确实如此。
