I had no clue McAfee was built into my router as there is no indication of it that I can see. I got the router for free from a mail in rebate from Toshiba.

Yes I used the same cable to connect it to the PC when I tested, if I recall correctly. And I plugged the modem into the ethernet port on my computer.
The status page on my router says this for the wan port: WAN:11M/54M
I didn't even know that there was such a full manual for my router, I thought there was just the very basic manual that came with it.
