WLC 2504+AIR-CAP2602I-C-K9 AP无线网络2.4G网卡经常掉线

[dami.zhang]

你们好！
我公司采用的WLC 2504和AIR-CAP2602I-C-K9 AP组建的无线网络，后来发现购买的DELL的笔记本，无线网卡是2.G的，比如（Intel Wireless-N 7260），这些笔记本在使用无线的时候，几乎都是经常掉线，就算是笔记本放在AP旁边都会掉线。只能购买支持双频的外置无线网卡插在笔记本上用。我和DELL公司联系过，也请他们的工程师拿走笔记本做过测试，他们说没问题，也解释不了这个原因。我想在这里提出这个问题，是否有人能给给出解答，非常感谢！

下面是debug了一次掉线的过程
*pemReceiveTask: Feb 27 02:09:46.785: 14:e6:e4:1c:b3:26 Pushing IPv6: ...

从LOG上看，网卡的IP地址会在172.16.1.* 和 172.16.2.* 间变化 , IPV6似乎有一点影响，试试关闭无线网卡上的IPV6功能试试。

麻烦你进入WLC的命令行模式，通过debug client ***(无线客户端网卡MAC) ，查看log 后获知故障的原因，再来解决吧。debug disable-all 关闭debug

radio固定下试试

无线是不是有干扰

Intel 7260 Drive 必須 upgrade至V17以後的版本。Drive v16會斷線

[llk1234]

是不是网卡驱动更新问题呢！

靠谱，这种问题应该先升级客户端驱动。明显不是AP，WLC问题

笔记本拿回家用家里的wifi就不掉线正常，应该不是网卡的问题，谢谢！
