与Centrino Wireless-N 1000的无线连接持续时间不会超过20秒

我的笔记本电脑是联想Sl510。 它将询问我的网络密钥,输入后,它会在大约20秒后丢失,然后再次询问密钥,并继续执行此操作。 在今天尝试12.04之前,我从未遇到任何连接问题。

我该如何解决这个问题?

我在联想x121e笔记本电脑上使用相同的无线设备,但也有类似的问题。

我不得不禁用无线’n’网络。 这解决了我的问题。

试试看:

 echo 'options iwlagn 11n_disable=1' | sudo tee /etc/modprobe.d/iwlagn.conf >/dev/null 

然后重新启动计算机。 希望这可以帮助… ;)

来源: Linux iwlagn问题

尝试以下,为我工作:

在终端类型

 sudo iwconfig wlan0 power off 

就我而言,电源管理被打破了。 如果它工作,只需执行以下操作来修复启动时的问题

 sudo nano /etc/rc.local 

并在(!)“exit0”上粘贴“iwconfig wlan0 power off”。 保存文件并重新启动。

我希望这有帮助。

我想你可能有一个bug,但我不能确定。 我有一个带有这种无线网卡的Thinkpad X220,我看到了这个问题:

如果您可以在评论#72中遵循Joseph的建议,请尝试该内核,并报告错误报告,如果删除工作,它将真正帮助修复所有Centrino 1000用户。

(你可能也有一个单独的问题,但这是一个合理的教育猜测,尝试内核然后如果我错了就删除它不会有害)

刚刚在我的dell xps15上遇到了同样的问题,尝试了断电技巧并且它不起作用,这对我有用 – 至少似乎是在工作,目前为止10分钟没有断开连接:

(以下说明是近似的,因为我有意大利语安装,我不能保证菜单项与我提到的完全相同,如果没有尝试找到最接近的选项)右键单击任务栏中的无线图标,转到修改连接,选择无线选项卡,然后选择您的无线连接(由您的SSID标识),然后单击修改。 打开Wireless Security选项卡,在那里输入密钥,然后单击save。 显然这会让它变得坚持,或者至少对我有用。

祝好运 :)

我有类似的问题,但使用不同的卡/芯片,intel ipw2100。

更改BIOS中的IRQ对我有帮助。

文章“在ubuntu 11.04,11.10,12.04精确穿山甲和LinuxMint12中使用wifi时解决慢速联系”有一些很好的见解。 它列出了您可能想要阅读的其他解决方案。
