We’re moving to bigger office next month and I need to set up a little more robust WiFi network to ensure maximum performance everywhere from the lobby to a garage on the back of the building. The new space will be about 4,000 sq. ft. and I’m comfortable tackling IT projects on my own if they aren’t too complicated and/or I can find detailed how-to instructions. Does anyone have recommendations for a fairly simple setup with multiple routers/extenders that do NOT require connecting to a separate _ext network? I currently use a Nighthawk router and love the performance, but I have a suspicion there will be too many walls and interference at the new office.
