Cannot Connect to the Internet Using a New D-Link DSL-2640B

I recently purchased a D-Link DSL-2640B DSL modem/router to replace my Speedstream 5100 modem currently in use with my AT&T DSL service. I used the browser based configuration software to setup the new modem/router and even tried the recommended VCI/VPI #'s to connect to the internet, all to no avail. The little computer icons at the bottom of my computer screen say that I have a connection, but when I open any web browser, it says there is NO connection. I have been on the phone with D-Link tech as well as AT&T tech, all without results. I use Windows XP SP3 with onboard intergrated LAN on my desktop. I understand that I am not the only person who has encountered this issue. Please, ANY help will be GREATLY appreciated!!

I'm having problems tring to connect to ATT HS DSL, flashing green light but can not connect to internet, what settings on DSL-2640B do I need???


If you connect the computer directly to the modem, does it work?
If that works then the modem is working.
Now connect the computer to the router and the modem to the router.
You will need to open the set up page of the router to check the settings of the router.
You can set up the router without the CD also.
It is very easy.
