    good news. Go buy a router, not a wireless card.  If the routers LAN ports are failed, how long can you trust the wifi portion?

    All of my posts are either intelligent, thought provoking, funny, satirical, sarcastic or intentionally disrespectful. Take your pick.

    I get banned in the forums for games I love, so lets see if I do better in the forums for games I hate.

    I enjoy the serenity of not caring what your opinion is.

    I don't hate much, but I hate Apple© with a passion. If Steve Jobs was alive, I would punch him in the face.

    There's a lot of bad advice in this thread from people who don't know much about networking, but had a "solution" work for them.  Unfortuantely, networks are a very complex thing and a lot of different issues can cause very similar symptoms.

     

    You've done a lot so far and I'm not sure where you're at.  Start at the basics, please.  Go to Control Panel, Network and Sharing Center.  On the left, click Change Adapter Settings.  What do you see there?  You should have a list of your network cards or wireless devices.

     

    Assuming you have one that says "Local Area Connection", right-click and select properties.  Uncheck TCP/IPv6 if it is checked, then select TCP/IPv4 and click properties.  What do you see on that window?  Close everything, accepting the IPv6 change, and report what you saw.

     

    I'm going to stop there.  Once we know more about your configuration and existence of a network card and drivers, we should be able to troubleshoot more.

    Please don't switch to wireless as suggested by another post.  It has many flaws which hinder online gaming.  It is convenient for an office environment where you browse the internet and send files, but not for time-critical applications like gaming.

    If your NIC ends up being bad, you can buy a cheap one and install it in your PCI slot if you have one free.  Alternatively, they make USB NICs, but I have never tried to use one.

    I wouldn't normaly respond to this, but seeing how you call others out:

    You mean you give bad adivce in this thread?

    There is no update for vista that would auto turn on ipv6, and I'm gona guess since the OP doesn't know "unidentified network" and "there may be a problem with your modem and router" are generic error messages for " i can't ping out", then I'm going to make the assumtion he wouldn't have turned that on himself even messing around. That's about the last thing he should check, especially with the other info given.  Also, his "network" consists of his router and his pcs/phone/tablets in the home, how  complicated is that?

    All of his other pcs can get online except the wired one, that takes out  half the troubleshooting right there.

    Again that leaves these steps:

    Uninstall the nic and rebbot (OP has done)

    Hook another device to the port in the router that the pc that can't get online was/is in. Can that pc get online using the wired NIC? If no, it's you router. If yes:

    You COULD reinstall the OS, which may or may not work, and I'm only saying that cuz it's vista and I've had cases of that. But I wouldn't becuase of the time it takes to redownload all your games and stuff, and because it sucks if you do that and that isn't the issue.

    I posted a link above from Tiger for a $15 nic. 2 pops into a PCI slot, run the disc. Disable the old card. Done, done, and done. You are online.

    It could be the router has conked out on you.Over the year's I've had 2 router's go out.The last one was about 6-8 month's ago and it gave me a message like the one you received.Could be what it is.

    You think so? I can still connect wirelessly to it. Maybe I should just invest in an adapter?

     

    Reading back through all your post's,I'd try hooking your pc ethernet cable to a different out on the router and see if that work's.

    I've tried that as well. Still nothing 

    Ok so from what I've read you are able to get online wireless with any devicee in the home, but the pc wont connect wired from a router. Well If you have done the basic uninstall your nic and reboot, which it appears that you have, then there really are 2 options. Hook the ethernet directly from your pc to modem, reset the modem. Note if you have VoIP through your isp your modem may have a beattery that would need top be removed before it will poer off. Most isp require this to reset the arp table because only 1 public IP at a time in short. If it connects your router is screwed for its wired portion. If not, go but a $15 dollar nic and throw it in a pci slot and done. 

    Also, that looks like vista. This could also not be helping.

    Edit: Spelling

    This worked! It's a good temporary fix until I can go out and buy a wireless card for my desktop, or even a new router. I don't think it will cause too many problems for gaming considering my computer is right next to the router. 

    Awesome! I'm glad that I could help.

    What you are going to need to do is start with the basics.

     

    1: Verify your cable; 

    • test the cable with an alternate computer or notebook. (make sure to turn off the wireless on the notebook before testing LAN)
    • If you have no internet on a cable with your notebook, then switch out the patch cable.
    • If that doesn't work then switch ports.
    • If that doesn't work then reset or replace your router.

    2: If it does work with your notebook and your cable / router is functioning then;

    • check / renew your IP address
      • click start > type cmd in search box > right click cmd.exe in the search results and choose run as administrator
      • Type ipconfig /all in the command prompt > scroll up until you see 'local area connection' and take note of your IPv4 Address, and your Default Gateway.
      • type ipconfig /release > make sure no error messages prompt, if they do post the error msg. Repeat the previous step to confirm your IPv4 address is now 0.0.0.0
      • type ipconfig /renew > again watch for errors.
      • type ipconfig /all > review the local area connection IPv4 and gateway. They should be back to 192.168.1.??? or something similar.
    • Check your proxy settings
      • go to Control Panel > Internet Options > connections tab > LAN settings
      • Make sure that none of the checkboxes have checkmarks.
     
    I'll look back in a bit, and see what your results are before I write a book

    Proxy issues will show the pc is online and can ping out but cant display websites. His is not getting an ip at all/ or getting one alread in use by another device.

    Edit: looks like the issue is resolved now, wired nic for router went bad I think he said it was. I'm out have a good night everyone.

     I was thinking there could be proxy problems conflicting with DNS leaving the network as local only, but you are right.

    Advice like reinstalling the OS, removing the drivers, switching to wireless, and taking a chainsaw to a working-but-suddenly-bad configuration is bad advice for this kind of issue.  Also, cables don't suddenly go bad unless someone damages them physically.  There are only a few things that can cause a network connection to suddenly stop working.  Most of the advice suggested doing things which are mid-way through a normal troubleshooting process, or create more work than they are worth.

    A normal troubleshooting process starts with basic functionality and works your way up to higher levels of functions.  Since hardware is difficult to troubleshoot without spares, there is little you can do but assume the NIC is working when you start troubleshooting.  As you work your way through the process, indications of a bad NIC will be obvious.  Checking to make sure the computer is getting a proper IP address can tell a lot about the network.  The next steps would be to see how far the computer is able to ping using IP addresses.  If the computer is able to ping, but not resolve DNS queries, that is also easy to fix without spending more money.

    One suggestion even suggested changing proxy settings.  Home users shouldn't have to mess with those unless you have a very unusual setup, or connect through a VPN, which is also unusual.

    In this case, it appeared the router needed a reboot, but the OP wasn't very specific about what worked.  Spending money on a new router or NIC would have been silly if that's all they needed to do.

    From what I'm reading,Mcpickle suggested bypassing the router and connect the pc directly to the modem,he did and it worked.The router is toast,so he either need's a router or a wifi adapter for his pc,as the wireless part of the router does work,but not the wired part.

    he suggested in post 21.
