DIR-868L advancedtomato - crashes to recovery.

Hi all,

I have an issue with my dlink DIR-868L rev. B.

I've flashed the latest advancedtomato, all Goes Well exept 5Ghz that i to activate via CLI.

Then after a few days it seemed slow so i tought reboot...

Goes into dlink recovery mode (amber led blinking).

So i'm reflashing stock now but what to do if this happens again ?

Thanks in advance!
