Starting last Thursday 5 or 6 or our largers sites (30-60 205 aps and 800-1000 clients) started randomply giving out APIPA addresses. These sites have been up for about 9 months with no issues. Rebooting the AP's fixes the issues for a few days then it starts up again.
I have Airwave set up running 8.2.3.1 with about 900 aps and they are all running 6.5.1.0-4.3.1.0_57768. The smaller sites with 10-20 aps have had no issues so far.
We have 2 vlans that they get dhcp from a dhcp server onsite at each location and there is lots of IP's available in the pool.
I read about this a few times on various foumns but no one ever posts a fix so i am at a loss.
Thanks in advance for any help you guys can provide.
