Just out of interest, do either of the following links work (they are both non-routable ip addresses so they will either get something connected to your home network or they will fail so they should be perfectly safe)?
http://192.168.2.1
http://192.168.2.254
If one of these links work on your network - and it takes you to the web configuration page of an ASUS router, then that is probably the ASUS router that is still in router mode (and needs to be configured for Access Point mode).
If, on the other hand, one of these links takes you to the EE router web configuration page, then, and only then, try the same with:
http://192.168.1.1
http://192.168.1.254
Again, if this takes you to a ASUS router web configuration page, this will probably be the router that needs to be reconfigured to work in Access Point mode.
