Orange Pi Lite didn't boot with wifi antenna

After strugling with the powersupply at the beginning I got a better one and at least I managed the first time to boot into Jessie desktop. But, dont't ask why, I booted without the wifi antenna plugged in. Everything was ok until I shuted my orange pi lite down and plugged the antenna back in. I restarted it. The problem was that after seeing some boot lines the screen turned black and the green led vanished for a second or so. After that notthing happened except when I pluged the power out and than back in. But allways the black screen returned after some boot time.So I tried to rewrite the image to the SD-card but I didn't manage to boot up when the antenna was connected. The boot process only get to:
addrconf(netdev_up) wlan0 link is not ready
The later time i rewrited the image and rebooted the orange pi it failed to initialize due the same wlan error
Followed by something like that:
------[cut here]----
kernel/watchdog.c:255%20watchdog_timer_fn+0xf8/ox2a8()
----[end trace .........]---
systend-journald[180]: Recieved SIGTERM from PID1...
systend[1]: Starting Journal Service...
Starting Journal Service...
and than it stopped

I hope someone knows how to fix this because I'm running out of ideas.

Most likely your file system on sd card got corrupted due to power cuts. If you haven't done anything, rather start from clean image otherwise clean and fix filesystem on some linux pc.

The black screen come probably due corrupted file system but after that I wrote a new image with rufus on the sd card but I got only to the point where it says that the wlan0 link is not ready.

@nona

OPI LITE wifi works flawlessly if you follow the Armbian instructions. Stable sufficient power supply is crucial.

I tryed mesuring the voltage during the first boot and found the error probably. The dc power supply which is rated at 5V 2A went down to 4,39V during boot up and so I get probably this errors. Hope the next power supply I get is not only rated at 2A but really support it without such a voltage drop.

Thank you for the answers!

Maybe this isn't your problem, but it was mine, so check that you're not having this problem. I bought an orange pi one and a 5v 2a power supply, it worked fine but when i plugged in the wifi system would freeze after few mins.! After lots of struggles i found out that the power supply gives 5v 0.6a!! And it was a chinese brand. I bought an other power supply (chinese again) it said 5v 2a but gave me 5v 4.5a. Everything worked fine without a problem. So check that you're not having this problem. (I used a digital ohm-meter to know the A of output)
