tearing my hair out error 721

Okay heres the long version so i dont miss any details.

I system restored my year old Sony vaio 3 days ago. And liek every teenager ive long since lost my cds to my hardware (alcatel speedtouch USB modem specifically)
So i hunted down the drivers and installed them. i then installed the update to the drivers to make them as current as possible. I plug the modem in and the DSL line syncs. i put in my username and pass and click connect... the connection hangs and eventually i get error 721 : the remote computer did not respond. so i went in search of error 721 and it lead me to Remove and install TCP/IP and Remove reinstall DUN both of which did no good at all. I knwo the modem is not the problem as i have the same modem and drivers installed on another omputer and it works fine. I have tried reformattign again. copying tcp/ip files from computers that work... nothing... im at a loss.. i dont even knwo which piece of hardware to replace if i need to... am i goign to have to buy a new PC? or a new windows?

No need in my opinion for new hardware or a new PC or a new Windows. Those will give exactly the same errors if you don't install the modem and ADSL software correctly.

I find this link for installing the modem software from CD
http://www.iinet.net.au/support/adslmodems/stusb/install/stusbinst01.html
I don't have the faintest idea, of course, of what you downloaded and installed from the Internet, so it's impossible for me to tell if that was complete and correct. What does Device Manager say about the modem?

Then you don't tell if the ADSL-subscription came with any more software than just the modem driver. "the modem syncs" probably means that it's happy to talk with the modem at the ISP side of the line, but that doesn't say anything about the communication between your computer and the modem. My ADSL uses a NIC, and the modem logs on, so I simply have connection without ever typing in a username/password combination. In fact, using DUN with ADSL doesn't seem very logical to me.

The only reasonable thing to do: do exactly the same as when you initialized the ADSL on this machine a year (or less) ago the first time. If you're sure the modem drivers are OK, better contact your ISP for instructions. Their helpdesk should be able to solve this problem.

Hope this helps.

J0kk3rr,

"i put in my username and pass and click connect..."

This sounds like a dial-up connection. DSL is an always on connection, password/user name are used for account access and e-mail.

First in Device Manager check that all
drivers are installed. Then Try...
Control Panel/Internet Options -> in Connection Tab use "To set up an Internet Connection, click setup" Follow the on screen instructions.

For some reason untill the Internet Setup Wizard is run, Win9x and XP will not recognize the NIC card or TCP/Ip protocals.

Hope this helps and applies
Bill
