Sara, try it. http://www.tp-link.com/en/article/?faqid=417

Thanks, I tryed that guide, but it does not work, and the menu is also a little different than the one I have when I login to my router.

http://www.tp-link.com/en/article/?faqid=417 - in this guide everything is explained. What kind of problem do you have? Please exactly describe it.

I did everything in the guide, but maybe I want something more than just making it an accesspoint...
I would like the accesspoint to just have the same name and password as the original wireless.

Now I have a wireless an extra net, but I dont want an extra network, I want to extend the first one...
How to do that?

And the password is the one in the bottom of the new router, and not the one I wrote when I logged on to the router.

Same SSID and password (WPA2/AES) like on main router.

Thanks I think it is working now :D :D

I'm very glad :)
Best regards from Poland!
