Old "Limited or No Connectivity" Problem.

[DianaMaclay]

Hi! I am new at this, so please bear with me if I don't understand very clearly.

Yesterday I had a problem with my PC (who runs on a x64 operating system) I was trying to play GTA on it when it suddenly froze and wouldn't let me do anything, so I punched the restart button. The BIOS screen went OK, but just before the "Windows XP is loading" screen... well, the already mentioned screen went black and never got to the already mentioned loading screen, it just went black. I checked the LED to see if there was any activity on the HDD and there was none.

But this, is not my problem. I already managed to fix that one by entering the recovery console and by rewriting the boot files (or something like that, I can't remember) with the "fixmbr" command.

This absolutely fixed my problem, cause right after that I restarted and Windows worked just fine.

Now, the real problem.

When I tried to use Internet Explorer I got the usual message saying that there is no connection. So I did what natural comes to me, and went to Control Panel to open the Network Connections. I'll sum this up: A day has passed with me searching through forums and forums with never ending similar problems, and I haven't found a solution.

I've already tried the Winsockfix pogram and nothing hppened.
I've already tried this: netsh winsock reset catalog and netsh int ip reset reset.log and nothing happened.

I also should state that I have two desktops connected to the same modem. One PC is connected via USB, and the other (the one with the problem) is connected via Ethernet. I've already tried to conect the "good" PC to internet trough the Ethernet cable, and it worked just fine, so it is not the cable. And I can't conect the "bad" PC to internet via USB cause there are no drivers for my modem that works on the x64 Operating System, and that is why I have to fix this problem. I keep getting the "Limited or no connectivity" warning globe. And it also sys that the network did not assign a network address. Obviously, trying to renew the IP Address does squat.
I've already tried to assign manually an IP address (the same one that my "good" PC has) but obviously, it said that there was a conflict there.

I thank in advance for reading this post, but please, help me solve this problem.

Long days and pleasant nights.

Also, please give an exact description of your problem symptoms, including the exact text of any error messages.


I'd also like to see this from the failing machine.

Start, Run, CMD to open a command prompt:

Type the following command:

Hi again, and first of all,thank for the help.

System:
Microsoft Windows XP
Professional x64 Edition
Version 2003
Service Pack 2

Computer:
AMD Athlon 64 X2 Dual
Core Processor 4000+
2.11 GHz, 960 of RAM
NVIDIA GeForce 6100 nForce 405

Motherboard:
Gigabyte S Series GA-M61-SME-S2
microATX
Socket AM2
Intel® P35 Express / Intel® ICH9R

Modem:
WebStar by Scientific Atlanta
DPC2100 SERIES
(No Router)

Network Adapters:
1394 Net Adapter
NVIDIA nForce Networking Controller

Connection Type:
Wired

The Symptoms:
Like I said, right ater the first issue, I entered Windows and the connection was gone. No message or Warning Globe at first, just no webpage could be opened and none of my P2P software (uTorrent, Limewire) would be able to connect. Then I opened the "Status" window of "Local Area Connection NVIDIA nForce Networking Controller" which by the way said it was connected. I hit the "Support" TAB in this window. Here the connection status and details were these:

Physical Address: 00-1A-4D-93-AD-EE
IP Address: 10.108.78.46
Subnet Mask: 255.255.192.0
Default Gateway: 10.108.64.1
DHCP Server: 10.0.104.129
Lease Obtained: 09/10/2007 02:39:15 p.m.
Lease Expires: 09/10/2007 10:39:15 p.m.
DNS Servers: 10.0.104.129, 10.0.104.135
WINS Server:

And I noticed that the message in here was: "Windows did not detect problems with this connection, if you cannot connect, click Repair" and so I did. It said that it was trying to renew the IP Address and when it finished it said: "Windows could not finish repairing the problem because the following action cannot not be completed: Renewing your IP Address" So I closed this window and then I disabled and enabled the connection.

Here was when the Warning Globe appeared: "This connection has Limited or No Connectivity. You might not be able to access the internet or some network resources. For more information, click this message." and agaian, I did so.

This was the message from the status window which opened: "Limited or No Connectivity: This connection has Limited or No Connectivity. You might not be able to access the internet or some network resources. This problem ocurred because the network did not assign a network address to the computer."

From here on, it appeared a yellowed warning (!) on the connection status, which dissapears whenever I restart the PC. But still won't let me connect.

That is pretty much what happens. Here it is the IPCONFIG /ALL log or whatever.

I think that is all of what you asked. I hope this can help to find whatever s-h-i-t is going on with my PC.

And thank you so much for any help you can provide.

Oh, and please, for the love of God (to all who reads this thread), don't use my information to hack in to my computer or try to f-u-c-k me over. It is quite bad enough as it is already.

Long Days and Pleasant Nights.

First off, please lose the profanity, even spaced out, that's not necessary to express yourself and work your problem. There is nothing you've posted that will help anyone hack your network.

I'm somewhat confused, since that modem is a plain DOCSIS compliant cable modem, yet you have a private IP address as if you were connected to a router or other local network. You have obtained a valid IP address as well as the rest of the configuration, that looks normal.

What version and patch level of Windows is this?

[DianaMaclay]

Fine, I'll lose the profanity. And thanks for telling me that I'm not exposed or anything like that, it's just that I noticed some posts where users don't post some number of their IP Addresses.

That said...

I do not know what you mean about the version of the patch level, I tried to post everything I could find of my software, so if you could tell me where I could find the info you want, I'll look in to it.

Oh, and by the way, yesterday the other PC (the one with the internet) had the same problem. But I just disconnect and re connect the modem, and it fixed itself. However, the other one is still having the same problem.

Thanks.

[johnwill]

What makes you think you can use two computers on that modem at the same time?

[DianaMaclay]

Well. I saw two ports. And I said... Well, what the hell, let's try! And it worked for about two weeks.

What everyone (not just this forum) seems to keep forgeting, is that it stopped working after my problem with Windows. Now look, I'm no expert here (obviously) but if the internet was working perfectly just before Windows got crazy, and right after I fixed it the internet was gone... It sounds like it had somethiong to do with it. But what do I know?

Anyway, thanks for all the help.

[johnwill]

Most ISP's restrict you to a single public IP address. I've seen many instances where someone could connect with multiple machines for a period, then the ISP realized that it was happening and slaps the restriction on.

I also still don't understand what kind of ISP this is connected to, since I see a private IP address coming through to a plain modem with no NAT layer. Do you live in a large building or is this some kind of commercial ISP?

[DianaMaclay]

I do live in a large building, but I don't understand how that may affect. I also don't understand what is happening then, cause, according to your theory about not being able to connect two computers to a same modem, then I should be able to connect the other PC (the one I'm having trubles with) by just connecting that one, and leaving the other one without internet. However, that won't work either and I still don't know how that can be, cause I've already tried that a lot of times.

Still, I very much appreciate your help, and I hope that you could help me find a solution before I try to format the whole thing.

Thanks.

[johnwill]

I still believe that you're probably only going to get a single IP address unless you install a broadband router.

If you have a machine that never connects, even after power cycling the modem, that's a different issue, that's not what you first said.

If you have a non-working machine, please disconnect the other machine from the modem, power cycle the modem, reboot the machine, and then post another IPCONFIG /ALL display.
