was it available by MAC address, Telnet, SSH or any other method, or you just tried winbox? It would be great if you tried and let us know more details. Could it be pinged?
I've tried to get to the router by MAC (using winbox). Without success.
Have tried to scan network for present any mikrotik devices (using the same winbox. it's button with three dots). Without success.
Have tried to ping. Without success.
Have tried to listen any network activity using Wireshark. No packets except mine (I was connected to the router by wire).
What else. O, yes. 1 out of 3 boots router could successfully boot so that's how I could downgrade it back.
BTW. I've had the same problem as that fellow from the video - http://www.youtube.com/watch?v=_2fHNR8s1BM
I went to reseller hoping that they will change it for me. But all they did is they changed power adapter. Maybe they were right. I could not argue with them because the router was working just fine. Can that history lead to my problems?
