I've been fighting this on my own for about 2 months now and decided to ask for some help.
I have one particular portion of my network that complains they can set their watch by the network outage at 10am every morning.
I am obviously a skeptic. But, after watching some pings and connectivity of wifi devices, I notice that between 10 and 10:05 EVERY morning this particular wing drops or at least has pings over 3000ms. Some devices drop completely others just become so slow they can't do anything.
I ran through some other scenarios causing the issue and found that it is only happening to wireless clients, and only happening to clients connected to AP230s. This leads me to believe there is a wireless scan or some 'process' running on those devices at that time. I have tried to remove settings that I could find that point to channel scanning when clients are connected. I also have upgraded to the most recent OS for the AP230s. Today, Dec 28th, there was only 1 device connected at the school, and pings to that device dropped before they became 3300ms and then leveled off to above 500ms then came back to normal after 10:05. After this I reverted all the AP230s back to 6.5.8r code to see if that will work tomorrow.
Has anyone experienced anything like this? And more importantly, has it been fixed?
