全新安装后无线连接缓慢/不一致Ubuntu 14.04(Realtek RTL8188EE)

我使用开发版本运行Ubuntu 14.04一个多月没有问题。 然后我在官方发布日期升级并开始问题。 我感到沮丧并做了全新的安装,但仍有同样的问题。

我可以很好地连接到我的无线网络,但我的连接强度和速度是非常零星的。 它似乎从非常缓慢到正常,很快就像波浪一样。 我的路由器下面的ping结果可能会说明这一点。

Ping路由器,正常到低负载:

我的笔记本电脑是东芝Satellite S55-A5294。

将我的内核升级到3.14.1和3.14.2(目前正在使用)后,我的无线现在有时可用(这让我很开心)。

我在大约70%的时间内丢失了0%的数据包,丢失了1到100%的其他30%。

重新连接到我的无线网络是我到目前为止找到的唯一解决方案,但它并不总能解决问题。

我不确定这些日志是否是此问题的原因的任何迹象,或只是通知它正在发生。

任何想法将不胜感激。

这是我一直遇到的问题。 要解决此问题,您需要手动升级内核。 我亲自升级到3.14.1。

以下是手动升级内核的指南: 如何在没有任何Distro-upgrade的情况下将内核更新到最新的主线版本?

编辑:我也没有意识到我发布这个,但我有与你相同的无线网卡,所以这应该工作。 我无法保证任何其他卡。

我已经解决了将路由器更改为固定通道的问题(在我的情况下为3)。

我尝试了很多改变我的驱动程序,更新我的内核,但意识到我的范围内有很多无线网络,这可能与我的有冲突,因为我只在我使用的三个网络之一上遇到此问题而在另外两个它没有问题。

这是在Ubuntu 14.04 64,笔记本电脑dell vostro 5470上。
