Windows 7 Network Error: Local Area Connection Doesn't Have A Vaild IP Address

Ok, so I recently plugged my laptop into my Router with a cable, but when I plugged it in via cable, I get an error saying that my Local Area Connection doesn't have a valid IP Address. It works perfectly when using wireless and works on my Vista desktop, but not on my Windows 7 x64-bit laptop. Does anyone know how to fix this?EDIT: It turns out that it's my router...I connected directly to the modem and works perfectly. And I assigned a new IP address, so everything is good, at least, once a I get a new router. Thanks for your support.

the router isnt issuing the laptop with an IP address. give it a few minutes, if it doesnt work then try repairing the connection.

I left it for a while, but it didn't work. I tried troubleshooting it, but Windows couldn't fix it, nor could Network Magic.

i seem to have a similar issue...when i'm at my mom's, i try to use a neighbors internet (wireless), and have the same error...waiting, and repairing the connection does nothing...i thought i was doing something wrong. =/

Windows just came up saying that there's an IP Address Conflict...whats going on?

two computers having the same IP address. usually because one or both are manually set, or the router/dhcp server running out of addresses in the pool.

How do I fix this?
