Having internet connection issues on one PC **RESOLVED**

Let me start with the setup. I live in a condo that is pre-wired with Fibre Optic internet from these guys: http://www.novusnow.ca/services/internet.php Great speed, and never any connection issues until yesterday.

The setup for the internet is I have a hub in my storage area where the live internet 'feed' comes in and I just connect the live 'feed' to whatever connection I want to make live, using an ethernet cable; see this diagram: ISPHub

I have a router (this one: Linksys 4-Port Etherfast ) hooked up so that all connections are live and in use (bedroom has Slingbox, Laptop in Living room to watch TV from Slingbox, and my gaming rig in the office). Laptop is on XP Pro and Gaming rig is on Vista Ultimate 64.

The strangest thing is, if I remove my router and feed the live internet into my laptop, it works, but if I do the same thing to my gaming rig, it does not work. 😕 However the NIC is working on my rig because when I plug everything through the router I can see the 198 IP address, which indicates to me the NIC is still working properly.

When I got home yesterday I fired up my rig and there was no connectivity. I have tried the following to no avail (some of this was done while on with tech support from my ISP):

1. All repairs from the networking area of Windows CP (reset IP address etc.).

2. Uninstalled/re-installed the NIC.

3. Disabled all anti-virus and firewalls.

4. Did CMD command : netsh winsock reset catalog

5. Tech support tried to give me a new IP from their end, but is says my PC is not accepting it.

6. Tested all cables to ensure they are working (they are).

Now if you were kind enopugh to read all of this, I throw myself upon you for help! I need to have this up and running by tonight because I want to watch game 1 of the World Series and I do not have a TV, only my Slingbox.

So please, please, if you have any suggestions whatsoever, please let me know. 🙂

I thank everyone in advance for any and all help.

Kind regards,
KT
 
The service might use the NIC address of your Laptop as a form of password.

So when you plug the Laptop it works, but when you plug any other Network device the NIC number is different, and thus does not allow connection.

Try this solution.

Ok, I have printed all of that information and am reading through it. I do not have a modem, but I guess the rest of the information still applies.

I'll give it a shot when I get home, thank you very much!

If anyone has any further ideas/suggestions, please let me know. 🙂

PS: My ISP is stumped by the way. I am waiting for an administrator to get back to me, because the tech support guy has run out of ideas.
 
With the vista computer connected to the router, try pinging the router from cmd prompt (ping <router ip>; probably 192.168.1.1 or something like that. You can check your other computers with ipconfig /all and it should be default gateway. That should tell you if the computer has a functional connection to the router.

If it does have a working connection to the router, do ipconfig /all from cmd prompt and check to see if the default gateway is there. In certain situations Vista can lose that setting. MS has a patch available to fix it.
http://support.microsoft.com/d...t.aspx/kb/933872/en-us

Vista also has a problem getting an IP from some DHCP servers. (which may be the reason you can't get it to work when you connect it directly to your internet line)

I can't say for certain if anything above will help you but it's worth looking into.

Good stuff, thanks. I have already pinged the router and it did pick up the 192.168.1.1 IP address, so the connection to the router is working.

I will take a look at those other options and try them when I get home. :thumbsup:

Ig, the second link resolved one part of my issue, thank you very much! I can now connect my rig to the internet as long as I do it directly (I could not before).

I have tried the other suggestions though and I am still having issues once I put anything through my router. As soon as I try to connect through the router, the internet goes dead. It did give me a new error, saying something was wrong with my DNS, but my ISP says they are trying to send me an IP and my PC says it is going to accept it, but then it doesn't.

All of the lights are green on the router and it appears to be working fine, so I'm not sure what to do.

Anyone? Please??? 🙁

Thanks,
KT
 
What does the dns error say?

This might be it.
http://www.tech-recipes.com/rx...ate_primary_dns_server

You could also try setting the dns servers manually. Try setting to the router's ip or your isp's dns server.

Also trying pinging 64.233.169.104 (one of the ips for www.google.com). If that works, vista isn't getting/setting/connecting dns server correctly. Manually setting it to your isp's dns server should work but who knows.
 
The DNS error is as follows:

There may be a problem with your Domain Name Server (DNS) configuration
Windows failed to find the well known host "www.microsoft.com" using DNS. The server may be down.

I tried the link you gave me, but nothing happens when I clink the link in that post (this one: res://ieframe.dll/dnserror.htm# ). Is there a way to manually disable this TCP setting?

I tried setting everything up manually in my router (Static IP, Gateway, etc..) but for some completely ridiculous reason when I go to save the settings it asks for my username and password again (even thought I have just given it to log in to the routers IP) but it does not accept the username and password, so I cannot save the settings. :frown:

Is it possible my router is just toast? From outside appearances it seems to be working fine (all the appropriate lights are on) but even if I connect just my laptop through it I cannot get a connection to the web. 😕

Thanks for your continued help with this.

