Adding WAP to ethernet home network

I would like to set up a WAP at home so that we can choose when different members of the family have wifi access.
I am currently using ethernet and a Thomson Speedtouch 546(i) V6 router. We have 3 laptop PCs and an imac, also a PS3 and Wii. Can you recommend a suitable, easy to install, WAP?

you can convert any router into an WAP by following these steps

if you only have Fast Ethernet:

if you have Giga Ethernet:

I like to use routers. They are about the same price and if the main router dies you still have a backup. Also most WAP only come with one 10/100 LAN port. By using a router you have additional LAN ports available.
