Why you need lowest speed?

S-RJ01 is RJ45 SFP 10/100/1000M copper module

Need one more 100 Mbit/s ethernet port. I try plug in this S-RJ01 cooper in to RB2011UAS and change speed on 100 Mbit/s , but it still does not work on 100 mbit. Why i don't understand.... Why mikrotik produce SFP cooper 10/100/1000 Mbit/s if he can't work on 10 and 100 mbit?

Has this even been resolved?
Does this module really only work at 1G?

I have now the same problem with RB2011

Saw the SFP in different shops selling with 100mbit support and now its not working.

I have no idea why its not working.
It should be official supportet
