Not a Winbox issue.
I can connect a laptop with its NIC forced to 100FDX and see ping loss. I also
see devices downstream of a 100M interface on this router that I monitor for
packet loss and starting when this router was changed, the packet loss graphs
went from essentially zero to around 0.5%.

FYI I use Winbox 2.2.18 100% of the time since 11/3/2011 - maybe try that?

I get the same results with Winbox 3.0 or Winbox 2.2.13. Note this problem
shows up as on other stuff not just Winbox, it's just easy to test with Winbox
because it shows up easily as disconnects or failure to load plugins.
Note that I can use Winbox fine through an interface running at gigabit, or I
can Winbox through this router to another Mikrotik via a 100M interface, the
stress on the interface seems to be when the packets are originating from this
router itself and trying to go out a 100M interface. But I also see low level
packet loss on normal traffic through the interface, although it doesn't show
up as drops or errors in the stats.

I tried multi-queue Ethernet default and it didn't work, even with queue
size increased to 500 packets.
5.26 still works fine. Best way to see problem is to clear Winbox cache so
it has to download plugins.

Don't forget to reboot the unit after making the queue changes.
Also I would suggest to reach out to Brian Vargas @ Balticnetworks and see
if they have any suggestions and or if they can replicate what you are
seeing.

I thought about the first part but didn't try it, I'll try it on the lab
router tomorrow.
No, I don't see anything reported in the stats, as far as they are
concerned, everything is good.

Try something....
change the interface queue to multi-queue-Ethernet-default
and increase the queue size packet buffer for it. (it should be mq pfifo)
Do you see errors / packet loss being reported in the stats ?

I downgraded to 6.25 and still saw the problems.
I don't really want to go back any farther, likely the issue started
with
the new kernel and drivers when 6.x first came out. I figure if I can't
run
any of the recent versions, I might as well go back to 5.26. Unless
someone
knows of a specific cause and how to fix it.

I think some weard problems started around 6.33. There are posts of
different topics about things like Winbox and VPN traffic not working
but
traffic through the device was fine. Some thought MTU changes but I'm
not
sure I saw concrete fixes. I know earlier versions don't do this.
I recently upgraded one of those RouterMaxx 1106 routers from 5.2 to
6.33.1
(I actually configured a new router and swapped hardware). Ever
since,
I
have had performance problems with a couple ports that are connected
to
radios with 100M Ethernet ports. The most obvious symptom is that
Winbox
won't stay connected or can't download plugins, but I also see pings
dropped
even to the directly connected equipment.
I was a bad boy making multiple changes at once, so I've been
gradually
walking them back in the lab on the original router, I upgraded it to
6.33.1
and the problem appeared. I dropped back to 6.31 and it was still
there,
but when I dropped back to 5.26 everything was fine again. I haven't
tried
earlier 6.x versions yet, 6.31 is the oldest x86 version I have handy.
This
is not a radio problem, I can reproduce it with a directly connected
laptop
if I force the laptop NIC to 100M FDX.
Is anyone familiar with this problem? I can't find anything on the
Mikrotik
forums. I guess I can live with 5.26 if I have to, but I'd like to
know
what is causing this. Do I just need to change some configuration
parameter? I know 6.x brought out hardware only queues, but I think
that's
for Routerboards, not x86. Is there a problem with the Intel NIC
drivers
included with 6.x? Any chance that an earlier or later version of 6.x
will
>>> work for me? I see nothing in the change logs about it.
