WE have 5 AP250's all running 8.2r3. One AP is having issues with a specific set of newer OSX clients (any USB-C macbook). Windows devices, older macbooks , iphones/android devices all seem unaffected. affected clients are dropping 50%-50% of packets during a ping test. WHen the client connects to another AP in our center, no issues. THe AP250's are less than a year old, bought through Dell.

I have experienced 5-10% ping loss with OSX macs, but this was due to WIPS. When WIPS was diluted to not scan for wireless rogues, the ping tests achieved 100% success.
