I have had FIOS for several years - tv, internet and phone - and recently upgraded to the newest set top box. I'm finding the instructions very confusing. They direct me to set up a router, but I already have a router, so I'm wondering if I can skip that step and other steps related to it and go directly to the part about connecting the box. Does anyone have any insight into this? It's driving me crazy. Thanks in advance! Cathy
