Connect the filters to your phones lines, one filter is required for each line you have. Plug the modem cable into one of the filters then into the speedtouch modem. Don't plug your speedtouch modem into your computer usb port yet. Load the drivers first, then plug the modem in. Wanadoo should have emailed you a user name and password, enter those when first connecting to the net. Wanadoo says it takes about 10 days to activate your line, mine only took 3 days. You'll know when your line is activated because you'll have 2 solid green lights on your speedtouch modem.
Hope this helps you out.
