Trying to decide which router to use. I have some understanding, but since I joined xFinity I've had my XFi Router in Bridge Mode to my R6400 Nighthawk. I'm mainly curious if I'm losing or gaining anything here in terms of speed/coverage. I've tried browsing the interwebs, but can't seem to find anything specific in reference to my router. Any of you guru's out there care to help me make the right call?
