Can't connect aRFR to IonXe20; works fine with Nomad; client mode PC connects

More info:  I suspected the router might be a problem, so I changed the router to access-point mode.  Now the Ion is providing DHCP and aRFR connects using the access point receiving an IP from Ion. 

When I first connected, the Ion was shown on the aRFR screen in white, NOT grayed out.  Seems like a big step forward, but when I try to connect, it grays it out and never comes back again.  I uninstalled/reinstalled aRFR and it didn't make any difference.  Everything continues to work with Nomad, including when using the access point router.

Are the Ion and aRFR in same subnet? 

Recommeded Network Address Settings: 

Ion IP Address: 10.101.100.101

Subnet Mask: 255.255.0.0

Default Gateway: 10.101.1.1

Android Device (with aRFE) Ip Address: 10.101.124.111

Subnet Mask 255.255.0.0 (or 16 instead of 24)

Default Gateway:,10.101.1.1

Provide screenshots of both setttings. 

I tried connecting Nomad client and it failed.  When I clicked troubleshoot it showed the Ion I had configured and a second Ion.  I deleted the old version and it then connected with Nomad as a client and everything worked as expected. 

In aRFR I deleted every console version except the one for the Ion.    It still would not connect.  Exit and restart did not help.  I uninstalled and reinstalled and all the old consoles returned.  I deleted everything again including the Ion console, no consoles at all.  Still could not connect.  Uninstall and reinstall and all the old consoles returned. 

This tells me some data is being retained and is likely corrupting the attempt to connect.  For some reason this problem is unique to connecting to Ion, but not Nomad.  This begs the question, How can I delete all the data stored in aRFR?  Uninstall/reinstall doesn't do it..It probably needs to retain my purchase info, but not the rest.

Why doesn't deleting a console delete the associated data?  It disappears from the list, but somewhere the data remains.  It only returns when I uninstall and reinstall, but it's there somewhere even though not on my screen.

Here are screenshots of IP stuff, but I doubt that is relevant to this problem.
