ROON help needed

Not trying to be intentionally mean; apologies if I offended you. 

Jim Salk helped me set up mine with the Salk StreamPlayer III (reviewed). Though I wasn't paying super-close attention, I recall something about "pointing to", i.e. getting the ROON running on the upstairs computer to point to the StreamPlayer III. Perhaps it's that. 

You mentioned your sound room; have you gotten WiFi in there before? My sound room is so well built that I cannot get a WiFi signal to penetrate it! I had to go with a IOP (internet over power line) solution, and it works fabulously. If everything looks in pace and you haven't done WiFi in the room previously, then there is a chance that it's the WiFi not reaching/connecting and not an issue with ROON directly. Another solution which may work is a WiFi extender.  

My ROON goes from router to home computer, through IOP power lines to the room, and finishes with a hard connection. You may have to go that route. It's not a big deal; the IOP devices are relatively inexpensive and pretty easy to install. 

It sounds like setup issues; when it's set up right it's silky smooth. Call ROON support; this is what they do well. 

I have a very strong WIFI signal not only in my soundroom, but all over the house.

All of the "pointing" is there, it just won’t connect.

Do you have a phone number for Roon?  I can't find one.  Seems they only do support online and through the forums, which I had read and reread.  I did find a few people that had the same exact problem I am having and tried what they suggested, but still no go.

I’ve spent half the day on this and I’m pretty sick, (had dinner at my son’s a few nights ago and both of my Grandsons were sick, so guess what, now I have it), so maybe I missed something. I’ll try again later.

THANKS everyone for your help! I truly appreciate it.

Make sure Roon is working well from your PC, that is: as Control, Core, and Output. I am assuming this is how you have your PC set up; you mention you are using a PC (i.e. not a Mac).

Uninstall the Roon App from your iPhone. Reinstall it. If you have enabled the device (your iPhone) on the main settings page within Roon (on your PC) and the iPhone app still doesn't lock in, then contact Roon.

I don't think there should be any cross platform issues. I believe Roon Remote works fine on my wife's iPhone, while I am PC and Android based.

If you have enabled the device (your iPhone) on the main settings page within Roon (on your PC)

I don't see anywhere where I can "enable" my iPhone?  If I select the "Configure Roon OS Devices" is doesn't find anything.

On your PC:

Settings > Audio > Networked Devices

First see if your iPhone is listed there.

If it is not, hit the refresh 'Circular Arrow"

If it still does not show, Contact Roon.

If it does show, this area allows you to select it as your default Output Device. I have Not Enabled my Google Pixel XL.

 See how the remote works for you via the iPhone first (that is Do Not Enable it).

Try this approach first.
