I have my own Linksys router for a home network, and got DSL service with Earthlink. Per default settings, the router is configured with DHCP, IP assigned by server, not static. The Earthlink setup information I got is intended for one computer only, not connection through a router (their "home network" service with a router I don't need and tech support is another $8 a month), and they say to use the DHCP/Automatic setting for TCP/IP. However, I notice in Earthlink's modem diagnostics that there are pass/fail lines for "PPPoE server connection" and session (that are "pass" when the router is connected).
Should I configure the router for PPPoE? Seems to work okay as is, though I have a problem with voice phone use causing the DSL connection to fail (getting a whole-house splitter).
Obviously, I don't understand the difference between DHCP and PPPoE, or even if they are used together, or are alternatives. Sorry for my ignorance!
Thanks for any advice,
