Windows 7 will not pull ip from router but will connect if set static

I have a Windows 7 home premium 64b bit laptop that will not pull an ip from the router on wired or wireless connection but if I set the nic with a static ip I can connect to the network and get to the internet. Any ideas?

Have you tried altering the DHCP range? I had a similar issue, and raised the starting DHCP address to x.x.x.100 and everything started connecting properly.

It will not connect to any network with different IP ranges.

I also ran TCP ip stack reset

Is DHCP turned on in the router?

How about forcing the NIC to 100mb full duplex, or half-duplex if that doesn't work?

I would assume this is a home network and the router is the home router as well.

Can you check the network configuration on your laptop.  Run the ipconfig /all from the Command Prompt and then post the result.

What router is it?  Can you check if DHCP setting is configured correctly and activate.

Can you check what the default gateway on the laptop?

Also do a TCP/IP repair. Here is a Microsoft article about that:

Hey.

From the start menu search box type "services" [enter]

Is "DHCP Client" started?

DHCP is not started, when I try to start it I get "windows could not start the DHCP client service on Local Computer.

Error 1075: The dependency service does not exist or has been marked fro deletion.

So then all the more reason to try the TCP/IP repair.

Also, open cmd.exe with Run as Administrator and at the prompt, run SFC /SCANNOW (System File Checker). Perhaps run this first and then repair TCP/IP.

Can you post the output of the ipconfig /all?

Also check the Properties of the Network Adapter, make sure that no DNS or WIN entry anywhere.  Obtain IP and Default Gateway set to "Automatically".

I would try connecting up to another router to determine if its the system or the router then troubleshoot further.

you need to start dhcp client service and all be ok
check dependencies of this service
go to the device manager window and in menu "view" check "show hidden devices" then in the network devices section remove all devices and press F5 button for renew, windows will automatically re install all deleted drivers. then reboot and try to give dhcp settings.

Try uninstall/re-install NIC driver.
