Generally speaking, isp want a direct line from the outside of the house right into the cable modem. You maybe able to move it to another location, assuming the loss is not too great. Meaning no splitters other then the ones the cable provider installs if you have cable tv as well.

so when the installe comes, you tell them where you want the cable modem and they'll probably drill a hole on the external wall to bring in new cable.

test with direct connection to a computer, once that is verified to be working, then you can connect it to your router.
ideally the wireless router is on the main floor, more or less centre of the house to provide best coverage. Whatever you can connect with ethernet use ethernet. Other devices will have to be on wifi. You'll need to find clear channel if you still have 2.4GHz stuff.

so coax from outside - cable modem - wireless router.
