I work in a place that is an Internet nightmare. I buy satellite broadband that gives me flaky Internet on the Ethernet port. I use the dsl port to get an intermittent service on one phone line and would like to connect the USB port to another phone line I buy via a modem.
My questions are
1. Will the 2850 switch between the currently working Internet provisions if I do this ie USB when the Dsl and satellite go down etc
2 is there a recommended modem. I guess I need a dsl in and USB A type out in order to connect to the USB port

Thanks for your help
