I bought this router and use for 7 days. It was fine all 7 days, suddenly there is no Internet connection this morning. I check, reset the router, redo the quick startup. The wan indicated it was connected, when i try to ping google.com it took forever. I tried to redo quick setup again, it failed 2nd time to connect to internet. Then, i brought up my old tm given router dir-615, plug in, and it works perfectly.

Guess i got a lemon unit and need a replacement. Anyone facing this problem?
