请问下,我现在有两个无线AP1142的,但是每隔两到三天就会重新启动,这个大概是什么问题呢?其他的AP都没有问题。

1. 建议先查看WLC上面有没有AP crash log; GUI > MANAGEMENT > TECH SUPPORT > AP Crash Log
2. 如果有,可根据crash log去CCO上面查看是否是已知软件BUG。
3. 如果WLC上面没有AP crash log, 则建议在AP上面抓取show tech / show log , 开个TAC case进行下一步排查。

简单来说,只要AP和WLC之间网络可达,AP就可以注册到WLC。不论是在公网还是企业内部。

1.首先AP要与WLC关联上,必须保证他们的路由是可达的。
2.二层环境下,AP是通过广播发出请求信息的。
3.三层环境下,广播是无法泛洪的,只能通过DNS或option 43 指定 WLC
4.最后也可以配置LAP :
capwap ap ip add ***
capwap ap ip default-gateway ***
capwap ap controller ip add ***
实现

@C1whaitao 说得不错。
如果AP走ADSL出去,可以直接在AP上面指定WLC management ip NAT对应的公网IP。
另外,在WLC侧做NAT的时候,请注意以下两点:
1. Note: Select the Enable NAT Address check box and enter the external NAT IP address if you want to be able to deploy your Cisco 5500 Series Controller behind a router or other gateway device that is using one-to-one mapping network address translation (NAT). NAT allows a device, such as a router, to act as an agent between the Internet (public) and a local network (private). In this case, it maps the controller's intranet IP addresses to a corresponding external address. The controller's dynamic AP-manager interface must be configured with the external NAT IP address so that the controller can send the correct IP address in the Discovery Response.
2. Note: With CAPWAP, WLC behind NAT is not supported with the 4400 series, 2100 series Wireless LAN Controllers and the WiSM.

建议好好理解AP注册的整个过程,推荐阅读CCO文档:
Lightweight AP (LAP) Registration to a Wireless LAN Controller (WLC)
如果在AP注册的过程遇到问题,可以参阅以下文档:
Troubleshoot a Lightweight Access Point Not Joining a Wireless LAN Controller
"AP fails to join controller" - Lightweight Access Point (LAP) fails to join Wireless LAN controller (WLC)
