I have a TL-WR941ND Wireless Router. The WAN port is NOT plugged with any cable. However, the router is internally configured to the ISP username and password as if the WAN port is plugged with a DSL cable. One of the LAN ports is attached by cable to a TL-SF1008D switch.

Router is providing internet perfectly. Is that normal? Please can someone explain this to me!

Is your internet connection plugged into that switch? If so, the ISP device may be acting as your router. –  Jim G. Jun 14 '13 at 15:50

You're using your router as a bridge and access point. It is not doing any routing -- some other device connected to the switch probably is.

If the router is not connected to the WAN, then the WAN port shouldn't be connected to anything.
