Sonos1 dropped connection

I tried to move my Sonos1 about 15 feet into my garage. It lost connection, became unrecognizable. 
I had to add it back as a new device. 
I finally got it connected and recognized by my WiFi, my tablets and cell phones. I then re-added my favorite music apps and got it to recognize my remote iTunes library located on my laptop
I am using the original S1 App - I have NOT upgraded to S2

Two items remain:

I rarely used it, but Radio TuneIn used to be a default part of my music options. It is no longer available. I can download the app and add it, but is there a way to add it without the App — as was the case before this afternoon’s kerfuffle?

I am fairly certain that I lost the sound enhancement—recognition of the sound quality of the room the speaker is in. How can I ‘force’ a new sound check of the room?

Thanks,

Tracy
