Hex doubles upload traffic by itself

Mon Dec 12, 2022 10:32 pm

Hello there,
I switched to a Hex Router to play around with it and run into a strange problem, wich I can't sort out.

I turn on the streaming software which should use the upload of around 7500kb/s.

The live monitor shows a Stream Bitrate at around 6300kb/s.

Which is a bit strange, but ok.

The Hex Router shows a corresponding upload usage of around 6300kb/s, which is the same as the streaming software shows, so its ok.

This is the first "problem" I ran into. Why is it that the Router does not give me the full speed of my upload?

And now the strange behaviour starts.
After about 10sec of streaming, the upload bitrate in the streaming software gets limited to around 5300kb/s.

This is because the Hex router decides to double the upload it gets, so it uploads with a upstream of 10800kb/s, which is double the rate I am sending to the router.
By that behaviour, my uplink gets fully packed.
Down by provider: 50mbit
Up by provider: 10mbit

Why is it doing this?

When I change back to any other Router I have, everything is normal and I can stream with my set bitrate of 7500kb/s and the upstream gets not doubled.

Does anybody have an Idea, what the hell is wrong here?


Its a totally basic config on a Hex router:
# dec/12/2022 21:08:21 by RouterOS 7.6
# software id = GLYB-6INK
#
# model = RB750Gr3
# serial number = CC210FAF9D8E
