A few things to try:-
1. What control app are you using?
I have a Denon DNP-730AE streamer (not a HEOS) and the Denon control apps are rubbish and unreliable.
I have used Mezzmo and now use BubbleUPnP control apps on an Android device (Kindle Fire 7 HDX) and these excellent apps overcame my control issues.
You can get free/trial versions to see if it works with your HEOS system.
These are not available on IPad - I have found IPad apps inferior.
2. Check the power/battery settings on your Windows 7 PC (is it a PC or a laptop?).
It maybe is sleeping to save power or battery.
Try setting it to always on.
3. I have used FIXED IP addresses for my server and streamer - as this tends to avoid confusion of changing IP addresses.
4. I also use a wired connection as this is likely to be more reliable than Wi-Fi.
5. Are you using any Internet over power adapters in your network?
My Devolo adapters, for example, have setting to sleep if they detect no traffic which I switched off.
I use Windows 10 on a dedicated slow non-powerful "netbook" and Serviio is fine (in fact it is brilliant).
I have previously used Windows 7 and 8 without issues so your Windows 7 should not be an issue - if its settings as above are OK.
Bubble UPnP allows Qobuz (which I subscribe to) and Tidal (which I have not tried) for CD quality (16 bit/44.1) streaming from the Internet - brilliant.
This overcame a Denon issue of failing to develop the products to access these high music quality Internet-based services.
This is also relevant because I have two sources Serviio and Qobuz, and when I switch Serviio is always there.
I hope these may help.
Perhaps you can explain how you are using your system and network.
