Thanks to both wouterv & L&LD for their suggestions. I appreciate the time you are taking to help me.
I am somewhat limited by where I can move the router. With the coax terminating on one wall, and the ethernet on the other wall, I would need to have an ethernet cable run across the room to where the router is. Unless I figured out a way to snake this down inside the wall, it would mean having a visible cable run across the room - something my wife would be very opposed to! I do have the one bedroom upstairs where the two connections are next to each other, and will try to see if there is a marked improvement by moving the router there. Actually, it may make sense to try it in all the upstairs rooms, and if it makes a huge difference, then figure out a solution to neatly move the ethernet connection next to the router so that I can use that to provide internet to the switch in the closet.
In any case, you have given me a lot to think about. Thanks again.
