Hello Wirelessrudy,
I’ve read your posts for 2 or 3 weeks ago, but I think that my problem might be different than yours. If I remember correctly, you’ve described that your eth interfaces are flapping. Does it mean the data flow is interrupted and then continues on its own, doesn’t it? But in my case, the data flowing completely stop (the eth interfaces freeze - no rx packet received anymore), and only the reboot solves this problem.
I haven’t made a support request yet, because I’ve believed that, it might be a hardware problem especially with RB493G’s. But since when I’ve changed RB493G to another one, then changed them into RB435G’s (and it couldn’t solve this problem), I’ve searched the forum for similar sympthoms. I’ve found SXMU’s post (http://forum.mikrotik.com/t/radius-server-not-working-in-2-8-11/127/1), that is exactly the same problem than mine. Do you think your problem is that the same?
