无线互联网TP-Link TL-WN821N速度极慢

在我从11.04更新到11.10之后,互联网几乎无法运行。 加载网页可能需要几分钟,即使它首先工作也是如此。 我现在知道这是一个错误,如果它是我应该如何更新? 互联网不起作用,只是崩溃! 请帮忙。

我在Thinkpad X1上遇到了类似的问题。 禁用无线N解决了这个问题。 你使用什么无线驱动程序/内核模块?

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

在未来,我建议购买Linux中完全支持的硬件,以解决这些问题: http : //www.thinkpenguin.com/catalog/networking-modems

其次,你列出了你的PCI卡,显然你有一个USB wifi卡。

但是,如果你看这里,有人似乎已经让你的卡工作在11.10 http://myubuntunotes.wordpress.com/2011/03/03/hello-world/
