Hello everyone, first-time poster

Every now and then while im browsing the internet, it would stop working. I checked my event log and it says I have a Dhcp error. I clicked on it and it shows “The IP address lease xxx.xxx.x.x for the Network Card with network address xxxxxxxxxxxx has been denied by the DHCP server 0.0.0.0 (The DHCP Server sent a DHCPNACK message).” I am guessing that this is a pretty common error because I see a lot of others having this problem when I searched Google. I have tried ipconfig/release and renew and netsh int ip reset catalog, but to no avail.

Right now the internet is working fine since im able to post here, but sooner or later its going to stop working =p. I don't know what to do. I am not really tech-savvy when it comes to computers. Im using Windows XP and Netgear WGR614 router.

Also describe the rest of the network and connected computers. Is this the only computer having issues, or are other attached computers also having problems? Wired or wireless?

Yes, my other computers are being affected as well. I've tried both wired and wireless and the problem still seems to persist. Thanks guys for helping out.

Important information, this means it's a common component, either the router, the modem, or your ISP.

Name of your ISP (Internet Service Provider).
Make and exact model of the broadband modem.

Please do this as well.

Hold the Windows key and press R, then type CMD to open a command prompt:

Type the following command:

TRACERT google.com

Right click in the command window and choose Select All, then hit Enter.
Paste the results in a message here.

If you are on a machine with no network connection, use a floppy, USB disk, or a CD-RW disk to transfer a text file with the information to allow pasting it here.

Do you have the same issue connected directly to the modem?

[B3YOND]

it works perfectly fine when i connect directly to the my modem.

[JohnWill]

Try doing the following.

Upgrade the firmware on the router to the latest version from the manufacturer's site.
Reset the router to factory defaults and reconfigure.

If it still has issues, I'd be shopping for a router.
