@Sigdoc,

Connecting a Router to another Router via a wireless connection requires a specific operation mode(Client Mode) which is not available on those models and is really only seen on Travel rotuers. This setup will not work in AP mode or Router Mode - and isn't really recommended due to stability issues. 

I think you may be better off looking at a Mesh solution that is meant to communicate wirelessly or looking at systems such as CPEs that will provide a better connection.
