You guys are a little too defensive sometimes
I see nothing wrong with suggesting there is two or more devices with same apparent problem.
Example: I just loaded new ROS on RB600 and all my settings are gone. Hey, I have same exact problem, I loaded new ROS on RB493 and lost all my settings. Yeah, me too, same here with RB532A...
Now there should be nothing wrong with this because to us (and it usually holds true) it is the same problem caused by same ROS.
Now back to reality. People are telling you of strange events dealing with Routerboards and GB eth ports. Mind you I've been in this business (others on here are not new to the industry either) since even before there was RJ45 eth ports. I'm telling you there is something that has shown up on the radar I haven't seen in the last 20 years with the way they are behaving. I can't explain what yet because I don't have the luxery of testing completely - if I have an issue I set the port to 100FDX and move on because I don't require GB connectivity any way. Just take note that like many of the other problems that were eventually identified and corrected - there may very well possibly be an issue here. You guys blow stuff off way too fast as not an issue.
