That's my preference as well. Keep the router simple, don't put a transmitter near the sensitive bits to cause interference with the CPU, ethernet, or USB bits

I want my AP to be dumb and do nothing besides connect ethernet to wifi clients. That way when you need more coverage you add APs, newer WIFI upgrade only the APs, etc.
