3.0rc6 winbox disconnects

winbox keeps getting disconnected on me about every 10 minutes or so… has anyone else seen the same thing?

Yep, but only when I used MAC level connections. IP level connections are ok.

No way.
ip or mac winbox or telnet, it’s the same to me, on a rb 133.
Still got disconect.

Same here.
Routerboard minirouter 3.0rc6 connecting via ip.

tested from half a dozen client machines, all getting disconnected at IP level… also seeing random drops and lost packets across the ethernet interface, running on a 532…
