AP 1200 Radio Interface resets


I have problems with a Cisco Aironet Access Point 1200 series (AIR-AP1231G-A-K9). This one presents connectivity problems since it shows resets on Fast Ethernet and radio interfaces. Now, already the physical level of the network is being checked with regard to the Fast Ethernet interface. But why are there resets in the radio interface? What can cause them?

Following the AP information:

Re: AP 1200 Radio Interface resets

I have a few questions to further deal with this issue.

- Is this a new installed AP1200? Is it the first time that customer is trying to connect through

this AP1200?

- Do you have another AP1200 with same software, which is working fine?

- Can you send me a ?show tech? and ?show logg? from the AP1200 with problem?

Also, refer the following document for any help.
