I have two EAP225 access points in my home, and am running the Omada Controller software on my server at home. Once every week or so, both access points will stop functioning, within a few hours of each other. Sometimes one will stop working 15 minutes after the other stops; other times one will keep working for 3-4 hours after the other has stopped.

When they stop functioning, all wireless clients lose their connection to the access point, and the APs show as DISCONNECTED in Omada Controller. Wired clients continue to work. Rebooting the APs fixes the problem, and they begin functioning again.

At the moment, they are powered & connected via a TP-Link TL-SF1009P POE+ switch. They have been in this configuration for over a year, and have been working just fine until a a month ago, when they started having this problem. I have also tried powering the APs with the POE injectors that came with them, but this did not improve the situation.

Both APs use a static IP address, and their addresses are outside of the range used by the DHCP server.

Any ideas on what might be going on here?
