My current setup is an iBurst modem plugged into the ethernet port of my WRT54Gv5 router and connecting via PPPoE to my provider. Works a charm. I will however be changing from wireless to ADSL shortly. The ADSL provider will be providing me with this Billion modem. So it looks like the ADSL line will feed into the modem, it will do the connecting and it can share the connection with my wireless devices. I assume that the linksys won't be able to take the DSL cable? If not, what other uses can I get for the router?
