I think I do know what goes where.
You were trying to explain to the poster at rather a detailed level. When doing that you need to get the detail right. XRaySpex asked the right question. I expect the answer to that will tell us what the OP means

.
Even now, you use the term �router box�. That too may or may not include a modem and in domestic models usually an Ethernet switch.
My ISP-supplied router has only one wire going into it, and that is the power cable. It does have a single ethernet port, to which I occasionally connect a laptop. Normally my main laptop, this iPad and my phone connect wirelessly to the internet through it.
How does my ISP provide my broadband connection? How would you describe it?
My phone contains, amongst other things, both a router and a WAP. I expect yours does as well. I think I�ll start calling it a CD. After all, does play music, and doesn�t even need a hole in the middle for a spindle. Technology really has moved on. Or not. In the 20th century �wireless� was a noun.
I think we digress. Other than the first two paragraphs I�m just having a bit of fun in all that, whilst pointing out that what we call things often bears little relation to what they are or do. I hope you will take it that way, now I point it out.
My broadband basic info/help site -
www.robertos.me.uk. Domains, site and mail hosting -

Connection - Three 4G, tbb tests normally 35-45Mpbs down, 65Mbps off-peak, 9-24 up.
