I'm running an ASUS RT-N66U router/accesspoint with firmware release 3.0.0.4.376_3861, which is the latest release. Until recently we were using WPA2-Personal authentication which was working fine. We signed up with a Radius-as-a-Service company, which is using FreeRadius 3.0.7. I changed our 2.5Ghz wireless network (there is a 2.5Ghz and a 5Ghz network) to WPA2-Enterprise and to authenticate with the Radius service. We can authenticate just fine, and the network seems to work fine, at first. However, soon after switching to Radius authentication, users starting complaining that they loose connectivity when their computer (usually a Mac running OSX 10.10.5) wakes up from sleep mode. The way they usually notice this is because their HipChat program says it's trying to reconnect. By switching to another network, and then switching back to the 2.5Ghz network, they can reestablish the connection. I was not expecting connectivity problems. I've talked to the service vendor and they aren't seeing anything in their logs. I'm going to update a test Mac to 10.11.1, which came out yesterday, to see if I can replicate the problem. If so, I suppose the next thing I'm going to do is switch to a different router/access point to see if the problem is router specific. I found a web page https://jamfnation.jamfsoftware.com/discussion.html?id=14693 where this problem was discussed but nobody has a solution. Has anyone on this list seen this problem when switch to Radius? Do you have any suggestions for how to troubleshoot this problem?
