I live in cinder block house so wifi does not work very well. In my basement, the isp has put my modem, from there I have a 6 foot cat6 cable to my router,that works perfect in basement, can I take another cat6 cable from my basement router and run it upstairs to my main floor and put another router there to get wifi on my floor. I have completed the cat6 wire job, now wondering if I should put a second router in on my main floor or try a mesh unit or something else? TYI
