Plz , any body help me fix my RB ,i still waiting any experience one has see this problem before
Have you tried connecting to the routerboard using the “MAC” method? In that case it’s IP and such don’t matter.
Please see: http://wiki.mikrotik.com/wiki/Initial_MAC_Winbox_Connection
I think I might have the same problem, also with an RB750GL.,
After booting the unit is responsive for a couple of seconds (30-60) and let me connect, but afterwards gets disconnected and is unreachable until next reboot.
I have installed RouterOS 6.12 via netinstall several times, the last time only put the system package on but nothing changes.
After install and reboot I have managed to setup an IP address on an ether port but after 1 minute, I can not connect anymore to the device.
Also found that after some time, when a connected ether interface gets disconnected, the LED stays on and also blinks once in a while.
Another thing I noticed is that when the unit is unresponsive it looks like it is acting as a plain L2 device.
With no config in the malfunctioning routerboard I happen to get an IP address from any DHCP server connected to the broken routerboard, while my PC is connected to a different port of the broken routerboard. But since no config is applied, all ports should be on their own, not passing any broadcast traffic or what so ever.
I have managed to pull a supout.rif file from the device short after boot and sended it to the MikroTik support.
I hope they can find any issues with the unit.
