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

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

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

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!
