A little Internet help would be greatly appreciated

[dario]

I'm sure you guys get this type of problem a lot so I apologize for the redundancy. I don't know too much about computers so I'll also apologize for my ignorance because this may be tedious for you.
Finally, since my problem is limiting my access to the Internet I'll also apologize for any lack of communication you get on my part.

In simple terms I cannot connect to the Internet. I am living with two other guys and we have cable Internet but only one of us has the Internet. We're running it through a router (D-Link) and his is the only one that currently has the Internet. At one point we have all had the Internet, but when one has it the other two do not, and the one who has it now has had it the longest and seems to acquire it the easiest.

All three of our computers are running Windows XP. Mine is a Sony VAIO PCVRS630G, the one with the Internet is a Gateway I think, and the third is a no-name brand I think.

I've lived with the third guy and his computer before and we were both connected to the same Internet with another computer via a D-Link router. We did have to reset the router about every 4 hrs because the connection would shut down. I don't know if that is relevant or not. And I think we had DSL.

I've run a diagnostic on the connection and this is what I got:

Connection test passed

This adapter is configured to obtain an IP address automatically. No DHCP Server is present on the network. Windows selected an IP address using Alternate Private IP Addresses

Ping Gateway 0.0.0.0: Failed

No DNS server is available for this connection

No WINS server is available for this connection

Ping Network 169.254.255.255 Failed

I have no idea what any of that means but when trying to repair the Local Area Connection I get this message:

Windows could not finish repairing the problem because the following action cannot be completed: Renewing your IP address.

I also have a "Net Adapter 1394 Connection" located next to the Local Area Connection and when I try to repair it I get:

Windows could not finish repairing the problem because the following action cannot be completed: TCP/IP is not enabled for this connection. Cannot proceed.

Like I said I have no idea what any of this means. I've tried copying numbers down from the computer that has the Internet, but that doesn't work, especially the IP address which is listed on that computer as being something that starts with 72.240 etc., but sometimes when I enter that I get a message stating that my IP address has to be in a range like 123-200 or something like that.

Any help you could give me would be greatly appreciated and thank any or all of you in advance. I'll try to respond to your questions ASAP. Thanks again.

Quick fix usually.

1. Make sure all machines are pulling DHCP Addresses
2. Turn of all machines
3. Make sure router is Assigning DHCP Addresses
4. Reset power to the cable modem (while router has power)
5. Boot up each machine one at a time.

If you are unsure of the current configuration of the router you can reset the current configuration to factory default by holding down the reset button (usually for over 10 seconds)

The router model # is DI-604. How do I find out if all machines are pulling DHCP address? I pretty sure mine isn't because it doesn't have a message saying it is. I tried the ping options but they didn't work. I know I'm not receiving any packets if that helps.

For the computer the Internet works for in the status pane it says that the IP address is being assigned by DHCP, but the IP address is listed as 72.240.101.124 and not one beginning with a 100 #. My IP addresss is listed as starting with 169. Keep the questions coming. I hope I'm helping.

Thanks again for all your responses.

You're assuming the problem is with XP. This is an incorrect assumption.

The problem is in the configuration of the router. It sounds as if it has not been configured at all.

D-Link - what model number?

Click on Start > Run and in the box there type, "cmd" (without the quotes) then, type "ipconfig" (again without the quotes) and hit the Enter key.

Report back with the
IP Address
Subnet Mask
Default Gateway

 

[JRock]

Can you release and renew your IP address?

from command prompt (goto start > run > type "cmd" without the "" and hit enter)

now type "ipconfig -release" without the "" hit enter and wait a few seconds

now type "ipconfig -renew" without the "" hit enter and wait a few seconds

 

[boomerang]

OK, I see you posted the model number of the Router. There are several revisions. Click here and report back what revision you have.

The fact that you have an IP address starting with 169 is all I need to know right now. This is as it should be and is consistent with the fact that you have internet access right now.

JRock, I'm just trying to figure out the IP address of the Router right now. I use Netgear products. Do you know, does D-Link use 192.168.0.1, or 192.168.1.1 or what? He's still going to have to get in to do some configuring even if he resets. At least I do with Netgear Routers.

 

[dario]

On the computer the Internet works:


IP Address: 72.240.101.124
Subnet Mask: 255.255.252.0
Default Gateway: 72.240.100.1

 

[JRock]

You sure you even have a router in place? That looks like that machine is directly connected to the cable modem.

D-Link uses 192.168.0.1

I think I know the problem, You have the modem plugged into a LAN port, put it in the WAN port and reset the router to factory defaults. Should be a ball point pen button you push and hold, but I know that my DLink has something funny where that doesn't alway reset it. Called support, and they told me how, but now I forget.

:thumbsup: Good point Sir!

From that link I gave you, click on the label that is appropriate and there are a number of questions and answers that you should find very helpful.

There is the procedure for resetting the Router.
A procedure for connecting to the web-based interface.
A procedure for connecting using a Cable Modem.

Even a procedure to configure XP correctly to work with the Router.

And lot's of others.

According to what I saw at the D-Link site, a paper clip with the Power ON is the correct procedure, for what it's worth.

All the computers are plugged into the router in a numbered port.
The router is then plugged into the cable modem through the port that is separate from the numbered ones.

However, when we mess around with router/modem/etc. and the Internet goes out for all of us, the guy whose computer gets the Internet goes and plugs his cable direct into the modem for awhile until he gets the Internet back and then plugs it back into the router and it works for him and, but still for noone else.

The link to the router revisions wouldn't open but I checked and it says H/W revision - E3 and F/W revision - 3.51.

A friend of mine has wrote me this email, trying to help me
can it be useful ?


why are you connecting a system directly to the cable modem? that is messing you up. stop doing that!
when he does that, the modem takes his MAC address then assigns an IP from your ISP.
if you connect your router back without powering everything off, it won't be able to get the IP from your ISP.

unplug both the cable modem AND router. power up the cable modem first, then the router. go into the router's configuration page and make sure it is getting the WAN IP from the ISP. then power up your workstations.

Factory reset the router. Make sure the cable modem is plugged into the WAN/Internet port (isolated) as you mentioned you did in the above post. Then starting with the cable modem. Powercycle (unplug the juice for 1 min) the modem. Plug the modem back in, powercycle the router, then reboot each computer. Otherwise call Dlink support. Good luck let us know how it goes.

Edit: your friend via email is right. Cable modems have a habit about learning mac addresses, but doesn't tell me why your roomie pulls a public ip while in the router.

From what i recall down the left handside of dlink routers, should be something labeled WAN. Click that then find the wan status. Make sure you're getting the 72.x.x.x ip on that page.

It sounds like your ISP is giving you a public IP address. If this is the case, you want your router to pull that IP address from the modem, then assign PRIVATE IP addresses to the computers connected to it.

Make sure your router, on the WAN side, is set to retrieve an IP address automatically. Also make sure that the LAN side is configured to dish out IP addresses to clients that connect to it. Refer to documentation on how to verify and/or configure this. You may have to statically assign an IP address of 192.168.0.2, subnet mask 255.255.255.0, on a computer that is connected to the router, then http to 192.168.0.1 to get to the configuration screen.

After you've verified the router config, change the computers IP settings back to DHCP and see if the router assigns it an IP address by doing an "ipconfig" as usual.

If this sounds like a bucket of confusion, you may just want to call tech support. Good luck.
