Are these being used as the router, or as an access point? I could swear that I had set up some EERO Pro units as access points and it detected that a router was in front of it, so NAT/DHCP were changed to Bridge Mode and when I set up an EERO 6 two weeks ago, it had some problems, so I called tech support and was told to make that change. White light was on.

I have received zero trouble calls about these in 5 years. Luxul, OTOH, can KMA.
