My friend, your ISP is not the problem. I use SBC dial-up on all the computers I need to run a connection to the Internet outside of the house. If you are connecting with the bull**** software they sent you, you will have problems. Because of SP2 and because of the horrible software. I believe when you made the connection with there software from SBC Dial they let you choose 5 numbers, using your area code? Take those 5 numbers choose one and make a direct connection with one of those, using Windows XP.
Here is what you do:
1. Write down the 5 numbers you chose when you where setting up your SBC connection using there software.
2. Go to start> Control Panel > Internet Options> Click on the Connections Tab.
3. Remove all Dial Connections from the list that you have there from SBC.
4. Also check the line that says "Never Dial a Connection"
5. Click on Setup> Next> Check the first Selection "Connect to the Internet" Then click Next.
6. Click on the Second one "Setup my Connection Manually" Click Next
7. Click on "Connect Using a Dial-up Modem" and Click Next
8. For ISP name you can put anything you want, but for my connections just so it looks official I put SBC Yahoo! Dial. Then click next.
9. For the phone number, put any of the 5 numbers you wrote down. No area code, no spaces. Then click next.
10. For username put your account name. Would go something like this: [email protected]
or whatever server you got your account on. Put your password. Then click on next.
11. Check the box that says "Add a shortcut to this connection on my desktop". Click on finish.
Now your all set to go. Just click on the connection you made on your desktop. Click connect. Your set, you should get anywhere from 40k-54.6k depending on so many variables, I dont want to name. Supposidley SBC sent emails to many members concerning problems with SP2, connection problems etc... Telling you download this update for the software, but there software is garbage anyways... so I hope this fixed your problem. If not dont forget to make sure you check out Start> Control Panel> Phone and Modem Options> Modem Tab> Select your Modem> Click Properties> Select Modem Tab again> On Port settings put it to the max it can go ( Usually 115200 )> Click ok.
