Router reset: My download speed has recently been reduced by more than half when I use my Netgear R7800 Nighthawk router as opposed to bypassing the router @ direct connect to the modem. The problem started very close to when I got a new laptop (Dell Inspiron 15-7577). The router is positioned no more than 15 ft. from where I keep the PC & there are no obstructions. I have decided to reset the router to factory & start from scratch. Are there any special configurations or settings I should apply or just let the Netgear Genie/Wizard do the automatic setup? Thanks for any advice.
