Therein lies an issue. I cannot run a cable to the second floor from the first floor for number of reasons:
(1) I would have to run the cable through finished walls and ceilings which I am not comfortable doing; and
(2) the location of the router on the first floor is directly above the location of the switch in the basement (unfinished side of the basement so its really easy for me to run cables from the basement to the first floor directly above), but the PCs on the second floor are on the completely opposite side of the house.
This would really require a substantial in-wall wiring throughout the house. Sometimes, I really wonder how much it would cost to wire the whole house.
When we finished the basement, I did have the foresight to run 2x ethernet cables from the basement to the first floor on the opposite side of the house. I could possibly connect the router directly to my Linksys WAP54G, but the WAP54G would remain on the first floor. Otherwise, I can take the WAP54G access point to the 2nd floor, but it would be a wireless repeater.
