|I have a pre-existing hole for a wire already drilled into the floor above the WAP. would it be possible to replace the WAP with another router, run a cable through the floor into my first floor, then set the WAP up there?|
Yes, this is possible.
Alternatively, you could run a new cable through both floors and just put the WAP on the 2nd floor. This would eliminate the need to purchase a second router.
If you do go with the two router model, you'll want to click on my name above in my response and read my "how-to" guide titled, "Add a Second Router to your LAN"
You'll want to use the single subnet scenario where you connect the two routers "LAN port to LAN port"
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
