SBC Yahoo DSL + Speed Stream 5100 + won't connect to my Win XP Pro - won't detect it

Hi everyone. I am having a very weird problem

First some quick background info.

1.  Have a windows xp pro machine and recently came off of using a cable modem to go to dsl (had a location change).  I am using SBC Yahoo! DSL.  For some reason, when I get all the cords connected and I try to access the modem ( I get the standard "Internet Explorer cannot open the search page".  

What is weird is that I plugged everything into my fiances Win 98 machine and I was able to access that ip address of the modem and get her computer up and running, but not mine.  

Can you think of any settings that I might have enabled that would prevent my NIC from talking to the modem.  I originally had an INTEL PRO /100 VE or something.  That wouldn't work, so I put in my linksys 10/100 and that also doesn't work.

yes, I disabled the Intel one before using the Linksys.

I do not have any firewall software installed.

Can you think of anything that would be causing this issue.

Sounds to me like you are not getting the correct IP config from your DHCP (modem/router)..

Open a Command Shell and run ipconfig...

Start > Run > cmd (ok)

Then type in:

ipconfig /all > ip.txt

This should put the ipconfig on your desktop in a text file...  Copy it here for us to look at..

just to clarify, that is from my fiances windows 98 machine, the one that has an active connection.

I have tried releasing and then renewing the ip on my xp machine, but then when I try to renew it, it says an error about a socket or somthing.  I have tried doing a "repair" on it in network connections and that gives me back an error.  Something is blocking it and I can't figure it out. argh!

Ok, then this is from the working computer..  Notice the Default Gateway:   this should be the address you type in to get into the modem/router..

Regarding your XP box..  If you cannot get it to reset, then try this utility:

Winsock Fix

If it still does not repair the Network Stack, then uninstall your NIC, delete it from Device Manager, and reinstall it...  Make sure you have the correct drivers installed also..  (although XP usually takes care of this for you...)

What does concern me though, is that your 98 box is receiving a public address, and not a private one in the range of 192.168.x.x / 24.......   I am not familiar with that specific modem/router, although the standards are the same...  If it is actually doing routing, then it should be giving out a private address for your internal network.....   hmmm

no its not a router.  I do have a router though, but i wanted to get connected first and then fiddle with it.  

to access the modem though, I type in  I just type that into IE url box and I access the GUI from there.  I should be able to do the same thing on my xp box.  

The Intel NIC came preinstalled on my DELL XPS machine and I haven't tried removing it because its behind a special casing.  however, I did install a Linksys NIC 10/100 and I get the same message as the Intel one, which leads me to believe there is a configuration on my machine that is preventing the connection.

Interesting..  I have worked on many different types of DSL modems and routers, and I have never seen one accessed via anything other than the default gateway...  Personally, I would throw the router on there and see if you can both connect to it..  In other words, connect your XP box to the router and ping its address, or just try entering into the router's GUI.  This will tell us immediately if it is a problem with your system, or if it is the modem..

when you say "default" gateway, are you referring to ?

I don't know why the problem would exist with my modem if it works on my fiances windows 98 machine.

I will try what you said though.

Yes..  the Default Gateway is the ip address of the interface that you go through to get out of your LAN to the internet...  On a normal LAN, you use a private address such as the 192.168.x.x for all your internal clients, and the default gateway is usually 192.168.x.1    Then the router NATs or routes the internal address to the external address, which in your case is

This is why I don't understand how you can get to the modem with the private address, which from what I see is not even existing in your IP structure..   hmmmm

I posted this over at DSL Forums. It might make more sense.


Let me clarify so we are all on the same page.

Computer #2 (Windows XP PRO) -
Originally hooked up the Speed Stream modem and installed the SBC Software. Well, almost installed because part of the installation process is to communicate with the modem so you can go through the registration process. That didn't work, because it wouldn't detect the modem. So I thought. So I gave them a call. Then I thought, maybe its my Intel Pro 100 NIC card. I had a Linksys 10/100 in a storage box, so I unpacked it and installed it. I disabled my Intel NIC and tried all the same processes with the Linksys. Still, no help. While on the phone with the SBC Customer Support, I said, "You know what, let me try hooking the modem up to my fiances computer (Windows 98) and see what happens, this way we can figure out if its the modem or my computer.

So I connect everything to Computer #1 (Win 98).
However, I DIDN'T install the software. Apparently, going through in the address bar is the same as bypassing the installation of the software, so that is what I did. I accessed the GUI screen of the modem when I did this and actually went through the whole registration process. That is the only reason I am able to post online is because I am on my fiances Windows 98 machine.

The reason i hooked up the router (which is the only thing I hooked up to Computer #2) because I wanted to at least see if I could access that. The modem is not connected to computer #2 when I have the router hooked up for now. For me to access my Netgear router, I have to type in In this case, I cannot access the router either. This is weird since I used to be on a cable modem 3 weeks ago and never had a problem. Then I moved to my apartment and didn't get my dsl access until 4 days ago. In the last 2 weeks, however, I installed AOL 9.0 optimized just so I could get on the internet. I actually had problems connecting with that through dialup. So I don't know if my computer expects to be seeing a cable modem connection or if it doesn't matter.

I hope I gave you the downlow on my situation.


The modem has the address of for administrative purposes. Mostly for registering the user and checking speeds and such.  Its not suppose to act as a router or firewall, but I think I know what your saying by not making sense.  I don't know what to tell you on that situation.

this file did it!

I recently had a virus (bloodhound exploit) or something of that nature where it messed with my hosts file and some other stuff. I may have accidently damaged it or something, but I backed up my reg and ran that prog and sure enough, my computer now catches the modem

My next step is seeing how a dsl modem, which has 1 ethernet port and 1 dsl/internet port can work with my netgear router.

I can't plug the internet port of the modem into the router because the ends don't match, unlike a cable modem.  So do I attach an ethernet cable from the ethernet port of the modem into the internet port of the router, or 1 of the 4 ethernet ports of the router?

Correct..  You should use a piece of Cat5 cable and run it from the DSL modem Lan port to your Wan interface of the Router...   You may need to further configure your router for the specific flavor of DSL that you are using (such as PPPoE or PPPoA) but that should be relatively simple and done in the router's interface..

Glad to see the Winsock Fix did the trick...  Kinda thought that may be your problem...:)

dumb question, but LAN ports are the 4 ports on the router for other computers and the WAN is the internet port, correct?

Yes, I will have to configure the PPPoE.

*grin*  there is no dumb question, as you well know..

Correct..  Lan ports are internal (Local Area Network) and WAN is the internet (Wide Area Network)..

PPPoE is the type of authentication that your DSL ISP requires..  This may already be setup on your DSL Modem, but many times you must manually set it up in the router..  For instance, on my 2Wire DSL modem/router (which is a high end commercial modem that includes 802.11g wireless) everything is done within the modem, but I think that you will configure yours in your router..  Easy to do, and should be in the general setup area..

Thanks, and hope all this has helped..
