I am wanting to use a Linksys BEFW11S4 ADSL wireless HUB/Router. It also requires that I have an ADSL modem. The problem is that I can only find USB modems. Is there a manufacturer that produces ADSL modems with a Ethernet connector, or a piece of hardware which will take the USB B (flat connector) from the USB Modem and output to an RJ45 Ethernet connector. I can only find things that go the other way.
