We have Aerohive 330 access points in all of our dorms. Up until recently, we only had 1 SSID broadcasting on them with all rates below 11Mbps on the 2.4Ghz radio disabled. Right after spring break we enabled a second SSID called 'gaming' for the primary purpose of allowing the Nintendo Wii to connect to our network. In our experience, the Wii will only connect if 1Mbps is enabled on the 2.4Ghz radio. After enabling the gaming SSID, we started receiving calls about wireless problems in the dorms connecting to the orginal SSID. The complaints weren't that they couldn't connect, but that they would intermittently lose their connection. One of my techs actually experienced it one time. From his perspective, he was still connected to the wireless network, but he couldn't access any network services and his network tray icon said there was limited access. I could no longer ping him from the core, but I could ping the access point. I ssh'd into the access point and the access point was showing the client as connected. In our troubleshooting over the last couple of weeks, the issue was so intermittent that we only experienced this a couple of times ourselves, but it was happening to students across all dorms. We eventually had to remove the gaming network from the access points. I know this is a long shot, but does any of this ring a bell with anyone?
