If both router and range extender have the "wds bridge" feature you can give it a try. It might perform better than universal repeater. You need to give the router and repeater a fixed channel number.

The best scenario is to have 2 identical routers but its still worth a try. I have tried it with two TL-WR941ND V6 routers and it works perfectly fine.
