We have a large wireless implementation with a central controller managing APs in remote sites. Generally, the APs and clients are very stable. However, a couple sites occasionally have much higher than average latency (over 300ms). During these high latency periods, Mac clients can experience frequent disconnects, although the Windows pcs are fine and the APs are not dropping.
Recognizing that the main issue is the poor WAN connection, what can we do to improve the stability of the Mac clients?
