While monitoring our AP420s in ProCurve Manager, I've noticed that some of them on occasion will not show any radio information. The icons for viewing clients, neighbors, etc. are greyed out. The access points show a status of "good" and can be pinged, but they cannot be accessed in any way via telnet or the web interface. When this happens, connection to the network for clients is non-existent even though they can see the SSID and show good signal strength. To solve the issue we have to cycle the power on the access point.
This has happened with AP's running 2.2.3 and 2.1.7 software versions now.
Any clues?
Thanks,
Rick
