Hello guys
I´m trying to setup 2 Cisco Aironet 2802e-e-K9 AP's. One is also the controller running the ME mode (master) and the other one is running the CAPWAP mode (slave). So far so good, but after booting the AP's, the wifi is up for about 3-5 minutes and suddenly it "crashes" or something. It seems to be active but i can't see the ssid on the clients anymore.
I'm searching for a solution very long time now but i can't find out anything. Maybe someone of you can help me finding a solution?
LED's blinking red, green, blue in a row
AP's in agroup and one wifi network.
Are there any MESH settings to do?

- Could be a powering problem, reboot the AP and just after boot connect to it and issue the command show logging , or have a console attached and scrutinize the boot process,

Hello! Thanks for the answer!
This is the log since last reset, on first sight it seems like a power issue like you said, am I right?

I'm using the Cisco AIR-PWRINJ6= they're recommended by Cisco for this AP model. They deliver about 30watts, should be enoigh, that's why I'm wondering why PoE should be a problem. Are there any PoE settings to do in the config?

Yes should be enough. Like @marce1000 could be a faulty unit - try another to be sure.
You could try upgrading to https://software.cisco.com/download/home/286304498/type/286289839/release/8.10.181.0 just in case it's a known bug although I'm sure we'd have heard about before now.
