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.
1 SG300-10MP FW: 126.96.36.199
2 WAP121 FW: 188.8.131.52
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: 184.108.40.206

I hope someone can help me.
I am having the same issue. The device is own, but IP connectivity is not working. I tried disabling spanning-tree by configuring the device as an edge port. Any update if this issue is resolved?
I have two of these devices, both have static IP addresses. I cannot ping either device until after a reboot. I have tried disabling spanning-tree and setting the device as edge port. The switch ARP table does not show the MAC address of the device. The switch ports show up and connected. I have now hard coded the speed and duplex to 100 full on both devices. The Manamgent IP is in a VLAN, and I have not tried moving it to VLAN 1. But making the change would cause some security issues.
The SSIDs are being broadcast, but when attempting to connect the message unable to join network is displayed. We have tested with MAC, Win7, Android and iOS devices and have the same issue with all devices. I have not yet tried changing any of the advanced wireless features.
I too have the same problem on my 3 wap121
they become unresponsive after approximatively 24 hours uptime.
firmware version 220.127.116.11, power from POE, 3 different SSIDs enabled, WPA-AES security
for now i've configured my switch to disable the ports for 5 minutes at night to reboot the APs
Please do some changes in your AP and monitor unit 24 hours. Access unit GUI and do this following
go to Wireless --> Radio
in redio change
Channel to 1, 6, or 11
change Beacon Interval to 400
change DTIM Period to 4
Lefact Rate Sets: uncheck 1 up and down, uncheck 2 up and down
monitor unit 24 hours
I tried the settings you suggested on one of my WAPs, and it has now an uptime of more than 2 days, never had more than 36 hours before.
I keep monitoring it and i'll let you know in two more days
Thanks for your help
unfortunately, i haven't been able to get this problem resolved. With these settings, my APs are working a little longer but they finally are unresponsive.
I configured my poe switch to disable the port at night so that the APs reboots every night.
I'm sad to say that in the end the solution was to throw all of our WAP121s in the trash where they rightfully belong, and we bought from Aruba instead. Since then we haven't had a single issue.

I am sorry to hear that you are experiencing this issue. If you devices are in Cluster Mode or Single Point Setup, I would ask that you disable that as a test. Also, please go to the Wireless-Bandwidth Utilization tab and disable Bandwidth Utilization and as a last modification please go to the Wireless-Radio tab and under Legacy Rate Sets supported and basic disable rates 1, 2, and 5.5.
If this does not improve your issue, please call our support center and open a case so that one of our engineers can work directly with you.

In researching this issue I came across another forum and the solution was to rollback firmware to factory version 18.104.22.168.
I have not tried it yet, but am curious if you ever attempted this fix?
