need help using ethernet switch

[polishdrumsticks]

hi,
i need some help using a 10/100mbps ethernet switch.
basically i have a wired LAN set up at home. all connections are taken on the router downstairs and i want to connect both my pc and nintendo wii to the ethernet wall point in my room.
i bought an ethernet switch as i was told this was the thing to do. i am using straight ethernet cables and connected the switch to the ethernet wall point using the link port on the switch. when i connect the pc to the switch the light comes on on the switch but i cannot access the internet. the wii doesn't work either.
what am i doing wrong?
any help is very much appreciated!

Does the port on the wall work without the switch?

hiya is the switch connected to the router? (sorry if this is a silly question)

if it is does the router show that a connection between the router and the switch is active?
