Hi there,
you've tried to connect via ethernet port, right ?
Hmm...
Have you even read my post?
Maybe I wasn't very clear about my problem. Let me try again.
"When I apply power (USB or PoE), the power, AP and Ethernet LEDs are lit instantly. And that's it. Ethernet cable not required to have an on state Ethernet LED. The WLAN LED is turned off, no matter what. And there is no Wi-Fi signal as well."
After the mAP lite received power supply, the Power, the AP and the Ethernet LEDs are ON, until I turn of the the power supply. No further activity. No Wi-Fi signal as well, so I cannot connect to the unit via Wi-Fi, and there is no MikroTik-* SSID as well. The mAP lite won't boot.
Here's a picture of the situation:
Again, note, that there is no Ethernet cable connected to the unit, and the Ethernet LED is lit as well. And this state remains over 12 hours (tested).
I've got an another one of this mAP lite. When I apply power to the unit, the same conditions are met as with the faulty unit, for about 1 seconds. Then all the AP and and Eth LED turns off, only the Power LED remains lit and after approx. 10-15 seconds, the Wi-Fi LED turns ON, and the unit can be accessed via Wi-Fi.
So, based only my assumption, when initially three of the four LEDs are lit, that's the self-test phase of the mAP lite, which fails. That's why the faulty unit stops there, meanwhile the working one continue to successful boot eventually.
