无线问题ubuntu 12.04 edubuntu

Question

我试图从普通的ubuntu12.04转到edubuntu12.04，因为我的无线连接有一些问题。问题仍然发生在edubuntu，wifi符号说我得到了信号，但是当我上网时，在随机的一段时间之后，我突然不能下载/浏览了，但是wifi符号仍然说我收到了一个信号。

当我安装了Windows并安装了SP3时，也出现了这个问题，我认为这是一个糟糕的驱动程序，但我从未真正找到解决方案。

我有点厌倦了自动取款机，因为在过去的几天里，我一直在尽我所能让我的电脑在与Windows不同的操作系统下重新工作，到目前为止还没有成功。

我希望有人能帮我，所以我终于能够再次使用我的笔记本电脑(戴尔纬度d620)。

提前谢谢！

Answer 1

由于这个问题发生在Ubuntu的两个不同版本以及Windows中，所以我怀疑路由器的设置。无线是如何配置的？WPA2和什么加密？TKIP还是AES？最好是AES。如果可能，不要使用混合模式的WPA和WPA2.它能达到N个速度吗？你试过将无线设备重新设置为B和G吗？它能同时拥有2.4 Ghz和5 Ghz频段吗？你试过禁用5 Ghz频段吗？
