My Sky router is pretty bad at providing a good wireless coverage.

I already had a Old style wireless Apple express, pretty sure it is only B and G.

I have brought a Apple Express new style today.

I have the new Apple Express connected to my router and my routers wireless switched off.

I have asked my old Express to join a network which it does and the status light is green. it is plugged into the wall and has no ethernet in it.

However, when i get my iphone and start searching for wifi next to the extender it does not see a wireless network.

Now i have read many things and am confused. Is it pushing internet out of its ethernet port and not receiving and boosting wifi?

Any help appreciated as always

Many thanks
