I've been running a 2590 for roughly 1 year. I started off with firmware 1.20 and learned soon after implementation that the wireless would drop. After looking into this, I found that it was OS independent and it seemed that it could be a stuck beacon and a reboot of the access point. I tried updating the firmware to see if that would help, now I am running:
Model Name DAP-2590
Firmware Version 1.25 15:41:33 08/31/2012
System Name D-Link DAP-2590
Once I've updated to 1.25, I have noticed more problems.
1. The access point seems to go down (possible due again to stuck beacon), and not come back up. The access point is running via POE and when the wireless is unavailable, neither is the web interface. When this happens the only way is to fix the issue is a hard reboot of the access point. Once rebooted, the access point seems functional in all respects.
2. Today I noticed second problem that required a hard reboot.
I have the access point setup running two wireless networks with VLANS.
Private network lets call the SSID Business-Staff. This is password protected via WPA2.
Public network with SSID Business. This is open with no password.
Today I was notified that wireless was not correct, and with two devices I saw the following:
Businecs-Staff (Open)
Busineks-Staff (Open)
Business (Protected)
Note the misspellings and the wrong configuration. I was able to get to the web interface, but when telling the access point to reboot, it seemed to hang, and then required a hard reboot. Upon looking at the logs, I see normal traffic of association and disassociation and then silence from the access point until I started looking into the issue.
Is there a way to prevent the hangs and and the reboots?
