RESET Router

replace 433UAH in office with 750
go home mess with the 433 for a bit before… /system /reset

and now… nothing.

no ips (192.168.88.1) no MAC telnet, not on my mac with parallels using mac address in winbox or on xp with neighbor viewer.

eth1 2 and 3 will blink in succession occasionally and xp reports the network connection as being connected then unplugged when this happens.

Have you pc connect with ether1?
Try other ethernet interface

yeah tried eth1-3.

I’ts dutch but the pictures speakes for itselfs

Gonna try Netinstall later tonight but my question remains from OP

“Why are the eth lights cycling periodically on the RBoard and disconnecting/reconnecting my laptop when they do this?”

must mean something

I have the exact same issue and my RB speaker sounds like a dying cricket each time it cycles through it’s boot. Did you ever find a solution to this?

not quite a solution, gave it to a local MTCNE who had all of the right stuff (as in using windows with proper comm cable) and he was able to revive it
