DHCP client cannot get an valid IP address

[AngranYang]

I have a problem with DHCP ip assigning.  I configured dhcp server on the router 2921 with 192.168.1.1/24 but the laptop is get invalid ip address of 169.254.x.x. The brand new laptop is running Windows 7 64bit. Here is a list what I tried:

- ipconfig /all got us a 169.254.x.x ip address and no default gateway

- ipconfig /release gave us the same number

- ipconfig /renew failed

- configure static IP address of 192.168.1.2 and it works

- pulled power cord out of router for 10 secs and pluged in agin.

- shut computer down, pulled network cable and restarted.

- ensured firewall was off

- went to start-run-services.msc and made sure DHCP service is started and automatic

- changed another computer and the problem was same.

- typed "show arp" command on the router, it couldn't see the laptop unless static ip (192.168.1.2) is set.

- typed "debug dhcp" command, configure the laptop to be dhcp, pulled out the network cable and pluged in, but no debug information was shown.

I looked up through the internet, and saw many people asking similar questions but didn't get a clear answer. This issue is discribed as APIPA - Automatic Private IP Addressing, which means the client cannot find any dhcp server any assigns itself a private IP. Combined with the debug information I drew conclution that the computer was not sending any dhcp request to the server, but I don't know why, nor how to fix it.

The config on the router and the topology is not complicated like I attached below. Anybody please help me cause I am really bothered by this issude. Many thanks in advance.

Hi.

The service dhcp must be enabled with the global configuration command:

service dhcp

Hope this helps.

Best regards.

Massimiliano.

Would you assign a static IP to the PC, verify that it works, and then post the output of show arp?

Thanks for the suggestion, I would try once the customer is back to work after weekend.

[AngranYang]

Yes, I have proved it will work after assigning a static IP to the PC. There will be 192.168.1.2 and a mac address on the output of show arp. If no static IP is set, this mac address won't be there.

It's a non cisco 8 port switch without any configuration. I don't know the model because I am remote controlling the router helping the customer with trouble shooting. I guess there should be no problem with the setting of switch.

[Jeff Van Houten]

What is the complete config and model of the switch?

  If you are plugging the devices into a cisco switch make sure all access ports have the "switchport host"  command applied to them and then retry . Also fix this " no service dhcp " . 

[AngranYang]

The switch is non cisco 8 ports with default setting, I guess the problem is probably this " no service dhcp ". I will try and let you know. Thanks.

Hi

Did you check the cable ?
