My DS with bridge (along with anything networked in my audio system) receives files (via ethernet) through and Edimax router running in WISP mode. The audio system is in the basement, and the main router is upstairs in the livingroom.
In case you’re not familiar with WISP, it stands for Wireless Internet Service Provider. Normally, it is used by certain internet providers that set up their network such that individual customers run as wifi subnetworks to a node (that’s the best way I can figure to explain it).
For home network use, and the way I use it, is the Edimax is the router for my audio system. It connects through wifi to my ACTUAL main router, and uses the main router as the WAN.
The main router ONLY sees the Edimax as a single client. This is compared to the typical “extender” that is used to extend wifi signals. In such devices, the extender will usually just do IP translation, so the main router still sees all the clients - just with different IP addresses.
In WISP mode, everything connected to the Edimax (via wifi or ethernet) cannot see anything in the main network and vice versa. It is only using the main router as WAN for internet access.
I did this so when I send files from my PC, Pi, or NAS on the Edimax to the Bridge, it doesn’t have to the Edimax, out via wifi to the main router, back to the Edimax, then to the Bridge. Note, this can also be accomplished with a managed switch.
A secondary benefit of operating as a WISP is the security of a “separated” network. The Edimax has UPnP/DLNA enabled and the main router has it disabled. There is some security risk with enabling UPnP/DLNA.
ANYWAY, I have no problem streaming Qobuz @ 24/192 via Bubble UPnP via internet through the main router/Edimax WISP to the Bridge. Bubble being on my tablet via wifi on the Edimax network.
Edit. I should note that I did look at the behavior of routers that can operate as extenders. I don’t remember all the companies I emailed, but I do remember one of them was TP-Link because I like their dedicated extenders. At the time, they all confirmed that in extender mode, there was no local routing. Everything went out to the main router for routing, then back to any local (to the extender) client.
Edit Edit. I run JRiver on both my music PC and Pi (both connected to the Edimax). The PC is (currently) connected to the DS through a Matrix SPDIF 2 (i2s), and the Pi outputs i2s directly to the DS. There is also no problem streaming Qobuz at the highest resolution through either one - either directly or as renderers via Bubble.
