At our church we have Spectrum WiFi & internet. We followed the instructions to the letter on how to set up the Netgear EX2700 extenders. Everything gave a green light. When we installed them in the lower level, nothing. Nada. Zilch. Both units are almost directly below the Spectrum wireless. Our two Unifi AP AC Lite units have no problems punching through solid concrete walls, up a flight of stairs, etc. The Netgears are lucky to reach from one end of a room to another. Has anyone had this problem with using Spectrum wifi modems? Any solutions?
