PC on bridged modem is 120 mbps download; via CRS router it drops to 30-50 mbps

Hi All,

I am using a bridged cable modem from my ISP which is capable of doing 120 mbps down and 12 mbps up.
Used speedtest.net to test it with my laptop which has a 1 Gbps network port.
I got the dowload speed as expected; even 122 mbps according to my test. Awesome result.

When I connect the laptop to my new Mikrotik CRS125-24G-1S-2HnD-IN I can only get 30-50 mbps download. Upload speed remains 12 mbps though.

The Cable Modem is connected to ether1, some of the other ports are in use by computers. Router CPU % on average is usually no more than 15%.

What does the command /queue interface set [find] queue=ethernet-default exactly do?

I have no idea how to solve it. Please help.

P.S> In the near future I want to use my new MikroTik on a new 500/500 mpbs fiber optic connection; still to be ordered.
First waiting for the router to function properly.

Kind regards,

Ton

Not sure why, but the following command may have done the trick, it seems:

/queue interface set [find] queue=ethernet-default

My connection has jumped to 12up/112down mbps on a cable link. It’s evening now, so I hope the connection will be even better when nobody’s online in the neighbourhood.

Note: it took a few minutes before the applied change actually worked. So be patience.

Try to set ethernet default queues for the ports.
Anyway, don’t expect performance miracles in natting and routing and firewalling from a switch. Check the difference between a switch and a router.

Another major discovery today. Internet Explorer 11.0.9600.17498 and Firefox 38.0.1 both constantly tested via speedtest.net at 12up/128down Mbps, while Google Chrome version 43.0.2357.65 m consistently performs poor at 12up/60-90down Mbps. Do others have the same experience? Please let us know to find a possible pattern here.
