inquiry for help

[prem]

Thank you David for your willing to help.

In general, it is possible to divide my music audition in two ways:

1. Network listening to music via Yamaha MusicCast devices (3 sets)
2. Headphone setup (main system) - Sonore microRendu - Luxman DA-06 - Luxman P700u.
2a. Onkyo DP-X1A ( wireless) - Luxman P700u

All Network connections are wired except the item of 2a.

3. Control points are Bubbleupnp, mconnect, Yamaha MusicCast server being controlled by Android smartphone/tablet.
4. Router Totolink A2004NS - Netgear GS 208 - headphone setup/Yamaha MusicCast devices (partially connected through Netgear - 2 pcs, partially directly from the router - 1 set).

According to my little experience from the technical point of view of the issue, there are two weak points - the router (that's why it is being substituted for another one - Ubinquiti AmpliFi HD) and the behaviour of my laptop after the resetting of Windows 10 to the intial settings. I am well-aware of the flaws of the router, but I am emphasizing once again that there were no similar problems with this very router before the resetting. The new router has come, maybe this problem will be solved...

Yes, the music files are stored on the laptop, the software is installed over there too. Frankly, at present I prefer audition of music streaming services, but nevertheless I would like to restore flawless past operation of Minimserver, since its sound and features are actually very tempted for me.

Thanks.

Sergey
