My old DSL modem went bad and Verizon sent me a Westell 7500 as a replacement. I tried connecting my DIR-628 as had been previously set up with the old modem, but it doesn't work. I've looked at the Westell User Guide: http://onlinehelp.verizon.net/consumer/bin/pdf/VersaLink7500UserGuide.pdf but it's over my head. Can anyone help me with simple step-by-step instructions?
