I had limited connectivity when I used one wireless router on my second floor and wanted to connect while at opposite ends of the house on the first floor. My existing dlink router was old and I upgraded to a dlink dir-655. While I gained somewhat better connections downstairs I was still dropping off when I moved to different areas. I then ran a cat5 cable through from upstairs to downstairs to the opposite end of the house and purchased an identical dir-655 router. My network looks like this: internet>>2nd floor router(2'away)>>cat5 to downstairs>>1st floor router. My problem is that I can't access the internet through the first floor router. I show I have good conductivity to my router, but no connectivity to the internet. I attached a cable to LAN 1 and to my laptop but same results. I tried all the other ports, same thing. I then pulled the cat5 cable and connected straight to the laptop. Have internet connection, so I am assuming my cable is good. Placed a switch I have in between the cat5 and the laptop just to see if it would connect and it did. Any next steps you can recommend? I'm out of ideas other than I have a defective router, which is not impossible but I would like to prove that before sending back. thanks, jw
