I bet it exists and you just don't realize it.
Try this (assuming ETH2 is one of the RB ports)....
type: mii-tool -R eth2
(which will hard reset card)
When not working it will read.
eth2: 100 Mbit, full duplex, link ok
To Fix type... mii-tool -r eth2
(which will force auto-neg.)
When working it will read.
eth2: negotiated 100baseTx-FD, link ok
To test/prove which case above is or isn't working...
It should be understood that the reported port/speed detection of the remote
device may or may not be reliable or trusted. To test if it negotiated
properly you can simply do a speed test and compare the difference in each
of the two above examples. I use PingPerf but you can use Iperf also.
For testing... Hard set your remote radio device to 100mbFDX. Then on the RB
PC do the Mii-tool with -R and -r.
When mii-tool reports "eth2: 100 Mbit, full duplex, link ok" you will get no
better than half the throughput/speed that you get when it reported "eth2:
negotiated 100baseTx-FD, link ok"
I have confirmed this condition with the remote device being a
STAROS/WARboard, Trango AtlasPtP, and Trango 5830.
I replicated it on all our routers that had RB44s, about 15 or so. I could
hard set the remote device at ANEG or a set configuration (10 or 100, half
or full), and the RB would demonstrate the same characteristics. I didn't
catch it at first, until I noticed some radios where running slow accross
the ethernet, when RF tests were testing fast.
I'd be interested in seeing if you can replicate it.
Otherwise, I got a driver or config file problem.

Hello Tom,
Interesting...we've never seen this problem before with countless RB44s
deployed. I suspect it isn't solely a RB44 issue, but probably a hardware
combination of some sort.
Best,
Brad

RB44.
We've used combo of 3 RB44 (via-rhine) in RouterPC for years at many cell
sites, with great success. Never had habitual problem with Lockup. Never
tried more than 3 cards. We use Mandrake Linux though, not Mikrotik.
However, the problem we have with RB44 is they do not auto-detect correctly
after the cards are reset. (For example rebooting PC or doing a
Mii-tool -R).
We see it is not correct by seeing incomplete speed descriptions viewing w/
Mii-tool. To fix, do Mii-tool -r to force auto-renegotiate. This is a BIG
pain in the neck to remember to watch for, as otherwise cards are left with
a Duplex Mismatch to radio.
We are investigating whether this is possibly a driver problem, or config
file misconfig, apposed to the card itself. Not sure.
For that reason we prefer the MT RB24 card w/natsemi.
We are planning on testing possibly using the new RB44G, since it uses a
different driver (Realtek)..

Did a little research on Mikrotik and number of MT RB44 nic cards used.
Here
is the link.

I need more horsepower at one router site.
It's got a MT RB532 (233MHz/32MB) and it is pegging at 100% at times,
mostly
in the 85% range, though. The location has a 19" rack (only about 18"
deep,
though). Need 8 FastEthernet ports. No wireless. Want to user Mikrotik
RouterOS.
Can anyone recommend a box for this?
Thanks.
