I have a cluster of 4 WAP561, one week old. I upgraded firmware to 1.1.0.4 when I deployed them. They work perfectly for about a day or so, then become unresponsive.
They usually still respond to ping but not always. When they do, trying to access the management portal it redirects to ([ip]/admin.cgi?action=main), but the page isn't served (no data received). The SSID is still broadcast but clients are unable to connect.
Rebooting solves the problem temporarily, and when they're working they work perfectly. The issue doesn't occur on every wap at the same time - sometimes one or two will keep working for longer.
During the roll-out only 3 users have had access for testing so I can rule out any over subscription issues.
