I presume so however I can't be positive as each DSL modem is a bit different. I know that once the DSL modem is correctly bridged and the 655 as the PPPoE info, power off both, then power ON the modem, then power ON the 655, usually you should get internet if the Blue globe lights up on the 655. If it doesn't turn from Amber to Blue, something isn't right on the modem or the PPPoE info isn't right on the 655 router. I would ask for level 2 support from your ISP. Might do a search on the web and see if you can pull up any info on bridging that model modem from other forums if you can't get any help from your ISP.
