Connect Router with Access Point by WiFi

Is it possible to connect a Router with an Access Point by pure WiFi?

There is a technology called Wireless Distribution System http://en.wikipedia.org/wiki/Wireless_Distribution_System.

I don't think your specific router model has any custom firmware that can be flashed for WDS support.

Normally users would flash a different router firmware on to their router such as DD-WRT or Tomato, which would "unlock" WDS support.

I think what your suggesting is possible without trying alternative firmware (DD-WRT, etc.) Although I could be wrong.

According to the manual for the TD-W8960NB WDS is possible with that model. Page 78 on the user manual has some more details.

For the TL-WA501G I suggest having a look at the following link.
