Aironet Management Interface down and cannot ping

Hello,

I am getting intermittent problems on most of my Cisco Aironet 1242 and 1231 access points for a few years now. They are a mixture of light weight and autonomous. Randomly they will stop replying to ping request, which means you cannot telnet or connect to the web interface (I believe this is the management interface?).  The access point is still works fine, and if you run the ‘show cdp neighbours’ command from the switch they are connected to, it does show the access point is connected.  The only way I have found to resolve the issue is to reboot the access point, but finding time to do this is often difficult.  Once rebooted it will go days/months/years before the issue re-occurs.  Does anyone have any idea what might cause this or how I can re-enable the management interface without rebooting the switch – can I connect with console cable and run a command? 

Thanks in advance.
