TP-Link TL-WN821N 无线网络速度极慢

我从 11.04 更新到 11.10 后，互联网几乎无法使用。加载网页可能需要几分钟，即使它一开始就正常工作。我现在不知道这是否是一个错误，如果是，我该如何更新？互联网无法使用，只是崩溃了！请帮忙。

无线网卡：TP-Link TL-WN821N

答案1

我的 Thinkpad X1 也遇到过类似的问题。禁用无线 N 即可解决。您使用的是哪种无线驱动程序/内核模块？

#/etc/modprobe.d/_wlan.conf 
options iwlagn 11n_disable=1

答案2

将来，我建议购买完全受 Linux 支持的硬件以避免出现这些问题： http://www.thinkpenguin.com/catalog/networking-modems

其次，您列出了 PCI 卡，但显然您有一个 USB wifi 卡。

然而，如果你看看这里，似乎有人让你的卡在 11.10 中工作 http://myubuntunotes.wordpress.com/2011/03/03/hello-world/
