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!
