在英文社区查到个类似的情况,有可能是bug,但是bug中的一个条件是domain是-T的,—H的AP有没有这种问题不太好说。

可以尝试手动刷一个其他版本试试能否注册。换版本不好使的话建议直接开case处理

请问有更换版本的操作步骤吗?

进到CLI里面:archive download-sw /reload tftp://x.x.x.x/ap3g3-k9w8-tar.153-3.xxxx.tar 即可,传输完成之后自动重启,重启完成后show version确认版本

你好请问此类问题有所解决吗。我有个AP AIR-AP1832I-H-K9也是此类问题想请教解决办法。

硬件坏了,找人维修好了

您好,请问这类ap如何更新版本尝试一下。
