Just upgraded to comcast 50mbps. When I connect my laptop wired str8 to the comcast modem I get about 46-48mbps but when I go thru my comcast modem + router dlink 825 and wired pc, I get download speed of 29-31 mbps. Anything I could to increase my download speed when connected modem-router-pc (wired). Any settings in my dr-825? please help
