I just bought DIR-655 yesterday and tried to set it up through the CD but without success. My problem at first was I couldn't get internet connect via router (but PC to DSL modem direct connection is always all right). Then I played around to turn on "Advanced DNS service" then I got internet connection via router to my PC. However sometimes the web site names couldn't be translated by DNS correctly and it resulted in "Not Found" and I am pretty sure those web sites are active and running (as I have no problem to access those if I connect DSL modem to my PC directly). Also I noticed wireless connection was very slow and some You Tube videos would stop playing after around 30 seconds and DSL modem had no further activity at all. Could someone please shed some light on my problem? Why couldn't I use 192.168.0.1 (default IP) as primary DNS (as I got no internet at all if I did so)? Is it really necessary to turn on "Advanced DNS service"? How can I get internet access if I turn "Advanced DNS service" off? Thanks very much in advance!
