Airport extreme and linksys ethernet switch don't work

[nibuoy]

Hi!
I have my linksys ethernet switch (this one: http://www.amazon.com/Cisco-100-5-Port-Workgroup-Switch/dp/B002N17ZSE/ref=sr_1_1?s=electronics&ie=UTF8&qid=1308598814&sr=1-1 ) and an apple airport extreme.

However, If I connect my computer to the ethernet switch, it says I have no IP address and cannot get a signal. In addition, my xbox can't connect to live.

When I connect my computer directly to the extreme, it works perfectly fine.

Any suggestions?
Thanks

So I've been through this. From your Internet device (cable modem etc) connect the airport extreme. Then from one of the Internet ports on the AE hook up the switch.

Which port are you connected to on the switch. I think there is a specific port that you need to plug into for it to work. It's either #1 or #5.

I was able to do a search for the switch on Linksys' site and found the instruction manual. Are you connecting the router to the proper port? According to the manual, the port to which the router should connect is the sixth port from the left. Then you attach your computer to ports 1 through 4 (according to the same manual, port 5 becomes inactive once a router is connected to the uplink port).

The setup is correct (I just double checked), yet I still get the no IP adress error.
Also, according to the linksys manual, all the lights are correct.
I'm pretty sure it's not a problem with the ethernet switch, because it used to work perfectly fine before I switched to the airport extreme, when I used an old linksys router.
