2 AP stopped working with GS1900-24EP

SwitchAnon

Two of my access points (Unifi) have no internet when plugged in to the switch GS1900-24EP. It used to work just fine. I have three more AP's that works fine with the switch.

How can I fix this problem?

Information:

Switch: GS1900-24EP

Firmware: 2.7.3

My AP's have worked perfect for years with the switch.

The AP's works great if plugged into the router (no switch).

I have reset the AP's.

POE power and cables is not a problem.

It does not matter if I change the port and cables.

When plugged into to the switch I will get internet for about a minute and then it "shuts down" (no or super slow internet).

The AP have the right MAC address and I can't see any duplicates in the switch web UI (MAC table).

The port status is, State: Enable, Up, Auto-1000M.

Any ideas?

Hi @SwitchAnon,

Could you upgrade the switch firmware first since it is not the latest one? Firmware link

If this issue happens again after firmware upgrade, since you changing ports/cables are still the same, please help download the tech support log and share it with me in a private message.
