The title says it all. We have purchased a pack of three Cisco 240AC wireless access points model: CBW240AC. I have them all updated to the latest software (10.7.1.0) and the group of them work together with two SSID's that we have configured for our network. Clients are able to connect to the SSID's and receive 85Mbps upload/download speeds which is fine on our 100Mbps connection. However, after about 24 -48 hours, all clients who connect via Wifi and connect from the same office locations experience a drop in speeds to about 15-20 Mbps upload/download speed (and sometime even slower). Upon rebooting the WAPs, the faster 85Mbps are instantly regained for another day or two before speeds drop down once again. We've been unable to determine the cause of this issue and wondered if anyone else has experienced a similar issue.
