420WW Access Points dropping off network

[Paul Cross_2]

Hi there,

I have spent the summer installing 27 HP 420 wireless points (v2.1) throughout the college where I work. They're all set up with dynamic vlans, 802.1x tkip+aes wpa+wpa2 with IAS server and a mixture of PoE and regular Power supplies. I thought all was working well.

However I have noticed that several APs have dropped of the network (wireless broadcast and serial connection is fine) and the only way to get to work again is to unlplug, wait 10 seconds and retry. Our network is HP procurve backbone and edge.

Yesterday I set up a scheduled ping (twice daily) of all 27 to spot how often this happens. This morning 3 of the devices were off the network, and this afternoon a further 3 had also fallen!

Are there any known problems like this with the 420s or do I have some rogue user breaking all my access points? (I can't check the logs without resarting the wap and therefore losing them...)

The Access points were all on ok this morning, but one has just disconnected from the network (first time for this one) I've checked the logs using the CLI and show event-log, but there doesn't seem to be anything wrong.

Well, I've rolled back the firmware version to 2.041 and everything has been stable. Unfortunately I lose some of the good new features of the latest firmware but at least it is stable!

So there's a firmware ugrade - 2.1.2 - which seems to fix it. Thanks for all your help.
