无线问题 ubuntu 12.04 edubuntu

我尝试从普通的 ubuntu 12.04 升级到 edubuntu 12.04,因为我的无线连接出现了一些问题。edubuntu 中仍然出现问题,wifi 符号显示我收到了信号,但当我上网时,突然在一段随机的时间后,我无法再下载/浏览,但 wifi 符号仍然显示我收到了信号。

当我安装 Windows XP SP3 时也出现了这个问题,我以为是驱动程序有问题,但我从未真正找到解决方案。

我现在有点受够了,因为在过去的几天里,我一直在尝试一切办法让我的电脑在 Windows 以外的其他操作系统下重新工作,但到目前为止还没有成功。

我希望有人能帮助我,这样我最终就能再次使用我的笔记本电脑(戴尔 Latitude d620)。

提前致谢!

答案1

由于问题出现在两个不同版本的 Ubuntu 以及 Windows XP 上,我怀疑是路由器设置的问题。无线是如何配置的?WPA2 和什么加密?TKIP 还是 AES?首选 AES。如果可能,请不要使用混合模式 WPA 和 WPA2。它能达到 N 速度吗?您是否尝试过将无线重置为仅 B 和 G?它能同时支持 2.4 Ghz 和 5 Ghz 频段吗?您是否尝试过禁用 5 Ghz 频段?
