How can an AR router correctly connect to an ACS

1

1. Ensure that the AR router can ping the ACS successfully.
2. Ensure that the AR router is configured with the same URL as the ACS.
3. Run the undo cwmp enable command and then the cwmp enable command in the CWMP view of the AR router to trigger a session connection.
4. If no connection is established, the AR router and ACS may fail to exchange packets. Capture packets on the ACS to locate the packet exchange failure. After the packet exchange failure is rectified, perform step 3 again to trigger a session connection.

An AR cannot connect to an ACS
1. Ensure that the AR can ping the ACS successfully. 2. Ensure that the AR is configured with the same URL as the ACS. 3. Run the undo cwmp enable command and then run the cwmp enable command in the CWMP view of the AR to trigger a session connection. 4. If no connection is established, the AR and ACS may fail to exchange packets. Use a tool to obtain packets on the ACS to locate the packet exchange failure. After the packet exchange failure is rectified, perform step 3 again to trigger a session connection.

Can AC and AP functions of the AR router coexist
AR routers of which names contain W support both the Fat AP function and AC function. The two functions cannot coexist on the same router. You can run the set workmode wlan command to switch between Fat AP and AC functions.

How to connect the AR router to the HyperTerminal
When you log in to the device through the console port, you need to install the terminal access software on the local PC (such as SecureCRT software) and set parameters of the terminal simulation software.
