I have a cable modem. It was connected to our computers through a linksys router. Suddenly I was unable to connect to the internet. After much trouble shooting with the cable company here's our findings.

I removed the linksys router from the equation and connected the cable modem directly to my desktop computer, which gets a gateway assigned and gets returned replies when pinged. However it will not ping any named site (example: ping www.yahoo.com). I replaced the cable. Same result. Uninstalled and reinstalled the ethernet card. All this was done with proper sequencing of power cycling the cable modem and rebooting the computer.

I connected the cable modem directly to my laptop and it connects just fine.

I have no idea where to go from here. Does this mean my ethernet card is bad? Is there a way I can test my ethernet card to prove it's bad? I have Windows XP SP2 and when looking at network connections it says Local Area Connection is connected. Earlier when the Internet Connection icon would pop up it would show as disabled. I would click to enable and it would say connecting, connected but would continue to say 'disabled'. I don't even see the icon for it anymore.

At first today I thought it might have been a virus issue or something as I remember last night that while I was typing something a little window popped up about the time I hit enter and immediately disappeared. At least I think that happened. It was so fast I can't swear to it. But I was still online for awhile after that with no problems and then I shut it down for the night. No problem until I turned it back on today. Anyway, I ran ewido suite, and my virus program (PCCillin) and it didn't find anything.

Any help would be appreciated. Thanks!

Since you can ping the router, it sounds like you network card is likely ok.

WINSOCK2 FIX
=============
If you can't access the Internet with programs like IE, Outlook Express, or other web browsers, you may have corrupted Winsock entries.

To Remove the existing winsock2 registry entries (regardless of the OS) run:
http://www.onecomputerguy.com/reg/xp_del_winsock.reg

To add WindowsXP clean entries back in again, run:
http://www.onecomputerguy.com/reg/xp_winsock.reg

WINDOWSXP with SP2

There is a new command you can run with SP2 which will reset the Winsock2 registry entries back to their default setting:
netsh winsock reset catalog

TCP/IP RESET
=============
If you need to reset the TCP/IP protocol stack with XP you need to run a small script:

netsh int ip reset [ log_file_name ]

the log_file_name needs to be specified.
e.g. - netsh int ip reset ip_reset.txt

Are these links to downloadable files? I mean can I just save them and put them on a floppy or something? I can't connect so I can't execute the links from my desktop computer, which is the one with the problem. I'm afraid to try and do it from my laptop since it's the only computer I have that can connect now.

[Bob Cerelli]

Yes, they are just simple registry files. One to erase the old entries and another to put back in clean ones. They'll easily fit on even a floppy disk.

Just run them in order and then reboot.

Or since ou have SP2 run "netsh winsock reset catalog"

assign a gateway, perhaps something isn't correct in the way you've got it configured.

i have everything behind the router including the router obtaining the ip addresses automatically in tcp/ip properties.

[Bob Cerelli]

Start / Run / CD

IPCONFIG /all

Make sure the IP information (IP address, subnet mask, gateway and DNS) are correct.

Then from the same prompt try some basic PING tests:

Ping 199.181.164.1 - If you don't get a reply, it could either be the Winsock problem as noted earlier or the gateway is not correct. It should be the same as your router.

Ping www.yahoo.com - If the first ping work and this one didn't it is likely a problem with DNS. Sometimes I've needed to set it to be the actual DNS servers your ISP uses rather than the router itself.

OK, I hope I did this right. I opened a DOS window and ran: netsh winsock reset catalog. Then I rebooted as it instructed. Then I ran: netsh int ip reset ipreset.txt and rebooted. A side note, the ipreset.txt was empty. Then I ran the routine of connecting and recycling the cable modem. I can still ping my gateway but nothing with a name and can't connect using firefox or IE. Responding to last two posts:

Bob:
How do I know the IP info is correct. I can ping the gateway, but still can't ping anything using the name. How would I set it to be the actual DNS servers my ISP uses? BTW - I disconnected the router. I actually tried to reconnect it but when I do that even this laptop will connect, no matter how many time I have recycled the cable modem power and rebooted the laptop, so I disconnected it again.

BearOne2:
How do I assign a gateway? While I do software support and some tech support for a living, this stuff is a bit beyond me. Please treat me like a dummy, OK? As I sure feel like one! LOL!

Any by the way, I want you both to know how much I appreciate your help. This forum is definitely getting a financial donation for me because you guys are such good guys to do this stuff for us.

OK, thanks - While I'm waiting for your replies I'll go to my cable company and see if I can find the servers they use for their DNS.

[Bob Cerelli]

Can you post the information from running IPCONFIG /ALL?
Did you try pinging by an IP address?

[TerryNet]

Nancy, do ipconfig /all in a command window on your working laptop. That will show you what you want your desktop to look like.

If you post the ipconfig /all from both computers, it would give Bob a direction in which to go.

One easy way to post:
ipconfig /all >c:\ipconfig.txt

That will put the results into a text file (assuming C is your harddrive) that you can then copy and paste.

i recommend obtaining the ip address automatically in network connections/tcp/ip properties.

if you do that everything is done for you.

I thank EVERYONE for their help, but this problem has mysteriously resolved itself. In the course of setting all the DNS servers, gateway etc. manually and then removing it all, I am suddenly able to connect to the internet. I really wish I knew what the problem was, but I guess I'll have to be satisfied with the fact that it's gone. But, as always, you are all great for offering so much help.
