I'm using 16mbps ADSL2+ line. When I use Zyxel ADSL modem itself connect to internet, I can get actual download speed at 16mbps. However if I connect Cisco 1700 bridge with Zyxel ADSL2+ modem. The internet works but I can get actual speed only at about almost 10mbps. Why is that? Is it a limitation of 1700 series router? or it is my configuration?
This is my dialer interface configuration
