New electronics equipment can be smelly indeed. Depends highly on the soldering process and the (over) use of flux most of the time. Routers usually don't have cooling fans to get rid of those smells quickly. Suggest to place a fan in front of the ventilation openings to blow or suck away the left-over evaporating molecules. Our new "talking" rice cooker is also smelly. Happily these things have cooling fans ;)

To Bug or not Debug that is the Q.
