Sorry for my english.
I have a problem.
My router is Mikrotik RB-750G. I have tried to upgrade RouterOs on It to 5.12.
I followed instructions in manual on this page:
http://wiki.mikrotik.com/wiki/Manual:Up ... ing_Winbox
I just copied routeros-mipsbe-5.12.npk via WinBox and then rebooted.
After that router always reboots, a I suppose: net link (to which ethernet cable connected) is blinking, then all leds are flashing simultaneously and off. And my computer trying to get IP via DHCP, then It doesn't and sayig that cable unplagged. And again and again.
So I'm trying to update RouterOS with BOOTP. I have generated virtual machine with RouterOs 4.17. Have puted routeros-mipsbe-4.17.npk on It. Tuned DHCP. Then I see in logs, that my device getting ip, getting access to file, then closing connection, and I see that It reboots again. And so on. By the way my device gets IP only if It connected via 1-st interface. Other don't even get IP.
By the way, I have serial cable from Cisco (on one side It have RG-45, and on other COM). Can It help? I just don't understand how to connect by serial console if It possible at all.
So, what is yours advice?
