Can't login to router via Genie

From any of my devices I can connect to the router and use the internet.  However, I cannot use Genie's functionality from most of my devices.

I just purchased the R8500 and I'm having the same problem.  I can't login to the router using Genie from my iPad, iPhone6, or PC.  I tried routerlogin.net, routerlogin.com, http://192.168.0.1, http://192.168.1.1, etc.  I checked my ipconfig using the command prompt and http://192.168.0.1 was the correct ip address.  However, I still cannot use Genie from any of the 3 devices to login to the router and change settings.  I used a fourth device, Apple laptop, and it works fine with Genie.  I unplugged the cable modem and router.  This did not fix it.  I reset the router.  This did not fix it either.  The only way I can connect to this router using Genie and my PC is to use a wired connection from the PC to the router.

Also, the network map does not show many devices that are actually connected to the router and able to use the wifi internet connection.  For example, I can put my iPhone into airplane mode with wifi only and use the router's wifi connection to browse the internet.  However, the router's network map does not show the iPhone 6+ as connected.  I refreshed the map and it still does not show the iPhone 6+ as connected to the router.  The network map only shows the hardwired connections.  It's like the router doesn't know that the ipad, iphone, and PC are connected to it, although those devices are using the router's connection to reach the internet.
