1，接入AP型号在AC支持列表

2，排除AC无授权问题

3，排除AP，AC通信问题

解决方案1：（失败）

format flash:/  让格式化APflash，让AP自动从AC下载wa2600a.ipe

AP同步完成之后还是会提示

Decompressing file wa2600a-boot.bin to flash:/wa2600a-boot.bin......................Done. 

Decompressing file wa2600a-system.bin to flash:/wa2600a-system.bin....................................

解决方案2：（失败）

从AC手下下载wa2600a.ipe文件，然后tftp到AP的flash手动同步.

AP同步完成之后还是会提示

Decompressing file wa2600a-boot.bin to flash:/wa2600a-boot.bin......................Done. 

Decompressing file wa2600a-system.bin to flash:/wa2600a-system.bin....................................
