AP，配置问题

        上午发了一个，没解释清楚，该AP型号为WA2620i-AGN，模式为fit, AC控制，之前一直正常使用，昨天突然掉线，连接不上AC，获取不到地址，设备一直红灯闪烁。先排除了网线问题，后来电脑连接启动日志如下：

BootWare Validating... Press Ctrl+B to enter extended boot menu... Starting to get the main application file--flash:/wa2600a_fit.bin!.......... ............................................................................ ............................ The main application file is self-decompressing............................. ............................................................................ ............................................................................ ............................................................................ ............................................................................ ............................................................................ ............................................................................ ............................................................................ ............................................................................ ............................................................................ ............................................................................ ............................................................................ ..............................................................Done! System application is starting... This device have lost some radio card!!!Please return for repair!!! Startup configuration file does not exist. User interface con0 is available. 

翻译意思应该是什么丢失，请返修，该设备刚刚过了保修期了，我自己刷了下固件，还是报这个错误。
