I am attempting to setup a Linksys WRT54GS with Sprint DSL in North Carolina off a ZyXEL 645M-A1 modem. My Linksys hardware worked fine with Comcast cablemodem and the same PC running Windows XP when we lived in Maryland 6 months ago. Without the router, the direct connection to Sprint's DSL modem works fine here in NC. When I go through the Linksys setup step by step, I get as far as Step 7 and get the error "WRT54GS Setup Wizard: The Router is not able to connect to the Internet. Try turning the cable/DSL Modem OFF and back ON again. Do you want to try again?" Repeated attempts do not yield any connection. I've tried to fix this with the following actions, without success: - Upgraded Linksys firmware to 4.70.6 - Sprint DSL's Setup/Troubleshooting religiously done step by step - Swapped out cable between router and PC - Set modem to PPPoE and set Linksys Setup to PPPoE with my Sprint full username and password. The modem did not connect in the PPPoE mode and only began working again when I returned to the "ENET ENCAP/LLC" setting. - Checked every help forum I could find for solutions. Any ideas?
