使用 Centrino Wireless-N 1030 [Rainbow Peak] 后 wifi 速度变慢

从 kubuntu 13.04 升级到 13.10 后,我的 wifi 连接突然变得非常慢。到 www.google.nl 的 Ping 时间从 200 毫秒到 1500 毫秒不等。

当我连接以太网电缆时,它们会降到正常时间,例如 8 或 9 毫秒。有人遇到过同样的问题或知道我可以尝试的解决方案吗?在升级过程中,他们几次询问我是否要保留或替换某种配置文件。我不确定是哪个文件,但也许这与它有关。升级之前,有线和无线连接都运行正常。

答案1

做:

echo "options iwlwifi 11n_disable=1" | sudo tee /etc/modprobe.d/iwlwifi.conf
sudo modprobe -rfv iwldvm
sudo modprobe -rfv iwlwifi
sudo modprobe -v iwlwifi

进入网络管理器并更改无线设置以匹配屏幕截图。

无线设置无线设置

进入您的路由器并将 802.11bgn 更改为 802.11bg,然后保存设置并重新启动路由器和计算机。

让我们修改这个文件:sudo /etc/modprobe.d/iwlwifi.conf 更改

options iwlwifi 11n_disable=1

到:

options iwlwifi 11n_disable=1 iwlwifi bt_coex_active=0

答案2

当我更新到 14.04 时,我遇到了同样的问题。我尝试了所有方法,也尝试了这篇文章中的答案。过了一会儿,我想我会试试 LM,结果发现问题消失了,奇迹就在 linux-firmware 包中。LM 使用旧版本 1.127,而 Ubuntu 现在使用 1.127.7。将其恢复到此版本的最简单方法是:安装 Synaptic,找到此包,单击以标记它,按 Ctrl+E 并更改其版本。应用更改,问题解决。

答案3
