We have an environment with 36 R510 APs spread among 12 floors with 2 ZD1200's on the back end. We notice on a daily basis that random set of Wifi users cannot browse the internet or get disconnected in the middle of a video call even though they have full bars for Wifi. This is an issue because the building is 100% wireless. We have turned off DFS channels, and tweaked power levels accordingly to minimize overlap. It seems that only Apple users are effected. Are there any known issues with Ruckus and Apple devices?
