My internet connection drops constantly. I cannot determine whether it is a hardware, driver, program, or settings issue. Connectivity is worse when wireless laptop is online (streaming a movie or playing interactive games), with dropped connections every few minutes.

I stream a radio station 24/7 through RealPlayer on the wired desktop computer, my girlfriend watches movies and plays interactive games on the wireless laptop where the content/games is through Chinese websites)

*Comcast Cable Internet Connection, Linksys BEFCMU10 Cable Modem, Linksys WRT54GX2 WIreless-G router.

*Desktop: HP Pavilion a1610n (hardwired) using NVIDIA nForce Networking Controller, Windows XP ME, SP2

*Laptop: Dell E1405 Inspiron using wireless card (Dell Wireless 1390 WLAN Minicard), Windows XP SP2


The following events (1002, 1003) seem to occur most often and always back-to-back when I look at the System Event Viewer. For example:

Warning; Source: Dhcp Event: 1003

Your computer was not able to renew its address from the network (from the DHCP Server) for the Network Card with network address ************. The following error occurred:
The operation was canceled by the user. . Your computer will continue to try and obtain an address on its own from the network address (DHCP) server.


Error; Source: Dhcp Event: 1002

The IP address lease 192.168.1.100 for the Network Card with network address ************ has been denied by the DHCP server 192.168.1.1 (The DHCP Server sent a DHCPNACK message).

Other Errors:

Hi rff123 :)

Things to check...
- the router is on the same subnet mask as the computers.
- both computers have different names
- a firewall on the computer blocking the router.

In any of these cases if any apply, fix the issue then reboot both computers to renew the ip settings.

If they don't renew automatically, go to a command prompt and type the following commands:
ipconfig /release
ipconfig /renew

Hey there MichWas Here,

Thanks for your response.

1. Host names are different.
2. Subnet masks are the same.
3. I have disabled Windows Firewall temporarily. We'll see if the issue still persists.

Also, per a suggestion I have an additional computer set up to run 4 continuous pings, 1 each to the following locations:
1. Router 2. Modem 3. One of my computers 4. Google

The ping to Google times out, while the other 3 don't. Does this info. have any significance?

I would have to agree with YeOldeStonecat on the other site you asked the same question on :)

This is clearly an issue between your PC..and your router. All of these errors are related to your INTERNAL network..your 192.168.1.xxx network...not your WAN interface on the router (your ISP connection).

Check the router to see if you can update the firmware
Update NIC drivers on your computers
Make sure your PCs are clean from malware, rebuild the TCP stack/winsock

Your PCs are failing to obtain an IP address from your DHCP service...which is your routers internal interface. The issue is either your router, and/or your computers.


Posting the same problem on 2 sites can cause issues when trying to fix problems, it can also waste people's time when they can be working on other things instead of helping someone that's already being helped elsewhere.

MichWasHere, Thanks for the heads up regarding posting in 2 sites. This is my first time posting to a forum, so I'm not sure of protocol. Cheers.

After additional troubleshooting that didn't fix the problem, I purchased a new router. Connection is not dropping out. Thanks for all the suggestions.
