WAP121 after 1 day AP unresponsive

After 1,5 day the WAP121 unresponsive.

After a reboot I get back to the admin site and the clients can connect again and everything is ok again.

My Network:

1 SG300-10MP FW:

2 WAP121 FW:

The WAP121 is connected to the SG300 and get power over him.

I have the same problem if it uses power from the AC adapter.

In the support log I found the following entries:


Software Version:
