Can someone tell me wha my network connection which should be 20/3 work only to 10/3?
I check speed on interface and from 10M switched to 100M and nothing happens.
Any idea? Thanks.
No one? 
Baaad!
Are you using the default configuration? I have an RB751U-2HnD as well on a Comcast business connection and it is able to route traffic to the internet at speeds of 100Mbps/50Mbps which is the connection speed I am paying for. If you plug back in your old router, do you get your 20/3 speed back?
Yes, i’m using default configuration, but customized for myself.
Yes, in my old router work fine 20/3.
What can I do?
