The 1720 worked fine with my old Dlink router. I got an Asus router and the 1720 won't work. I connected the 1720 to the router. I logged into the web page setup and did the passwords, etc. I then disconnected the 1720 from the router and plugged it into the wall. I pressed the WPS on the router for 10 secs, then I pressed the WPS on the 1720 for 4 secs. The light on the 1720 blinked green for awhile then solid red. I read the manual and can't seem to find what I'm doing wrong. Please be gentle - I am not too tech saavy. ha ha ha.
