NVIDIA nForce MCP problems

NVIDIA nForce MCP problems

I have a big problem. I'm trying to connect to the internet by using ethernet instead of USB.
I got all the drivers for my ethernet card and everything is looking great.

But then I get this crap about having limited to no connectivity. I try to repair this by clicking "Repair."
After about 5 minutes it says that it cannot fix the problem because it cannot renew my IP address.

I tryed releasing and renewing my IP address by using the IPCONFIG commands. Again, no luck. I got this error message:

" An error occurred while renewing interface Local Area Connection 2 : unable to contact your DHCP server. Request has timed out."

And now I'm here asking for help.
If anyone can help it would be greatly appreciated.

Here's the deal. Around here, PCI network cards on sale are 4.99 or less. Even daily prices are under 9.99. While it would be nice to get your onboard card to work proper if that is the issue, I always pull out a network card and use that to see if this is the issue.

Sometimes you have to bow to the reality that a cheap fix is the way out. Also, a so-so ethernet cable can cause this or a failing port on the router or a router that needs a firmware update. Given today's bargain prices, support seems non-existant.

NVIDIA nForce MCP Network Controller

In reply to: NVIDIA nForce MCP problems

I have had almost exactly the problem you describe. The network controller keeps grabbing an invalid IP address and cannot connect to my broadband ISP (RCN). RCN tech support believes it is a compatability issue with this particular network controller. The PC mfr. (emachines) says they've never heard of such an issue and that I should try another ISP. (Gee, thanks.)

I think I'll go with installing a new network card. Did you try that (as recommended to you back in November)? Did it work?

Me too!!

I'm having the same problem with my ethernet card, I keep getting an incorrect IP address of, are you getting the same incorrect IP? I think the MAC address is having a problem, because it's not showing a Physical Address, it's displaying 00-00-00-00-00-00 for a Physical Address, (which is the MAC address for the ethernet card). If you have found a solution for this problem, could you please share the solution, I'd really appreciate it. The only way I can connect to the internet right now is to have a connection to the ethernet card from a Linksys NR041 router, which I don't like, 'cause I can't send or receive files with friends because of the firewall in the router, and I can't figure out how to disable the firewall in this router... If anyone can be of some help with that, I'd really appreciate that as well. The only reason I can get a connection with the ethernet card from the router, is because the connection is using the MAC address of the router to obtain a valid IP address.

I would appreciate some input on both of these matters, whatever they may be... Happy

I installed my old 3com NIC in the new machine and got a connection. (I think I had the same or similar invalid IP number coming up. It began with 169.) eMachines sent me a generic network interface card (D-Link by Realtek), but it didn't work either. I guess my ISP tech support was right: it's a compatability problem with the cable modem they supplied. If I ever switch ISP's I will try the nvidia controller again. Until then, I'll just stick with what works. So I suggest trying another network card. I've been told Linksys and Netgear usually work with my particular ISP (RCN), but 3com also works. Hope this helps.

Nvidia Nforce network probs

In reply to: Me too!

just to back up the last post. I had intermittant connection problems using this controller always thinking that my ISP was the problem, ringing up having my connection tested... When it was working it was on fire (not literally!), but i became so annoyed with being disconnected every hour or so or not being able to connect at startup, i bought a seperate pci network card. Although noticably slower i haven't had a disconnection or non connection on startup since. So much for onboard controllers!!!

get a router.

Get a router/switch properly solve most of the problems.

Wouldn't this slow my connection down further, runscape?

nVidia nForce Networking (or should it be Notworking!)

In reply to: Nvidia Nforce network probs

Its good to see that other people are seeing the same problem. I am running a ShuttleX 85G - Onboard enet - It works fine when its locked to 10FD, run at anything else and it falls over. Its not the switch (Cisco), its the adapter...
What do nVidia have to say about this I wonder...

disable checksum offload

In reply to: NVIDIA nForce MCP problems

My problem was whenever i tried to receive some big files (more than 500mb) over ftp or lan my network connection completly hang up.
After two clean installs of windows, one visit at the computer retailer etc i found first solution - as told in yours thread - unpluging power suplly from computer.
Today after some extensive search over the web i found the better solution:
- disable chechsum offload (go to device manager, find networking controler, click properties, it is on the advanced tab) - to this moments it is working fine (i just transported 4gb fil from one computer to another)
1. i'm not sure this will solve yours problems but i'm searching web for solutions of my problems for one week, and found there many different problems (as yours) which can be solved by unpluging power suplly. As I think this problems are not just with nvidia4 chipset but also with 3 and maybe even some other chipset
2. if you need more information about checksum offload use google and you will find some microsoft articles about it and many threads
