Hello
I cant get full speed on my TD-W8980. When i connect directly to my modem i get full speed. When connected with router (WAN mode) i only get 60-70 mbps

What can be the problem?

What kind of connection do you have between computer and TP-Link?

I use wired ethernet. Connected directly to modem i get full speed. Connected with the same cable to router and only 60 instead of 120

I thought i have fixed the problem... I have not. I replaced cable between modem and router. Old cable was 10/100. New one iss 10/100/1000. But still. I dont get 120mbps. Still getting max 90

Do you have any modem unit from your ISP?
