Do you think it would be problematic for my Wifi signal to have my router in the middle of my house on top of a shelf and in between an UPS, a coiled Ethernet cable (connected to the router) and a basket (all just inches apart) ?

Probably not. The basket is irrelevant, so is the Ethernet cable (there is not enough current to make a big difference). There are so many unknown factors that only testing will show how good it will work. (Keep in mind that 2.4 GHz has more range than 5ghz)
