I purchased the mesh extender with the Nighthawk 6700 router. No problem with the router. The first extender I received failed to show the 2.4 and 5.0 lights. Through Chat I worked on the item for an hour. Could not get it work. NetGear finally said I should return the time to Amazon. Did so. Got a replacement. Same issue. 2.4 and 5.0 lights did not come on. Worked with support, this time by phone, for about 1.5 hours. Could not get it to work. The support person finally said she wanted to talk to a tech, who admitted that there is a bad batch of these units in the market place. So if you are going to order this unit, be forewarned. It may not work.
