IP won't assign

I can connect to my router fine with my wired pc, and my laptop wirelessly, however I can't connect to the router with the laptop wired. It says "the network did not assign a network address to this computer" Any fix? I would be fine, except I can't play Bf2 over wireless that I know of.

 

never mind, I can play it over wireless. But still, if possible I'd like wired because it's less laggy.

 

well make sure that the "local area connection" is enabled on the laptop. Also check in device manager (ight click on my computer select properties>hardware (tab)>device manager) to see if the network controller is working properly(no re x's or caution signs). With all that good and well, if it is not giving you an ip then make sure one is not already assigned manually (network connections>local area connection>properties>internet protocol> and select obtain ip address automatically). With dhcp turned on and the device working correctly ytou should be fine. BUT if this still doesnt work then follow this: start>run and type in cmd and hit enter. From there type exactly this:

ipconfig /release "local area connection"
hit enter
ipconfig /renew "local area connection"
hit enter

Make sure that the name in the parenthesis is the exact name of the wired connection in network connections, and yes the parenthesis are required.

so to sum up we have verified that the network controller is enabled and the driver is working well and fine. We have turned off(if it was on) and/or enabled dhcp, and renewed the ip from the router dhcp server. Let me know how it goes.