Your Your Internet connection is a private arrangement that is s dome through Building.

Did you check with the service provider that the system is allowing for a Router and how to set authentication?

Or at least ask neighbors that use the service if they are using a Router and how it is set.

BTW, when you are connected directly to the Modem!! What is the computer?s IP.
I.e. is it Internet IP address or Private address.

Yeah, I was on with them last night again for about 2 hours. They said it is all ok and they can see my PC as live and every permision appears to be correct. The problem appears to be my PC (when connected to the router) is not accepting an IP address from the ISP.

I think that answers your question, or do I need to ask them something specifically? Please pardon my ignorance, but I am no networking guru as you can probably tell. 🙂

PS: Apparently one other person in my building is having a similar issue and the ISP is making a house call to that person on Friday to see if they can fix it. They would come to my house as well, but I will not be home at that time. If I can't fix it by Friday, hopefully they will learn something from their visit to this other individual that will help me out.

PPS: I find it odd this only happened the day the ISP performed an upgrade. Strange coincidence? I doubt it, but I'm not sure why it would create a problem like this.


Edit: Sorry, just saw your edit. When connected to the router (I assume you mean router and not modem) I get the 192.168.1.1, which is correct. If I connect directly to the Internet I get some 64 address, which again is correct, but it is using the two in concert that seems to cause the problem.

Unfortunately I do not really know any of my neighbours, but as I mentioned above there is one other person in my building with this issue.
 
Honestly I am confused.

When a PC is connected to a Router it gets nothing from the ISP.

At the monment taha you put a Router it isolates the PCs from the Internet, that is the whole idea of a Router.

It is the Router that suppose to obtain a connection from the ISP.

A Routers keep a live connection even if there is No PCs attached to them.

Read the Routers manual, connect to the Router with one of your PCs and check if the Router is configured correctly and if it has a live Internet address on the WAN side.

I am probably not explaining my self properly, I apologize.

I do understand the overall idea of a router and I do believe my router is configured correctly, because I have been using it for months with the same configuration and it has never been an issue until the other day when I first posted.

My router's manual really does not say anything useful, it just shows you how to set it up (with giant pictures), which I have already done.

I have done a hard reset on the router multiple times, to no avail. I have switched all of the cables around and tried single and mutliple connections through the router, just to test. None of it has worked.

In essence I guess the problem is my router is not accepting the IP from my ISP?

I'm sorry if I am getting my terminology or phrasing mixed up, this is somewhat new to me as I never have had problems like this before.

If the Router is Not getting the IP.

There are three options.

1. The Router WAN credentila are Not configured correctly.

2. The Internet Provider has a scheme thta prevent the use of a Router.

3. The Router is Busted.

------

When you are connected directly to the Modem Hub waht ever.

What is the IP that is assigned to the connected computer???

When directly conencted to the internet hub, my PC has a 64.something IP (not at at home right now, so I can't check the whole thing), which I believe is correct.

1. How do I figure this out?

2. I don't think that is the case becaus it was working before and there was no indication from the ISP this would be the issue.

3. I am beginning to think this may be the probelm. If so I am very happy I went with the extra warranty!

Thanks again.

If it is 64.*.*.* that is not a private IP (a good thing).

If it worked before and the ISP did not change its policy then you might need a new Router.

Otherwise, if you can borrow from some one a Router you would be able to solve the puzzle.

Do not know about Canada but if you are looking gor a decent inexpensive Router.

Well that is relatively good news. I have the extended warranty on my router, so the place I bought it will replace the item at full original cost paid.

I've never seen TrendNET in Canada, is there something else better than Linksys I can look for? I have about $60 to spend (I think).

In the interest of closure I will post back to let you everyone know how it went.

Thank you so much for all of the help.

Cheers,
KT
 
Some of these special Internet vendors provide a shared service.

I.e. they have a Router in the Building and every user is logs as LAN users.

When on service like this the user obtains a Private type of IP and does not have a real External IP.

These type of arrangement are many times Big trouble.

In the USA AFIAC the best deal for the $$$ is this.

Circuit City and NewEgg have it for good price.

Well I'm certainly fortunate not to have that setup in my building.

I will take a look for the Buffalo as I have heard nothing but good things about them. :thumbsup:

YAY I finally got it fixed!!!!! 🙂

So I swapped my router for a new one (no charge to me, so no worries) and it still was not working. I did some more digging and I finally found something else to try, and it worked!

All I had to do was open CMD and enter the following:
netsh int tcp set global autotuninglevel=disabled

The console said ok and everything worked after that. Apparently there is an auto-tuning feature in Vista that can sometimes cause issues with certain routers. Fortunately you can disable it. I can't believe it was a Vista issue though, I definitely thought it was my router.

Anyway, thanks again to both Ig and JackMDS for all of the help and suggestions. :thumbsup:
