How to extend wireless network with ethernet port

[jrsday]

Hi Guys -

I have just done an extension to the house and put in an ethernet cable through to the new bit for hard wired connections thinking this would help - as predicted the wireless does not reach that part of the house but I want to extend the wireless network.

Is there a range extender or something else anyone can recomend that I can plug into the ethernet cable to extend my wireless network to the new part of the house?

Thanks in advance!

Current internet is with BT Infinity and using the BT HomeHub.

Thanks -

Not very savey on all the complex side of wireless networks I'm afraid but essentially I just want to have an extension of my existing network (Wireless N) so I can walk seemlessley between them if needed and the signal to appear as if it is a single source in the house (not several which I have had with the wall socket extenders before).

Money not too much of a concern so long as it works and is fairly easy to set up.

Any recomednations welcom!

Ok - and if I give up on seamless then does it get a lot simpler?
